Research on Establishing Eco-clean Small Watershed in the Source of Dongjiang River

寻乌县地处东江源头区,属于东江上中游国家级水土流失重点预防区,其流域水质与生态环境关系到香港及粤东城市的饮用水问题,在寻乌县东江源头区建设生态清洁小流域保护水源具有十分重大的意义。以东江源小流域为例,阐述了寻乌县东江源头区水土流失及人居环境现状,提出了建设生态清洁小流域关键技术,并依据本工程的实施情况给出了建设生态清洁小流域的几点建议。

The source of the Dongjiang River is in Xunwu County which is national key prevention area of soil and water loss in middle and upper stream of Dongjiang River. It is greatly significant to establish eco-clean small watershed to protect water source in the source of the Dongjiang River of Xunwu, because the water quality and ecological environment of this area are related to drinking water problem of Hong Kong and the east of Guangdong province. This paper describes the present situation of soil and water loss and human settlements in the headwater of Dongjiang River, puts forward the key technologies of establishing eco-clean small watershed and gives some suggestions based on the actual circumstances.
