【摘要】：农村水环境承载力的定量估算及其动态变化特征研究有助于了解农村地区水资源供需平衡和水环境质量状况,为新农村建设规划和水环境可持续发展提供科学依据。本文以太湖流域镇江区域为研究对象,结合云模型改进模糊综合评价法,构建农村水环境承载力的PSR分析框架和评估指标体系,并结合雷达图、云模型发生器分析其动态变化特征及影响因素。结果表明:云模型能够较好地表征农村水环境承载力的变化特征;农村水环境承载力对太湖流域镇江区域的工农业废水排放、供水总量和治水投入的要求更高;2010~2014年太湖流域镇江区域农村水环境承载力基本保持稳中上升的趋势,但总体处于弱承载状态,且丹阳丹徒润州京口。
[Abstract]:The quantitative estimation of rural water environmental carrying capacity and its dynamic change characteristics are helpful to understand the balance of water resources supply and demand and the quality of water environment in rural areas, and provide scientific basis for the planning of new rural construction and sustainable development of water environment. Taking Zhenjiang region of Taihu Lake basin as the research object, combining with cloud model to improve fuzzy comprehensive evaluation method, this paper constructs the PSR analysis framework and evaluation index system of rural water environmental carrying capacity, and combines with radar map. Cloud model generator is used to analyze the dynamic characteristics and influencing factors of cloud model generator. The results show that the cloud model can better represent the change characteristics of the rural water environmental carrying capacity, and the rural water environmental carrying capacity has higher requirements for the discharge of industrial and agricultural wastewater, the total amount of water supply and the input of water control in the Zhenjiang region of the Taihu Lake Basin. From 2010 to 2014, the carrying capacity of rural water environment in Zhenjiang region of Taihu Lake Basin remained a steady and rising trend, but generally in a weak load state, and in Danyang Dantu Runzhou Jingkou.
