Concurrent Climate Extremes and Impacts on Ecosystems in Southwest China

Global warming and its associated changes in temperature precipitation have significantly affected the ecosystem Southwest China, yet studies that integrate are inadequate for quantitatively assessing impacts of extreme events on ecosystems. In this study, return period concurrent climate extremes characterized by deficit spatial temporal dynamic patterns their ecosystems were assessed using high-precision data, as well NDVI NPP data collected 1985–2015 period. The results show 2009 event had a about 200 years. periods individual factors overestimated or underestimated. Concurrent reduced spring annual Normalized Difference Vegetation Index (NDVI) net primary productivity (NPP) China. magnitude reduction vegetation greenness increased with intensity events. beginning autumn 8.8% 23%, 2.23% 7.22%, respectively. Under future scenarios, could be shortened, which would more severe impact regional
