Abstract: To study the drought risk zoning of the Haiyuan County in Ningxia, the authors first used meteorological observation data from 12 regional stations and one large monitoring station, and took into consideration of the disaster inducing environment, hazard factor, bearing body and anti-disaster ability, and then adopted AHP analysis method to assign weight, and ArcGIS to resample, interpolate and grid compute the data after they were rasterized. Finally, the Haiyuan County drought disaster risk zoning based on the 250 m grid resolution was obtained. The results showed that three towns, including Haicheng, Guanqiao and Gancheng, were the highest incidence areas of drought disaster risk, while Qiying, Zhengqi and Liwang which had higher probability of irrigation and Guanzhuang which had more annual rainfall were the lowest incidence areas of the drought disaster. This study provided more evidence for the migration of Haiyuan County, and also provided the technical support for the future agricultural structure adjustment and long-term planning.
