海河流域地下水生态水位研究

Research on Groundwater Ecology Water Level of Haihe River Basin

海河流域是我国水资源严重短缺的地区之一,由于长期不合理地开采地下水,引发了一系列生态环境问题,如地面沉降、地下水漏斗扩大、水质恶化、海水入侵等。恢复海河流域的生态环境对于区域的可持续发展意义重大,文章根据海河流域地貌单元将海河流域划分为3种类型:山前倾斜平原、中部平原和滨海平原,并确定了不同类型区地下水的生态水位。最后提出了恢复海河流域地下水生态水位的措施。

The river basin in Haihe river is one of the area lacking of water resources in our country , since irreasonably extracing groundwater over a long period of time, a series of ecology environment problems are initiated,for instance: surface subsidence,groundwater hopper enlarges, water quality deteriorates , the sea water intrudes and so on. It is important for area sustaining development that resumes ecology environment of river basin in Haihe river. The paper divides river basin in Haihe river into three kinds of types on the basis of the physiognomy cell of river basin: the slopes plain before mountain, middle plain and seaside plain and assures groundwater ecology water levels of different type area. Finally, proposes the step of recovering groundwater ecology water level of river basin in Haihe river.
