崇明农村河道生态治理试点工程——以万平河为例

Chongming River Ecosystem Management Projects in Rural Areas:Taking Wanping River for Example

针对崇明农村河道水质较好但水体浑浊的特点,提出采取生态护坡建设、水生态净化系统构建、岸坡生态绿化等工程措施重点改善河道生境,使之成为生物生长繁殖适宜的环境。其中,水生态净化系统构建工程中为去除水中携带的悬浮物,并逐步净化水质达到生态及景观功能要求,设置了强化预处理区、滨岸带水生植物种植区、沉水植物悬床种植区及沉水植物种植区等处理环节。在满足河道岸坡安全性、耐久性的前提下,达到农村河道"自然、生态"的治理目标。

The water quality of rural rivers in Chongming is good, but with the characteristics of turbid water. For this feature, ecological protection slope, ecological purification system building, eco-green slope and other engineering measures are proposed. The purpose is to improve the river habitat, making it to be suitable for biological growth and reproduction. In order to remove suspended solids carried in water, and gradually achieve the ecological and landscape functional requirements, the ecological purification system building project comprise several processing sectors, such as the strengthen pre-processing area, riparian zone for hydrophyte planting, submerged plants hanging bed planting area and submerged plants planting areas. With the premise of satifying the river bank slope safety and durability, it can reach the governance objectives natural, ecological for rural rivers.
