Reviewer 2 Report (New Reviewer)
Comments and Suggestions for AuthorsReview report
The article does a fantastic job of presenting the use of statistical tools to analyze some satellite data. Still, the way it is given and the overall background of the work should be improved. I present some of my reflections and suggestions below. Introduction The general background of the studies undertaken is made briefly and the main disadvantage is lack of the international linking to the topic presented and methods used in the research. The literature review covers the rich achievements of China scientists in the discussed research area. Although this is an accurate and very objective selection of literature, it should also include the experiences of a broader, international scientific community.
Materials and methods
The Study area (subchapter 2.1) is described too synthetically. The authors put great effort into scientific analyses; however, the background for all these efforts is given in very general terms.
As it is mentioned in the title, the study area is a “typical tourist region”, and vegetation is analysed from the perspective of human activity; therefore, the population structure, spatial characteristics of the population within the island, human occupation, inhabitants/tourists ratio, details on tourists and touristic development: figures, types of touristic activity, etc. should be detailed, as these are factors assumed as influenced vegetation. All of this is partially related to the factors driving FVC presented in Table 1: these factors were accurately pointed, but the article needed to provide their characteristics for the study area - we only learned about precipitation and elevation in Hainan island. The other factors were not detailed.
The factor “land use type” is mentioned many times in the text, as one of the most important, for example 311-312, but we cannot find out what is the specifics of land use in the study area; OK, there is some tourist activity and forested land (any management in a forest or only conservation?).
The other question is about vegetation characteristics. The reader does not learn much about the vegetation on the study area, how it is spatially differentiated, what vegetation habitat types can be distinguished? Perhaps the vegetation spatial differentiation is another factor influencing FVC?
In the section 2.2. (Data sources) the Landsat data are mentioned in one sentence only, and yet these data are the basis for all further analysis. Were all Landsat 5 and 8 data collected every 16 days over the entire analyzed period of twenty years used in the research? Were data from specific dates used? Were the data analyzed within scenes or in a different way?
The statistical methods used in the studies (subchapter 2.3.) were indicated sequentially, but described in a variety of ways: some of them are presented in detail, others are not; some symbols are explained, others are not. It would be better to standardize the presentation of the individual methods.
Figure 1 - Legend: the height unit is missing; Hainan is mentioned as “city” – so it is not clear for the reader out of China: is it island, city or country?
Figures 8 and 9 – the green, red solid and dashed lines should be explained in a legend,
About some other measurement units:
75 – “reforestation projects with a total area of 504700 hm²” does it mean “hectometres” ? Can it be shown in square kilometres? By the way, there is no figure how big in fact is the island.
102 – does 16d mean days?
286-288: „In addition, trend analysis showed that the changes of FVC on Hainan Island over the past 21 years were mainly characterized by not-significant improvement and extremely significant improvement” – I don’t feel it sounds logical. The comment of the results should be clarified.
314 – “vegetation construction” can you explain the phrase?,
328-330 – the sentence is not clear,
343-344 - referring to a global ecology is a good opportunity to point some evidence in the literature; in the Discussion chapter, there are still few references to international studies, as in the Introduction; the authors’ family names in the reference [43] are incorrect,
375-376 - in the final remarks/Conclusions it would be good to develop the last sentence “Our findings help to provide a reference basis for vegetation protection policies in Hainan Island”; how practically the results can help in the island management, and who can use the results?

Materials and methods
The Study area (subchapter 2.1) is described too synthetically. The authors put great effort into scientific analyses; however, the background for all these efforts is given in very general terms.

