Abstract: The evaluation model on drought disasters for middle and later rice in Hunan province was established by using the human survival environmental risk assessment method, based on the factors, such as the frequency of disasters, the area and the intensity of disasters and rice production. Furthermore, risk division on drought disasters for rice production in Hunan province was conducted by using GIS technology. The results showed that the high risk region was south Hunan and Huaihua region, and others were low or slight risk region.
