Abstract: To analyze the risk loss of agricultural crops caused by drought, agricultural drought risk in Anhui Province was assessed and regionalized based on data of agricultural disaster and crop sowing area from 1991 to 2012. The results showed that drought was the main agricultural natural disaster in Anhui Province. In the 22 years, drought accounted for 42.1% and 40.1% of agricultural natural disaster affected area and disaster area, respectively. In the cities of Anhui Province, the changes of affected area and disaster area had strong synchronization. Agricultural drought in Anhui Province had short period and high frequency. The drought affected area was generally not more than 60%, and the risk probability was once in 357.1 years. According to the spatial and temporal distribution of the drought risk, Huaibei area and Jianghuai area had higher drought risk than other areas.
