1. Introduction
As a unique ecosystem on earth, wetlands not only have rich biodiversity, but also undertake important ecological service functions such as climate regulation, water storage and flood control, and water quality purification. However, with the continuous expansion of human activities, such as reclamation, pollution, over-exploitation, etc., the wetland ecosystem is facing unprecedented challenges, which has brought about a profound impact on the natural environment and social economy [
1,
2,
3]. Faced with the severe situation of the increasing degradation and destruction of wetland resources, countries all over the world have taken effective measures for ecological management [
4]. On the one hand, governments are strengthening the construction of laws and regulations on wetland protection, clarifying the social responsibility of wetland protection through legislation, and standardizing wetland utilization behavior to ensure the effective protection of wetland resources. On the other hand, research institutions are promoting scientific research and monitoring and a timely grasp of the changes in wetland resources [
5,
6], and providing a scientific basis for governments to formulate scientific and reasonable protection strategies.
In addition, countries are also strengthening ecological restoration and sustainable utilization and protecting the healthy environment of wetland ecosystems by restoring degraded wetlands and establishing nature reserves. At the same time, they are adhering to the principle of sustainable utilization and rationally developing wetland resources to achieve the unity of economic benefits and ecological benefits [
7]. However, how to effectively evaluate the effects of wetland ecological management has gradually become the focus of national governments and scientific research institutions [
8,
9,
10]. For discussing the comprehensive effect of wetland ecological management, scholars focus on in-depth research from the perspective of the economic effects, ecological effects, and social effects of wetlands, to provide a scientific basis for wetland protection and sustainable development.
Research on the economic effects of wetland ecological restoration has made remarkable progress around the world. This field is not only related to the protection and restoration of the natural environment, but also has a profound impact on the social and economic development of regions and even countries [
11]. Through multi-angle and multi-level research, scholars continuously reveal the internal connection between wetland ecological restoration and economic benefits, which is providing strong support for policy formulation and scientific management [
12]. Around the world, research on the economic effects of wetland ecological management has been highly valued. Since the signing of the Wetland Convention in 1971, the global importance of wetland protection has been increasing continuously, and research on the economic effects of wetland ecological restoration has also achieved fruitful results.
Costanza et al. (1997) [
13] published the article “The value of the world’s ecosystem services and natural capital” in the international journal
Nature, the first systematic evaluation of global ecosystem services, in which the value of wetland ecosystem services plays an important role. This study provides an important reference framework for assessing the economic effects of wetland ecological restoration worldwide [
14,
15,
16,
17]. In China, the study of the economic effects of wetland ecological management started at the end of the last century, and gradually became an important branch of ecological economics. Cui et al. (2012) [
18] and other scholars carried out an in-depth analysis of the demand, supply, benefits, and costs brought by the protection from the perspective of economics, and emphasized the status of lakes and wetlands as important ecological capital for regional sustainable development. Fang et al. (2024) [
19] found that although ecological service functions such as carbon fixation, oxygen release, and the water purification of lake-type wetlands have non-exclusive and non-competitive characteristics, their economic value in promoting regional ecological balance, improving the living quality of residents, and attracting ecological tourism cannot be ignored. Through scientific wetland management and protection, the utilization efficiency of wetland resources can be effectively improved, and the win–win situation between economy, society, and environment can be realized [
20].
In addition, scholars are also concerned with the positive role of wetland ecological management in promoting the development of the agriculture, fishery, and tourism industries. For example, Hagger et al. (2022) [
21] found that the protection and restoration of coastal wetlands and mangrove wetlands can not only help to resist marine disasters and protect biodiversity, but also provide rich natural bait resources for local fisheries and promote the transformation of the economic value of fishery resources. At the same time, through the development of wetland ecotourism, wetland resources have been transformed into economic advantages, which has become an important way to achieve green development in many regions [
22]. In recent years, with the wide application of modern technologies such as remote sensing technology, geographic information systems (GISs), and big data analysis, research on the economic effects of wetland ecological restoration has become more accurate and efficient [
23]. By constructing the value evaluation model of wetlands’ ecological service value, scholars carried out a quantitative analysis on the economic contributions of wetland resources [
24], which provided a scientific basis for policy makers. For example, by evaluating the contribution of wetlands to water purification, flood control and disaster reduction, climate regulation and other aspects, the economic value of wetland ecological restoration can be more intuitively displayed, so as to enhance the attention paid and support from all sectors of society for wetland protection.
