摘要
受围湖造地、污水直排、无序养殖等人为活动的影响,湖北地区的湖泊数量及面积急剧下降,江(河)湖阻隔日趋严重,水系日益破碎,湖泊生态功能日渐萎缩,生物多样性逆向演替。从分析湖北地区湖泊生态水环境的问题入手,讨论了水系网络修复的必要性,提出重建江(河)湖动态联系、修复水网生态环境的理念和方法,同时介绍了武汉市汉阳地区四湖连通水力调度工程和新洲县涨渡湖引水工程两个实例以及所取得的成效。
Influenced by human activities, such as lake reclamation, direct sewage discharge, uncontrolled aquatic cultivation etc., the lakes and lake area in Hubei province decrease sharply, the river and lake separation becomes more and more serious, the water system becomes more and more broken, the ecological function of lake dies out gradually and antitromic succession of biological variety becomes more and more serious. From the analysis of ecological water environment of lakes in Hubei province, this paper discusses the necessity of hydrographic net restoration and puts forward the concept and method of hydrographic net ecological environment restoration, and at the same time, introduces hydraulic regulation works for the connection of the lakes and the Yangtze river in Hanyang administrative area of Wuhan city and the water-diverting project for Zhangdu lake in Xinzhou county of Wuhan city as well as the achievements.
