Study of optimal allocation of water resource in Minqin County of Shiyang River Basin
摘要
Abstract
There are four sectors in Minqin County that respectively control and manage the use and allocation of water resources in agriculture,industry,urban and rural resident's daily life,and ecology.Using Defei Er combined with variation coefficient to calculate comprehensive benefit coefficient of these four sectors.The calculated values for these four sectors were 0.238,0.280,0.209,and 0.280,respectively.Applied them into linear programming equations for optimal allocation scheme,the results showed that optimal allocation scheme for different departments at three typical levels were (108 m3):dry year:agriculture:2.222,industry:0.1616,residents daily life:0.082,ecology:1.5677 ; average year:agriculture:2.223,industry:0.1616,residents daily life:0.082,ecology:1.8390; wet year:agriculture:2.223,industry:0.1616,residents daily life:0.082,ecology:1.8394.The Entropy Change Principle was utilized to evaluate the feasibility of these allocation schemes.The results showed that ecological water accounted for 38.87％ ～42.72％ of total water,far more than 18.92％ of current allocation scheme.The calculated entropy values of 2010 and 2020 years were 3.62 and 3.49,showing a decrease trend,which indicated the scheme was proved feasible.关键词
