摘要

Using the meteorological data of 50 stations in Jilin Province from 1961 to 2016, the demographic and economic data, and geographical information of all counties and cities aims to conduct the risk zoning of cold wave disasters in Jilin Province. The results show that, since 1961, the average number of cold wave occurrences per year in Jilin Province is 8.3 days, of which the highest number of occurrences occurred in February, followed by December and January, and the spring cold wave occurred mostly in March. From the map of cold-sea disaster risk zoning in Jilin Province, due to factors such as topography and land use distribution, the west and east of Jilin Province have a certain resilience to the disasters caused by cold waves, and the risk of disasters is low. The distribution of agricultural facilities and large areas of farmland in the central region are extremely sensitive to cold wave disasters and have a high risk of disasters. Areas with high risk of cold wave are mainly concentrated in Siping City, Changchun City, Liaoyuan City, Jilin City, northern Tonghua City and most of Baishan City. Areas with low cold wave risk are mainly concentrated in most of Baicheng City, most of Songyuan City and Yanbian Prefecture. And other places are moderately risky areas of cold waves.
