Drought Change Trend Using MODIS TVDI and Its Relationship with Climate Factors in China from 2001 to 2010
Changes in drought trends and its relationship with climate change in China were examined in this study. The temperature vegetation drought index (TVDI) datasets recorded during 2001 to 2010 in China were constructed by using the moderate-resolution imaging spectroradiometer (MODIS) data, and the te...