The ecological benefit assessment of wetland ecosystems, as the core index to measure their health status and sustainability, is not only related to the balance of natural ecology, but also has a profound impact on the well-being and development of human society. In this field, Goorani et al. (2021) [
25] revealed that wetlands provide irreplaceable support for the earth’s ecosystem through their unique ecological service functions, such as the precise regulation of water resource allocation, effective mitigation of flood disasters, natural water purification, and maintenance of biodiversity as a habitat for many species. These functions not only guarantee the stability and harmony of the natural environment, but also bring significant positive effects to the economic development of human society, the improvement of life quality, and disaster prevention [
26,
27]. With the deepening of the understanding of the importance of wetlands, the research on wetland ecological benefit assessment has made remarkable progress since 2000, and a relatively perfect theoretical system and method system has been gradually constructed. For example, through remote sensing technology, geographic information systems (GISs), ecological models, and other modern scientific and technological means, scientists can more accurately monitor the ecological indicators of wetland ecosystems, such as the vegetation coverage, water quality parameters, species diversity, etc., and then scientifically evaluate the comprehensive contributions of wetlands to the ecological environment and human society [
28,
29,
30]. These research results not only enrich the connotations of wetland science, but also provide a solid scientific basis for the formulation of scientific and reasonable wetland protection and management policies. Research on wetlands’ ecological benefits in Chinese academic circles started late, but significant progress has been made in recent years. Through field monitoring and data analysis, scholars have studied the ecological benefits of the wetland ecosystem in depth [
31,
32]. For example, the ecological benefits of different types of wetlands, such as mangrove wetlands, swamp wetlands, and lake wetlands, were evaluated to clarify the specific contributions of wetlands to the ecological environment. These studies provide an important reference for wetland ecological management and ecological environment protection in China.
The effect assessment of wetland ecological management involves many aspects, including economic benefits, ecological benefits, social effects, and so on. Among them, economic benefits and ecological benefits are important aspects for evaluating the effect of wetland ecological restoration, while the social effects reflect the impact of wetland ecological restoration on human society [
33]. At present, theoretical and method research on social effect assessment is becoming a hot topic of academic research. Research on the theoretical framework, evaluation object, and index system of social effect evaluation is constantly being deepened [
34,
35], which provides a scientific basis for the social effect evaluation of wetland ecological restoration. At the same time, with the continuous development of artificial intelligence and big data technology, social effect assessment has also begun to apply these advanced technologies to improve the accuracy and scientificity of the assessment [
36]. The methods of social effect assessment mainly include qualitative assessment and quantitative assessment. Through in-depth analysis of the collected data, the qualitative evaluation of the significance and relevance is used to obtain a comprehensive and descriptive evaluation of social effects [
37]; relatively speaking, the quantitative evaluation depends on the accuracy of data statistics, the rigor of the analysis methods, and the social effects as quantitative indicators, to provide intuitive and specific evaluation results [
38]. The two are comprehensively applied to constitute a comprehensive and profound evaluation system of social effects. In practical applications, it is necessary to choose appropriate evaluation methods according to different purposes and scenarios. Therefore, the social effect evaluation of wetland ecological restoration is an important basis for evaluating the effectiveness of governance and guiding follow-up work [
39]. Through a comprehensive and scientific evaluation of the social effects of wetland ecological restoration, the actual effect of governance measures can be clarified [
40], the impact of ecological governance on the regional ecological environment, social economy, residents’ lives, and other aspects can be understood, and it can provide strong support for the further optimization of governance strategies and improving governance efficiency.
