【摘要】：维系健康的河流水环境是我国流域管理的迫切需求,然而中国河流水环境治理仍然面临污染控制难、水资源供需矛盾突出和人类活动影响剧烈等方面的挑战,如何恢复和维系健康的河流水环境,充分发挥河流的服务功能成为河流水环境管理研究的热点.本文讨论了水环境可恢复性的概念,从水资源及开发利用程度、环境容量及纳污水平、河流生态、社会经济、环境治理与管理水平等5个方面探讨河流水环境可恢复性的影响驱动因子;将可变模糊识别模型与改进的AHP相结合,提出了一个可以量化水环境可恢复性的评价模型.论文以汉江中下游襄阳段和仙桃段为代表段,评价了汉江中下游流域水环境系统可恢复性的年际变化以及空间变化,并深入分析了水环境可恢复性时空变化的原因,研究结果可为汉江流域水环境保护和管理提供科学依据.
[Abstract]:Maintaining a healthy river water environment is an urgent need for watershed management in China. However, river water environment management in China is still faced with the challenges of pollution control, outstanding contradiction between water supply and demand, and severe impact of human activities. How to restore and maintain a healthy river water environment and give full play to its service function has become a hot topic in river water environment management. This paper discusses the concept of recoverability of water environment, including water resources and the degree of exploitation and utilization, environmental capacity and pollution absorption level, river ecology, social economy, etc. This paper discusses the influence driving factors of river water environment recoverability from five aspects, such as environmental control and management level, and puts forward an evaluation model that can quantify the recoverability of water environment by combining the variable fuzzy recognition model with the improved AHP. Taking Xiangyang and Xiantao sections in the middle and lower reaches of the Hanjiang River as the representative sections, the paper evaluates the interannual and spatial changes of the recoverable water environment system in the middle and lower reaches of the Han River, and analyzes the causes of the spatial and temporal changes of the recoverable water environment. The results can provide scientific basis for water environment protection and management in Hanjiang River Basin.
