| 中文摘要: |
| 将民勤县的用水部门分为农业、工业、生活、生态四个方面。运用德菲尔结合变异系数法分别得出各部门的综合效益系数为:0.238、0.280、0.209、0.272；代入线性规划目标方程得到三个典型年的不同部门的最优配置方案为(亿m3):枯水年:农业2.222、工业0.1616、生活0.082、生态1.5677;平水年:农业2.223、工业0.1616、生活0.082、生态1.8390；丰水年:农业2.223、工业0.1616、生活0.082、生态1.8394。采用熵变原理验证该方案的可行性。结果表明:生态水量占总水量的38.87％～ 42.72％,远高于现行配置方案的18.92％.将2010与2020年的数据代入计算得熵值分别为3.62、3.49,呈减小趋势,说明方案可行。 |

| 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 eeology. 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(108m3):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 alloeation seheme. The ealeulated entropy values of 2010
and 2020 years were 3.62 and 3.49, showing a deerease trend, which indicated the seheme was proved feasible. |
