Multi-Hazard Meteorological Disaster Risk Assessment for Agriculture Based on Historical Disaster Data in Jilin Province, China

The impact of global climate change is gradually intensifying, and the frequent occurrence meteorological disasters poses a serious challenge to crop production. Analyzing evaluating agricultural multi-hazard disaster risks based on historical data summary occurrences development patterns are important bases for effective reduction natural regulation This paper explores technical system risk assessment establishes model at regional level from 1978–2020 in first national comprehensive census, carrying out assessments 18 major grain-producing regions Jilin province. empirical evidence shows: (1) drought flood key prevention Hotspots widely distributed study area, while hail typhoons mainly concentrated eastern region with certain regionality. (2) values four all decreased increase index. Under same index, various main areas as follows: > typhoon hail. different indices, Jiutai, Nongan, Yitong, Tongyu, other places presented high medium–high levels. (3) From spatial evolution trend, along rising hazards spatially oriented southeastern direction, central part area decreases increasing damage In addition, recommendations made three aspects: institutional construction, management model, capacity.
