River channel ecological restoration method based on demand of aquatic organisms for hydrological conditions
The invention discloses a river channel ecological restoration method based on a demand of aquatic organisms for hydrological conditions. The river channel ecological restoration method includes the steps that firstly, a river channel is investigated and surveyed, then the location of an ecological restoration area is determined, spur dikes are arranged, a deep pool is formed by dredging, flood plain is constructed, and a planting area of ecological restoration plants is determined. According to the demand of the aquatic organisms for hydrological and habitat conditions, river channel configuration is appropriately transformed, meanwhile suitable aquatic organisms are arranged in different habitat areas, so that a river channel ecosystem is effectively restored, the self purification capacity of the river channel is improved, the biodiversity is restored, and the function of the ecosystem is enhanced. Meanwhile, the river channel ecological restoration method can increase the stabilityof the river embankment without affecting the flood discharge capacity of the river channel, and has excellent effects in improving an ecological function, a landscape function and a social functionof a river.
本发明公开了一种基于水生生物对水文条件需求的河道生态修复方法，首先对河道进行调查和勘测，再进行生态修复区位置确定、布置丁坝、清淤形成深潭、河漫滩构建、确定生态恢复植物的种植区域等操作；本发明依据水生生物对水文及生境条件的需求，对河道形态进行适当的改造，同时在不同的生境区域配置适宜的水生生物种类，有效修复河道生态系统，提高河道的自净能力、恢复生物多样性并提升生态系统的功能；同时，该修复方法在不影响河道行洪能力的情况下，增加河流堤岸的稳定性，在提升河流的生态功能、景观功能和社会功能方面均有优异效果。
