Abstract: The aim was to study the drought disaster risk distribution on winter wheat in Puyang County, Henan Province, and promote the ability of disaster prevention and mitigation. According to the surface meteorological observations of Puyang County Henan Province in 1970-2011, the number of occurrence, the area and frequency of winter white drought disaster has been compiled, and then taken as the drought disaster grades 0-1 standardized as the risk factor of drought disaster. Finally, based the Kriging spatial interpolation in ArcGIS, the figure was drawn and the meteorological disaster risk zoning map on winter wheat drought of Puyang County was established. The results showed that: Wuxing, Xinxi and Zian located in the northwest part of Puyang County which was higher winter wheat drought risk. The second was Qinghetou, Luhe, Huzhuang, and Bagongqiao. The lower risk zone was located in the southeastern part of the county, such as, Qucun, Xicheng, Liyuan, Baigang, Wangchenggu, and so on. The map on the development of the incident relief measures, improve the ability of disaster prevention and mitigation of winter wheat provides guidance of science and technology.
