Special Issue Information

Dear Colleagues,

This Special Issue is a follow-up of the first Special Issue, entitled “Response of Vegetation to Climatic and Anthropogenic Drivers in the Plateau” (https://www.mdpi.com/journal/atmosphere/special_issues/BJNR1SIJR4) published in Atmosphere.

Vegetation is a natural link connecting various spheres and the main body of the terrestrial ecosystem; moreover, it is an indicator of regional climate change and human activities, and plays an important role in regulating carbon, water, and energy cycles. With diverse vegetation types and a complex geographical environment, vegetation growth in the plateau region is more sensitive to climate change and human activities, and is a sensitive and vulnerable zone for global climate change and ecological environment changes. Since the beginning of the Anthropocene, the vegetation ecosystem has been significantly changed by both climate warming and human activities, mainly in the form of glacial retreat, land desertification, and grassland degradation. If humans continue to develop and use the earth's resources unreasonably in the future, it will lead to the gradual depletion of natural resources and further degradation of the ecosystem, which will threaten the ecosystem and ecological security of the plateau region. Therefore, it is of great scientific and practical significance to investigate dynamic changes in plateau vegetation and the interrelationship between vegetation, climate change, and human activities, in order to understand the current state of the global plateau ecosystem, restore ecosystem balance, and promote the sustainable development of the ecosystem.

This Special Issue will focus on papers that contribute to a better understanding of the characteristics of synergistic vegetation–water–soil changes in plateau regions in the context of climate change and increased human activities. Examples topics of interest include (but are not limited to) the following:

  • Response of vegetation (growth, health, phenology, etc.) to climate change and human activities in plateau regions;
  • Relationship between extreme weather changes such as droughts and floods and vegetation biomass;
  • Effects of land use/cover change or ecological engineering on regional vegetation (cover, leaf area index, etc.);
  • Differences in vegetation response to climate change and human activities for different substrate conditions (elevation, slope, etc.);
  • Relationship between environmental factors, such as glacier, snow, permafrost, etc., and vegetation changes in the context of climate warming;
  • Impacts of excessive logging and grazing activities on vegetation;
  • Characteristics of vegetation response to urbanization process;
  • Response of vegetation ecosystem quality to coupled atmosphere–water changes;
  • Climate–vegetation–soil–water–ecosystem feedback mechanisms.

This call solicits process-level studies based on both observations and model simulations. This includes intensive observational field campaign studies, long-term in situ observatories, satellite observations, and simulations from plot-scale process-oriented models or regional/global Earth system models.

Gross primary productivity (GPP) is a key carbon flux in the global carbon cycle, and understanding the inhibitory effects of drought on GPP and its underlying mechanisms is crucial for understanding carbon–climate feedback. However, current research has not sufficiently addressed the threshold dynamics and regional differentiation of GPP responses to the synergistic effects of meteorological drought (MD) and soil moisture drought (SD), particularly in the drought-sensitive Mongolian Plateau. This study focuses on the Mongolian Plateau from 1982 to 2021, using the standardized precipitation index (SPI) and standardized soil moisture index (SSI) to characterize MD and SD, respectively. The study combines the three-threshold run theory, cross-wavelet analysis, Spearman correlation analysis, and copula models to systematically investigate the variation characteristics, propagation patterns, and the probability and thresholds for triggering GPP loss under different time scales (monthly, seasonal, semi-annual, and annual). The results show that (1) both types of droughts exhibited significant intensification trends, with SD intensifying at a faster rate (annual scale SSI12 trend: −0.34/10a). The intensification trend strengthened with increasing time scales. MD exhibited high frequency, short duration, and low intensity, while SD showed the opposite characteristics. The most significant aridification occurred in the central region. (2) The average propagation time from MD to SD was 11.22 months. The average response time of GPP to MD was 10.46 months, while the response time to SD was significantly shorter (approximately 2 months on average); the correlation between SSI and GPP was significantly higher than that between SPI and GPP. (3) The conditional probability of triggering mild GPP loss (e.g., <40th percentile) was relatively high for both drought types, and the probability of loss increased as the time scales extended. Compared to MD, SD was more likely to induce severe GPP loss. Additionally, the drought intensity threshold for triggering mild loss was lower (i.e., mild drought could trigger it), while higher drought intensity was required to trigger severe and extreme losses. Therefore, this study provides practical guidance for regional drought early-warning systems and ecosystem adaptive management, while laying an important theoretical foundation for a deeper understanding of drought response mechanisms.