The other factors were not detailed.
Response: Thank you, as your kindly suggestions, we have revised it. We have added some touristic details in Materials and methods
The factor “land use type” is mentioned many times in the text, as one of the most important, for example 311-312, but we cannot find out what is the specifics of land use in the study area; OK, there is some tourist activity and forested land (any management in a forest or only conservation?).
Response: Thank you, as your kindly suggestions, we have added a land-use map for the study area.
The other question is about vegetation characteristics. The reader does not learn much about the vegetation on the study area, how it is spatially differentiated, what vegetation habitat types can be distinguished? Perhaps the vegetation spatial differentiation is another factor influencing FVC?
Response: This research mainly explores the response mechanisms of vegetation greenness to the geographical environment, socioeconomic development and tourism development in Haikou and Sanya.
In the section 2.2. (Data sources) the Landsat data are mentioned in one sentence only, and yet these data are the basis for all further analysis. Were all Landsat 5 and 8 data collected every 16 days over the entire analyzed period of twenty years used in the research? Were data from specific dates used?

Figure 1 - Legend: the height unit is missing; Hainan is mentioned as “city” – so it is not clear for the reader out of China: is it island, city or country?
Response: Thank you, as your kindly suggestions, we have revised it.
Figures 8 and 9 – the green, red solid and dashed lines should be explained in a legend,
Red represents a significant negative impact, green represents a significant positive impact, and the dashed line represents a non-significant impact
About some other measurement units:

314 – “vegetation construction” can you explain the phrase?,
vegetation restoration
328-330 – the sentence is not clear,
Response: Thank you, as your kindly suggestions, we have revised it. Researcher has shown that FVC fluctuated in mountainous areas due to the heterogeneity of topography conditions such as elevation, aspect, and slope
343-344 - referring to a global ecology is a good opportunity to point some evidence in the literature; in the Discussion chapter, there are still few references to international studies, as in the Introduction; the authors’ family names in the reference [43] are incorrect,

Response: Thank you, as your kindly suggestions, we have revised it.
Our findings can help the government of Hainan to make an effective reference basis for vegetation restoration management.

Reviewer 2 Report (New Reviewer)
Comments and Suggestions for AuthorsThe authors have made several corrections to the text, slightly improving its quality. However, these changes are insufficient. The elements and two literature items added to the Introduction have not sufficiently internationalized the subject matter, and international experience in the subject matter and methodology have not been presented enough clearly. In the methodology, the use of Google Earth Engine is not sufficiently explained and justified; one can at least point to the experience of using this tool presented in the literature. The input data and methodology are the essential elements by which one can judge the reliability of the results. In the statistical methods, only some abbreviations have been explained; others have been left unexplained.
Similarly, the natural characteristics of the study area have not been presented sufficiently, and the detailed characteristics of the natural parameters (the factor driving FVC, vegetation itself) that I requested have not been presented. The topography figure, which characterizes this important geographical element, has been removed, and a map of land use and administrative division (a very good figure) has been added, which is also very important, so both should be included in the text. By the way, the caption under the figure should be more adequate. The conclusions haven't been developed.
There are probable errors in citations, e.g.:
line 79 – citation 25 inadequate to the content,
line 104 – citation 25 is in the wrong place, inadequate to the content; in the previous version, some other article was cited here,
line 126 – citation in the form of a name and year instead of a number;
so, the order of other citations may need to be clarified.
In my opinion, the Authors should still work on the text.

Response: Thank you, as your kindly suggestions, we have revised it. We have added some details about the Google Earth Engine in Introduction.
However, the large-scale and long-term FVC research is often required to deal with the massive image data, leading to the significant challenges on research advancement. With the development of remote sensing cloud computing platforms such as Google Earth Engine (GEE), researchers can quickly obtain medium to high-resolution remote sensing datasets for large or small-scale areas, such as the Landsat dataset, thereby breaking through the barrier of local computing capabilities [28]. Compared with traditional remote sensing analysis methods, GEE platform can ensure the quality of image processing and greatly reduce image processing time, especially in research on vegetation index analysis [29]. Currently, this platform has been widely used in studies on extracting crop area, water body extraction methods, and remote sensing monitoring of land cover [30,31].
Similarly, the natural characteristics of the study area have not been presented sufficiently, and the detailed characteristics of the natural parameters (the factor driving FVC, vegetation itself) that I requested have not been presented.

