洞庭湖湿地景观结构与生态工程模式研究

Preliminary Study on Wetland Landscape and Ecological Engineering Models in Dongting Lake

在碟形盆地圈带状景观结构控制下，洞庭湖区形成了以浅水湿地、过水湿地和渍水湿地为主的我国最大的湖泊地区湿地景观。由于不合理的开发活动，近年来出现了湿地面积减少、生态功能衰退、资源过度利用与闲置并存等问题。为了合理开发湿地资源，必须强化湿地综合管理，稳定湿地面积，建设复合高效湿地生态系统。

The wetland in Dongting Lake, the largest lacustrine region in China, can be divided into three classes: the shallow waters, lake and river shore, paddy fields The large scale reclaimation has made some harmful influence on the ecological environment, i e comprehensive utilization being low, flood regulation function weakening and ecological function degrading In order to utilize and protect wetland rationally, the following measures must be taken: 1) controlling the scale of wetlands reclamation and making great efforts to construct high-efficiency multi-ecosystem; 2) stabilizing the area of wetland; strengthening wetland comprehensive management
