摘要
在水资源配置方案评价研究的基础上,建立了新的水资源配置方案优选方法。从资源效益、社会效益、生态效益和经济效益4个方面考虑,分别选取人均用水量、渠系水利用系数、水资源开发利用率等15个比较典型的指标进行研究。通过改进熵值法确定权重,并对TOPSIS方法和灰色关联方法分别进行改进,然后将改进的算法结合起来,共同用于求解不同方案的相对贴近度。通过改进TOPSIS-灰色关联方法计算的结果和实际情况相符,进而验证了方法的有效性和可行性。
On the basis of summarizing the previous studies on the evaluation of water resources allocation schemes, a new method for optimizing the allocation of water resources was established. From the perspectives of resource efficiency, social benefit, ecological benefit and economic benefit, 15 typical indicators such as per capita water consumption, canal water utilization coefficient and water resources development and utilization rate were selected for research. The weights are determined by the improved entropy method, and the TOPSIS method and the gray correlation method are improved respectively, and then the improved algorithms are combined to solve the relative progress of different schemes. The results of the improved TOPSIS-grey correlation method are consistent with the actual situation, and the validity and feasibility of the method are verified.
