Abstract 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.
