在总结围湖造田带来的生态环境影响的基础上 ,就退田还湖工程对洞庭湖生态环境的影响进行了分析 ,获得了退田还湖能扩大洞庭湖的蓄洪能力、改善湖泊局地气候和水质、有利于生物多样性保护和水资源的可持续利用 ,同时指出了移民集中建镇安置可能带来的水质污染风险 。
This paper analyssed the effects of re submerging particular polders on the ecological environment of Dongting Lake based on summarizing the ecological environment effects of land reclamation.The favorable conclusions of the project such as expending the ability of passing and storing floodwater,improving the local climate and water quality,favoring the biodiversity protection and the sustainable utilization of water resource were obtained.It is indicated that the migratory towns construction will bring risks of water pollution.Proposals and countermeasures of Dongting Lake ecological environment protection were put forward.
