基于集对指数势的流域水资源系统脆弱性影响因子分析

Driving Factors Analysis of Basin Water Resources System Vulnerability Based on Set Pair Exponential Potential

针对传统集对势定义的必要条件为对立度不等于零(不具有一般性)的问题,利用指数函数改进传统集对势,提出集对指数势的定义,建立基于集对指数势的流域水资源系统脆弱性影响因子分析方法,并对巢湖流域水资源系统脆弱性影响因子进行分析。结果表明,巢湖流域水资源系统脆弱性的影响因子主要包括水资源模数、水资源利用率、人均水资源量、工业废水处理率、人口密度、干旱受灾率、水利工程投资占GDP比例,可见利用集对指数势进行流域水资源系统脆弱性影响因子分析具有可行性。

The necessary condition of traditional set pair potential is alternative degree not equal to zero, that does not have a generalization. Therefore, exponential function is used to improve the traditional set pair potential, and the defini tion of set pair exponential potential is proposed. And then, driving factors analysis of basin water resources system vul- nerability method is established based on set pair exponential potential. Finally, this analysis method is applied to Chaohu basin. The results show that the driving factors of Chaohu basin water resources system vulnerability are water resources modulus, water utilization rate, per capita water resources, treatment rate of industrial wastewater, population density, damage area of drought disaster, and GDP rate of hydraulic engineering investment. So, it is feasible to use the proposed method to analyze driving factor of basin water resources system vulnerability.
