基于云模型的安康市水资源保护效果评价

Evaluation of Water Resources Protection Effect of Ankang City Based on Cloud Model

从水资源系统、水生态环境系统、社会经济系统3个方面出发,构建出基于水量、水质、水生态、水资源经济四维并重的水资源保护效果评价体系;参考水利现代指标体系等级和标准,选用3个准则层,共筛选出16个评价指标因素并按照合理的数值区间划分成4个等级Ⅰ、Ⅱ、Ⅲ、Ⅳ,采用熵权法和基于X条件云发生器算法的正态云模型来建立水资源保护效果评价模型,对安康市2013~2017年水资源保护效果进行综合评价。结论为:安康市水资源保护效果连续5年逐年改善。通过查阅市水利局和环保局公告资料,结论与安康市实际情况相符,说明模型具有可行性与合理性。

From the three levels of water resources system,water ecological environment system and social economic system,a system of water resources protection evaluation is constructed based on water quantity,water quality,water ecology and water resources economy.With reference to the standard of the water conservancy modern indicator system,16 index factors are divided into four grades:Ⅰ,Ⅱ,ⅢandⅣaccording to reasonable numerical intervals.The entropy weight method and the normality cloud model based on the algorithmic called X conditional cloud generator are used to establish an evaluation model for water resources protection evaluation.The data of five years from 2013 to 2017 are selected to comprehensively evaluate the water resources protection effect of Ankang City.The effect of water resources protection in Ankang as been improved for five consecutive years.The conclusion is consistent with actual situation in Ankang,which shows that the model is feasible and reasonable.
