Over the past two decades (2000–2021), China has experienced a significant increase in vegetation cover. However, intricate spatial and temporal variations cover, arising from interaction of climate change human activities, remain enigmatic, particularly across diverse zones. This research endeavors to unravel dynamics cover using MOD13A1 Normalized Difference Vegetation Index (NDVI) dataset, delving into China's seven distinct zones (VZ1-VZ7). employs residual analysis, relative geo-detector techniques investigate drivers NDVI variation heterogeneity The findings reveal compelling upward trajectory NDVI, predicted during 2000–2021 period. Notably, extremely increases are discernible approximately 53.90%, 50.13%, 23.29% respectively. Among zones, VZ3 displays highest rates, yet proportion with VZ1 surpasses other analysis underscores as predominant catalyst for enhancement, although an exception is noted VZ3. Furthermore, primarily influenced by interactions between land use types humidity, sunshine duration, precipitation, especially humidity types. Significant changes can lead marked alterations structure function terrestrial ecosystems, while patterns at regional level also alter type which together exert impact on NDVI. These results accentuate importance formulating tailored ecosystem management strategies characteristics each zone ensure sustainable development ecosystems China.

Vegetation drought can reduce the net ecosystem productivity, resulting in disturbances to sustainable development of humans and nature. In this study, Health Index (VHI) was used identify vegetation drought. The spatial temporal evolution characterized using Pixel-based Trend Identification Method (PTIM) China from 1982 2020. Moreover, multiple cross-wavelet techniques were for revealing correlations between atmospheric circulation factors their combinations with results indicates that: (1) there is a decreasing trend during study period, while it will show an increasing future; (2) South prone spring summer drought, Sichuan Basin autumn winter drought; (3) spring, most obvious mitigation appears; (4) combination factors, North Pacific (NPI)-North Atlantic Oscillation (NAO)-Arctic (AO), has significant impact on across China.

Flash drought events occur frequently in Southwestern China, and a notable upward trend is predicted for the future. Attention should be given to how severity of flash droughts vegetation vulnerability hinder from recovering their original state, leading losses. Vegetation resilience was assessed dry years by adopting ‘resistance–resilience’ framework new perspective, we measured significance various characteristics affecting reduction using boosted regression tree (BRT) model. The results showed that croplands Sichuan Basin displayed low resistance droughts, whereas grasslands forests mountainous areas had high resistance. Croplands demonstrated resilience, while Guizhou province resilience. Most regions experienced especially Yunnan province. We found 2006 exhibited significant decrease LAI during events. where duration (DD) exceeded 60 days, interval (DIV) ranged 30 40 days. Forest with DD exceeding days DIV below 20 LAI. Furthermore, shrubs could recover once fell thresholds 0.34 0.30, respectively. impact species richness on can explored future research. This study reveals spatial patterns provides information preventing managing deterioration China.

With global environmental change, an in-depth understanding of the changing patterns in frequency, duration and severity drought events is great significance to regional water resources management agricultural production. The standardized precipitation index (SPI) evapotranspiration (SPEI) are two frequently used meteorological indices characterizing characteristics. elucidation differences between important work reduce uncertainty hazard analysis give suggestions appropriate for detection. Shandong Province considered be one major production bases northern China. However, comparative suitability SPI SPEI this area spatial variability have not been systematically studied, which forms basis research. In study, we identified according run theory with consideration merging neighboring medium-term events. results showed that both can efficiently describe study by these were quite similar. most severe event 11 months 12.8, respectively, a joint return period 90 years, 12 12.98, 65 years. given SPEI, however, generally longer larger than those at same station. A comparison using bivariate copula function indicated minor existed station SPEI. distributions mean as well periods suggested northwest part Weifang city more likely experience events, also relatively higher potential areas.

ABSTRACT Specific leaf area (SLA, per unit dry mass) occupies a central position in both community assembly and ecosystem functioning. Although SLA has significant phylogenetic signals, how to what extent the evolutionary history influences variation remain poorly understood. In this study, based on dataset containing 1264 plant species belonging 549 genera 141 families gymnosperms, monocots, eudicots across China, we analyzed of climatic conditions soil properties SLA, calculated signals quantified relative contributions (represented by interspecific relatedness intraspecific variation) SLA. The results showed that accounts for 50.46% total variance followed (36.12%), (30.68%), (24.74%). Along tree, split between angiosperms gymnosperms had largest contribution Other detailed splits (e.g., monocots eudicots, within Rosidae, etc.) but much smaller contributions. relationship environmental variables (climatic properties) was different with having larger than properties, implying interactive effects environment Within woody angiosperms, deciduous evergreen exhibited differential responses factors, suggesting non‐negligible role longevity explaining Our highlighted more important previous studies. Neglecting such great could lead biased conclusions if rate does not keep pace rapidly changing environments future.
