湖南省洞庭湖区北部地区水资源保障策略研究

Study on Water Resources Allocation Scheme of North Dongting Lake Area in Hunan Province

本文主要针对三峡水库运行后,清水下泄,江湖关系发生严重调整,长江通过荆南三口进入洞庭湖水量减少、断流时间延长,由此带来了湖区缺水严重、水质恶化、生态功能退化等问题,开展了洞庭湖北部地区水资源配置方案研究,在立足本省水资源实际情况及需求基础上,提出了通过河湖水网大连通建设,建成拥有"四线"、"两厢"、"多点"的点线面相结合的生态水网体系,构建五个水资源分区及24个水资源配置单元,为洞庭湖水资源配置规划、供需水预测、水资源合理配置研究提供参考依据,且作为今后一定时期内水资源开发利用的重要依据,为实现区域水资源可持续利用、治理保护盒支撑经济社会可持续发展提供科学依据。

This paper focused on the situation that after the operation of the ter discharged, the relationship between river and lake were seriously adjusted, through three outlets of the Jingjiang flowed into Dongting Lake, the drying time Three Gorges reservoir and the wa- less water from the Yangtze River prolonged, which brought the prob- lems of serious water shortage, water quality deterioration, ecological function degrada search of water resources allocation strategy in Hubei area of Dongting Lake, in based tion in the lake, carried out re- on the actual situation and the needs of water resources in our province, it was proposed to construct an ecological water system with ＂four lines＂, ＂two sides＂, ＂multiple points＂, combing points, lines and faces through the construction of river lake water system connection, build five water resources divisions and 24 water resources allocation units, providing referential basis for the study of water resources allocation plan, water supply and demand forecasting, and rational allocation of water resources of Dongting Lake, and becoming an important basis for the development and utilization of water resources in a certain period of future, in order to provide scientific basis for realizing sustainable utilization, control and pro- tection of regional water resources, and supporting the sustainable development of the economy and society.
