ABSTRACT: 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.
