Based on the precipitation data of Hunan in 1960-2002, the evaluation model on hazard of drought was constructed. And the spatial patterns of drought hazard were analyzed with GIS techniques. And then the pattern of drought risk was analyzed according to the basic principles of risk analysis of natural disaster. The results showed that the hazard of agricultural drought showed decreasing trend from west to east in the space in Hunan Province. The risk distribution of agricultural drought also showed obvious east-west differentiation. The west, southwest and south was high-risk area, middle and east parts were low-risk area and mountain area was high-risk area generally.