At present, although some progress has been made in the study of the economic and ecological effects of wetland ecological restoration, there are still some deficiencies in the study of social effects, which are mainly reflected in the lack of social perception and feedback mechanisms of specific regional governance results, and the lack of in-depth analysis of local residents as a key interest group. This study aims to supplement the existing research by extensively collecting social perception dimension data, refining various indicators, and conducting an in-depth analysis of the impact of social perception on overall satisfaction. China’s important wetland ecosystems are research subjects, as a typical case study area, and we aim to comprehensively and deeply evaluate the actual social effects of wetland ecological restoration from the perspective of surrounding residents’ satisfaction and the perception of ecological governance projects. The study of this paper has two important objectives, which are as follows:
On the one hand, this study not only focuses on the effectiveness of ecological governance measures in the improvement of the physical environment, but also focuses on how these measures affect and are integrated into local communities, including residents’ quality of life, livelihood style, and improvements in the awareness of environmental protection. Through questionnaire surveys, in-depth interviews, and participatory observation, residents’ perceptions of and satisfaction with changes before and after the implementation of wetland protection policies and governance projects are assessed, so as to build a comprehensive evaluation system for the social effects of wetland ecological restoration.
On the other hand, this study hopes to provide a vivid and community-based Chinese wetland ecological restoration case study for the international community through the case analysis of Poyang Lake. It not only reveals the multi-dimensional social impact of ecological governance, but also provides useful reference and inspiration for the sustainable management and protection of wetland resources worldwide.
5. Discussion
This paper deeply analyzes the satisfaction of the surrounding residents of Poyang Lake in China with the effect of wetland ecological restoration, as well as their profound perceptions of wetland protection. By constructing a multi-dimensional research framework, it tries to reveal the real attitude and depth of understanding of the residents of wetland protection in an all-round and multi-level way.
Multi-dimensional perspective of satisfaction evaluation: This study found that the overall satisfaction of residents with wetland ecological restoration is a complex and multi-dimensional construct, which is closely related to the restoration of wetland ecological functions, the perfection of leisure and entertainment functions, the completeness of infrastructure construction, and the positive impact of wetlands on local reputation.
This conclusion not only confirms the importance of wetland protection for improving the quality of life of residents, but also highlights the role of wetlands as a bridge between the harmonious coexistence of the natural ecosystem and human society [
46]. It is worth noting that, compared with previous studies [
47], this paper discusses the influencing factors on satisfaction, although this influence was not directly found for families’ distance to the nearest wetland and its significant relationship with satisfaction, but this does not rule out influence in specific situations (such as Poyang Lake’s surrounding drainage or wetland accessibility with high special geographical environment) where factors may produce subtle influence. This discovery tells us that regional characteristics and individual differences should be fully considered when evaluating the effectiveness of wetland construction.
In-depth analysis of wetland function perception: In terms of wetland function perception, this paper reveals that residents attach great importance to wetland ecological function, such as regulating and storing water sources, purifying water quality, and regulating climate, etc. This finding coincides with many research conclusions at home and abroad [
48], which further emphasizes the irreplaceable nature of wetlands as the “kidney of the earth”. However, the unique feature of this paper is that it is not only limited to a discussion of ecological functions, but also provides a thorough analysis of the positive economic, social, and cultural impacts brought about by wetland ecological restoration. Through rich research data, this paper shows how wetlands become an important carrier for promoting local economic development, improve living quality of life, and inheriting regional culture. Different from other studies [
49], the residents in this study generally believe that the tourism benefits brought by wetlands far exceed the agricultural and fishery benefits. This discovery provides a new perspective and way of thinking for wetland conservation and sustainable utilization.
Subtle effects of geographical and gender differences: This paper also touches on the impact of regional heterogeneity and gender differences on wetland perception. Residents in different areas have significant differences in their perception of wetlands due to different geographical environments and socioeconomic conditions [
16,
50]. For example, the residents near the swamp and mangrove coexist with the wetland, having a more profound and comprehensive understanding of the wetland. At the same time, gender differences also affect residents’ perception of wetland functions to some extent. Although this difference may not be significant in the same region, it reminds us that the gender perspective should be considered when formulating wetland protection policies to ensure the fairness and inclusiveness of the policies. However, when exploring these differences, this paper mainly focuses on the analysis at the overall level, and fails to deeply analyze the specific differences in different groups and regions, which leaves a broad space for future research.
