重庆市水资源可持续利用能力的模糊评价
发布时间:2018-10-19 18:19
【摘要】:针对重庆市水资源时空分布不均、水资源利用率低以及水环境恶化等现状,利用重庆市政府公开资料及统计资料,采用熵权和模糊综合评判相结合的方法,对重庆市2005年-2014年水资源可持续利用能力进行评判.根据最大隶属度的原则将水资源可持续利用能力划分为5个等级,并采用等级赋值法对评价结果进行量化,计算出水资源可持续利用指数.评价结果表明:重庆市水资源可持续利用能力整体上呈上升趋势,2005年-2009年略有波动,降水量的多少对水资源可持续利用能力影响较大,2010年-2014年,水资源可持续利用能力指数从2.88持续上升到4.04,其中水资源开发利用程度贡献最大.水资源与环境矛盾突出,成为制约水资源可持续利用的主要因素.
[Abstract]:In view of the present situation of the uneven distribution of water resources in time and space, the low utilization rate of water resources and the deterioration of water environment in Chongqing, the method of entropy weight combined with fuzzy comprehensive evaluation is adopted by using the public and statistical data of Chongqing municipal government. The ability of sustainable utilization of water resources in Chongqing from 2005 to 2014 was evaluated. According to the principle of maximum degree of membership, the ability of sustainable utilization of water resources is divided into five grades, and the evaluation results are quantified by the method of grade assignment, and the index of sustainable utilization of water resources is calculated. The evaluation results show that the capacity of sustainable utilization of water resources in Chongqing is on the rise as a whole, and fluctuates slightly from 2005 to 2009, and the amount of precipitation has a great impact on the capacity of sustainable utilization of water resources. The capacity index of sustainable utilization of water resources increased from 2.88 to 4.04, in which the degree of water resources development and utilization contributed the most. The contradiction between water resources and environment is prominent and becomes the main factor that restricts the sustainable utilization of water resources.
