摘要:
水资源可持续利用是经济和社会可持续发展的重要条件。本文以洞庭湖流域水资源系统为例，采用模糊识别模型，充分考虑洞庭湖流域水资源分布及其利用特点，选取评价指标并建立模型，得到流域内各水系近几年水资源可持续利用程度评价值。研究表明，洞庭湖流域各水系中沅江水资源的可持续利用程度最高，而洞庭湖区最低。2011年洞庭湖流域的可持续利用程度较往年有所下降，整个洞庭湖流域的水资源可持续利用程度还有较大的上升空间。研究结果对于促进流域水资源安全有效利用，经济、人口与生态环境的协调发展有重要意义。
The sustainable use of water resources is a very important condition of economic and social sustainable development. The fuzzy recognition model is used to assess the water resources sustainable using of Dongting Lake basin in this paper. The utilized characteristics and water resources distribution of Dongting Lake basin are considered plenty. Select evaluation index and model is established, and the evaluation value of the water resources sustainable utilization is get within the river basin in recent years. The research result shows that the degree of water resources sustainable use of Yuanjiang River is the highest, while the lake area is the lowest. At the same time, the degree of sustainable use of Dongting Lake basin has declined in 2011 than in previous years. The sustainable utilization level of water resources has still a large increase space in entire lake basin. The study has significance to promote the safety and effective use of water resources, the coordinated development of economic, demographic and ecological environment.
