Social and Economic Value Evaluation of Water Resource Based on Fuzzy Mathematics and Emergy Theory

Abstract

Water resources is one of the important drivers of socio-economic development, but the value of water resources in society is not clear. In order to accurately describe the impact of water resources on socio-economic value, a socio-economic value evaluation index system for water resources is established. This paper is based on the theory of utility value of water resources. Discussed how to use fuzzy mathematics and benefit sharing coefficient method to calculate the socio-economic value of water resources in different industries. Take the Golog Zang A.P in the source region of the Yellow River as an example. Calculated the socio-economic value of water resources for residential life, irrigation planting, industry, construction and tertiary industry. Finally, analysis results show that the value of comprehensive water resources in the study area is between 9.4-40CNY, tertiary industry highest, lowest value for domestic water. The calculation results provide a reference for the rational and efficient use of regional water resources and the scientific formulation of water resources policies.
