Integrated land and water resource management of NCP with ecological services

闭湖水质恶化是世界范围内普遍存在的环境问题。白洋淀是华北平原上的一个封闭湖泊。以因板沼湖为对比研究对象，对富营养化水质项目进行了水文调查。地表水和地下水的水质分布反映了该地区水循环的实际状况。它使利用生态系统服务进行水净化的建议成为可能。在因盘沼流域，根据本研究项目的结果，开始了利用谷口湿地功能的实验。

Deterioration of water quality in closed lake is the common environmental problem in the world. Baiyangdian is such a closed lake in North China Plain. With Inbanuma lake as an object of comparative study, hydrological surveys are conducted on eutrophic water quality items. The distributions of water quality for surface and groundwater reveal actual condition of hydrologic cycle in the regions. It enables the proposal of water purification using ecosystem services. In Inbanuma watershed, an experiment using the function of wetland in valley head has started based on the outcome of this research project.
