Regional Patterns of Vegetation Dynamics and Their Sensitivity to Climate Variability in the Yangtze River Basin

To better understand the mechanisms of hydro-ecological cycle in changing environments Yangtze River Basin (YZRB), it is valuable to investigate vegetation dynamics and their response climate change. This study explored spatial patterns essential triggers regional differences by analyzing variations 1982–2015 period at different time scales interannual variability sensitivity variability. The results showed that normalized difference index (NDVI) increased significantly last three decades, but displayed great spatiotemporal scales. central part YZRB dominated forests shrublands was more sensitive than source region YZRB, which alpine meadows tundra (AMT). contribution variables (VSI) had large differences, solar radiation temperature were dominant factors. Furthermore, 57.9% increasing VSIs, especially south-central part. Consistent with distributions elevation types, divided into five patterns, largest NDVI trend Region III VSI IV. Moreover, exhibited fairly consistent all subregions, contributions varied greatly among regions.
