Snow disaster effect and risk assessment of overwintering crops and facility agriculture in Jiangsu
摘要
Abstract
In order to explore the damage degree and distribution law of snow disaster on overwintering crop and facility agriculture in Jiangsu Province,the daily meteorological data,such as the minimum temperature and snow depth of 71 national meteorological stations in Jiangsu Province from 1978 to 2020,the DEM elevation data,the socioeconomic data related to wheat,rape and facility agriculture were used.A risk assessment model for overwintering crops and facility agriculture by AHP-CRITIC and other methods was constructed and the snow disaster risk level was classified.Results show that the lowest temperature in snow days decreases from northwest to southeast.The number of snow cover days decreases from west to east.The maximum snow depth was positively correlated with the distance from the ocean.The snow disaster highest risk areas are concentrated in west part of the northern Huaihe River while the high risk areas are in the western region between Yangtze River and Huaihe River.Central part of the northern Yangtze River and west of southern Jiangsu are medium risk areas.Low-risk areas are distributed in coastal area and east of southern Jiangsu.关键词