Reflection on research methods and prospects for future research: While affirming the research value of this paper, we should also face up to its shortcomings. Although the collection method of electronic questionnaires is convenient and efficient, it may limit the age range of the respondents to some extent and underrepresent the views of older age groups. In addition, although taking satisfaction as the main index to evaluate the social effects of wetland construction reflects the subjective feelings of residents, it lacks certain objectivity. In order to make up for this deficiency, future research could use the method of multi-index construction and comprehensively consider the actual results of wetland construction in ecological, economic, social, and other aspects, so as to build a more stable and comprehensive evaluation system.
6. Conclusions and Policy Implications
Based on the perspective of the satisfaction and perception of residents around Poyang Lake in Jiangxi Province, this study deeply explores the social effects of wetland ecological governance. The main conclusions are as follows: First, they are highly recognized and widely supported. The vast majority (87.5%) of the surveyed residents are satisfied or very satisfied with the ecological restoration of Poyang Lake wetland, indicating that the project has achieved remarkable results in protecting and restoring the natural environment, and has won high recognition and active participation from local residents. This result not only reflects the ecological benefits of wetland governance, but also highlights its positive role in promoting community harmony and improving the quality of life of residents. Second, a comprehensive understanding of complex mechanisms: Through the model regression analysis, we found that age, education, quality of life (such as increases in recreational space and regional sense of belonging), and improvements in environmental quality (such as the diversity of bird species, water and air quality) are the main factors affecting residents’ satisfaction. These findings reveal the complex mechanisms of the formation of residents’ satisfaction, involving multiple social, economic, ecological, and cultural levels. Finally, the multi-dimensional nature of residents’ perceptions: Residents’ perceptions of the wetland ecosystem cover service functions, economic benefits, ecological benefits, and cultural inheritance. Farmers have a high perception of wetland ecological protection; especially in the aspects of wetland water source regulation and climate and water purification, more than 60% of farmers agree. However, the perceptions of ecological functions, such as protecting species and providing wildlife habitats, is relatively low, indicating that residents’ understanding of these deep-seated functions needs to be strengthened. In terms of economic income, residents generally recognize that wetlands can increase tourism and fishery incomes, but their perception of the increase in agricultural income and the promotion of industrial and commercial development is relatively limited. In terms of social benefits, residents relatively recognize the value of wetlands as tourism resources and scientific research and education bases, but their perception of improving employment opportunities, service levels, and infrastructure construction is still insufficient.
Based on the above research conclusions, the following three policy implications are proposed:
First, we will strengthen ecological education and raise public awareness of environmental protection. In view of the significant positive impact of education levels on residents’ satisfaction, it is suggested to strengthen ecological education and environmental protection publicity and improve public awareness of environmental protection, especially for teenagers, so that they can better understand and support the wetland protection work. Through school education, community activities, media publicity, and other channels, the value and functions of the wetland ecosystem should be popularized, and the consensus on and sense of responsibility for wetland protection of the whole society should be enhanced.
Second, we will pay attention to the win–win situation of ecology and people’s livelihoods. In the process of wetland management, the living needs and interests of residents should be fully considered to ensure the coordination between ecological protection and community development. For example, by increasing the amount of recreational space and enhancing the sense of regional belonging, we can improve residents’ quality of life and enhance their support for and satisfaction with wetland governance. At the same time, new models of wetland protection and economic development should be explored, such as the development of ecological tourism and green agriculture, so as to achieve a win–win situation between ecology and residents’ livelihood.
Third, infrastructure construction is required to be improved to ensure the sustainable development of wetlands. Infrastructure construction is an important support for wetland protection. We should increase investment in the infrastructure around the wetland, improve environmental protection facilities such as sewage treatment, garbage collection, and transportation, and prevent wetland pollution. At the same time, we should strengthen wetland monitoring and scientific research capacity construction and have a timely grasp of the wetland’s ecological conditions to provide a basis for scientific decision-making. In addition, we should establish and improve the wetland protection laws and regulations system, strengthen law enforcement, and ensure the sustainable and healthy development of the wetland ecosystem.
