摘要
我国传统的修堤建闸、抵御洪水的治河理念,阻断了江湖联系,造成湿地的生态萎缩。为改善湿地的生态环境,保护湿地的生物多样性,提出了新的多目标闸口调度机制,替代传统的、以防洪抗旱为目的的调度机制,力求促进江湖联系,增加湿地活力;为保障该机制的运行和实施,提出了闸口调度影响区的管理办法;并以涨渡湖为例进行了讨论。
Traditional ideology for river regulation is to build the dyke and lake gates along rivers for flood defence. Such modes have obstructed the connexity between rivers and the round lakes, and caused the shrinking of wetland. To improve and protect the wetland＇s bio-environment and biodiversity, the new multi-purpose mechanism of gate management is proposed for the recovery of the connexity. Also management measures for impact zones are suggested to make the new mechanism into effect, and the management of Zhangduhu Lake is discussed as an example.
