Development and Application of Comprehensive Drought Evaluation Model for Irrigation District in North China
Preview AbstractDroughts are severe meteorological disasters in China, and more comprehensive evaluation methods for droughts can provide a reliable reference for policy-making in reducing the impact of droughts. The existing methods of drought evaluation are lacking universally, and cannot be used generally. Based on the theory of Variable Fuzzy Sets, a comprehensive drought evaluation model is proposed to solve the problem. The methodology for the proposed solution is written in this paper and is applied in the Qucun Yellow River Irrigation Region. The results have shown that the model is not only reasonable and feasible, but also simple and practical. The model and its methods can provide academic support and serve as reference for policy-making for the comprehensive evaluation of droughts in the North Region of China.
