Entropy Weight Method, Vulnerability to Drought in Agriculture, Fuzzy Comprehensive Evaluation ModelAbstract
In order to systematically evaluate the vulnerability of agricultural drought in Henan Province, based on the meteorological, agricultural, water resources and socio-economic data of Henan Province from 2007 to 2023, 15 indicators were selected from the two dimensions of sensitivity and recovery, through quantitative qualitative indicators and entropy weight method Determine the weight, build weighted comprehensive evaluation models and fuzzy comprehensive evaluation models respectively, and conduct comparative analysis on the vulnerability of agricultural drought in 18 cities in the province. The result shows that the evaluation result of fuzzy comprehensive evaluation model is more reasonable. During the study period, the overall agricultural drought vulnerability of the province showed a downward trend, but the regional differences were significant, especially in southern and eastern Henan, the regional vulnerability continued to be high. Finally, rationalization suggestions and countermeasures are put forward according to the evaluation results, in order to improve the regional agricultural drought resistance capacity.