Round 3
Reviewer 2 Report (New Reviewer)
Comments and Suggestions for Authors
The text in its current form is better than the first version. Unfortunately, not all of the suggestions I included, especially in my first assessment, have been taken into account. There is a lack of internationalization of the research background, a lack of detailed geographical characteristics of the research area, and a lack of proper characterization of the FVC driving factors i.e. the details typical to Hainan island have not been specified, their diversity within the research area has not been indicated; the conclusions have not been expanded with any specifics. Even though the article concerns vegetation, the name of even a single species that grows on the island has not been included. However, information on the methodology has been supplemented, a better figure with maps has been included, and several items of literature have been added. The corrections have improved the whole to some extent, so the text is acceptable.
Final observations:
Line 117: Capital letter at the beginning of a sentence: "We...".
Figure 1: The elevation model shows that there are depressions within the island (land below sea level), down to -66 m. I suspect that this is not true.

Reviewer 3 Report
Comments and Suggestions for AuthorsOverall and Major Comments
This paper aims to explore the spatial and temporal evolution characteristics and driving factors of vegetation greenness in tourism areas, and predict the future development trend of vegetation greenness. With Hainan Island as the research area, the use of the methods was also relatively targeted. In the selection of influencing factors, the geographical environment, social development and tourism development are included in the comprehensive consideration, and the previous research has been supplemented.
Generally speaking, I think this is a job with a workload, but not an innovative paper. There are already too many similar articles.

⑵Page 4, lines 122-124:σ, CV, etc are the letters in the formula (7). In 2.3.3, there is no correspondence between the formula description and the chapter.
⑶Page 7, line 188:the writing format of 0.005 and 4.58 should be consistent.
⑷Page 7, line 195:0.98 is inconsistent with the value in Figure 5b.
⑸Page 9, lines 213-215:the uppercase and lowercase letters should be consistent.
⑹Page 11, lines 265-268: The expression should be the conclusion of the author's previous empirical analysis, and why do you quote the conclusions of others?

Reviewer 1 Report
Comments and Suggestions for AuthorsI would like to thank the authors for their improvement.
The manuscript was almost done for publication.
One correction is needed for wrong citation below.
L65: La Plata Basin [25] -> La Plata Basin [5]
[5] is the correct reference.
Also, supplementary materials should be posted on the journal web site for reader's abundant understanding on what is going on the research area.
Reviewer 2 Report
Comments and Suggestions for AuthorsThe objective of this manuscript, entitled “Spatiotemporal dynamics and driving factors of vegetation greenness in typical tourist region: A case study of Hainan Island, China” is to determine the spatial and temporal variations characteristics of vegetation greenness and driving factors in Hainan Island. The topic falls within the scope of the Journal.
Although the manuscript had been revised according to the reviewer’s comments, there were more problems and it is recommended that the manuscript be reconsidered after a major revision.
1, In Section Introduction, although the literature review on the progress of research related to vegetation greenness on Hainan Island had been added, simple citations were done only, with no relevant research findings presented.
2, In Section 2.2 Data sources, Lack of ways to harmonize data from different sources to a uniform spatial scale (kilometers or what kind of scale needs to be explained).
3, In Section 2.2 Data sources, what are the definitions of tourism economy and tourism services, and what kind of spatial scale data are they? Can they represent tourism development? How do they act spatially on vegetation greenness? Is there any intersection with socio-economic development such as land use types, GDP, etc.? Please add relevant material.
4, It is suggested that the city and county names should be overlapped on Figure 1b, Figure 3, Figure 4, and Figure 5.
5, In Line 221 to 223, please briefly explain how the respective impacts were calculated.
Reviewer 3 Report
Comments and Suggestions for AuthorsThe author has made many revisions to the article, but in terms of scientific research, it can be called a work rather than a study, and I still haven't seen any improvement in innovative points.
