Abstract:Vegetation on slopes not only serves as landscape function but also aids erosion control and slope stability. Vegetation should be considered as the primary protection method for all man-made slopes of soil and weathered rock. The basic principles and composite effects of vegetation slope are summarized in this paper. All aspects of the slope vegetation technology in Hong Kong,including the principles,design,opportunities,implementation and maintenance of planting,are introduced in detail. According to the experiences in Hong Kong and the situations of the mainland of China,some opinions and suggestions on slope vegetation are proposed.
