Abstract

Based on daily precipitation of Qianxi and six surrounding counties from 1984 to 2015, we estimate the risk of drought in Qianxi county during a series of return periods by probability distribution. So does the chestnut-drought risk by distribution of chestnut and relative risk grade. It is concluded that the risk of drought is higher in the southwest of Qianxi. The drought area and intensity increase with the augment of return period. Percentage of precipitation departure is -43% in Baimiaozi, Xingcheng, Xinzhuangzi and Donglianhua township when the return period is 30a. It is -52% when the return period being 100a. The distributions of chestnuts are largest in Yangjiayu and Shimenzi village, Hanerzhuang township, which are 683 and 670 ha. Influenced by hazard factor and bearing body, the risk grade is highest in most areas of Hanerzhuang, Luanyang, Shangying and Jinchangyu town.
