摘 要:东江是香港特别行政区主要的饮用水水源,源区水环境直接关系到珠江三角洲和香港的饮用水安全;但近年来由于果业开发导致东江源区水土流失现象严重,水质呈恶化趋势。为防治东江源区坡地果园水土流失,应根据区域水土流失现状,结合地形、地质、土壤条件,通过设置山边沟、草沟等工程措施,同时配合采用梯壁植草、节水覆盖等植物措施进行综合防治,达到改善东江源区水质的目标。Dongjiang River is the main drinking water source of the Hong Kong Special Administrative Region.Water environment in source area is directly related to drinking water security in Pearl River Delta and Hong Kong.In recent years,soil erosion and water loss has been serious and water quality has been deteriorated due to the development of fruit industry in the source region of Dongjiang River.In order to control soil erosion and water loss in slope orchard in this region,based on present regional situation of soil erosion and water loss as well as geographical,geological and soil conditions,some control measures should be conducted,such as designing "hillside ditches" and "grass channels",planting grass on terrace ridge and water saving coverage,so as to improve the water quality in Dongjiang River.
