摘要
从区域角度谈江(长江)湖(洪湖)关系的演变,将其划分为江湖一体、逐步阻隔和人为调控3个阶段。详细阐述了江湖关系演变给洪湖湿地带来的不利生态影响。主要表现在:加剧围垦、改变江湖水系格局、加重自然灾害以及土壤潜育化、沼泽化,破坏了江湖复合生态系统平衡。在此基础上,探讨了重建江湖联系的必要性和对策,为长江中游江湖关系治理及生态环境建设提供借鉴与决策支持。
The evolution of relation between Yangtze River and Honghu Lake was divided into three phases:the river and the lake are integrative parts of a whole;Gradual isolation and human interference.The disadvantageous impacts on Honghu Lake wetland caused by changing river-lake relation were described in detail.These impacts are:increased cultivation,changed patterns of river-lake water systems,worsened natural disasters,soil degradation and changing to marsh land.These have destroyed the balance of river-lake ecosystem.The necessity of reconstructing the river-lake relations and countermeasures were discussed,aiming to provide an example and decision support for lake and river management and eco-environment construction in the middle reaches of Yangtze River.
