以广州市为例，重点分析人类活动造成的水土流失现状与危害。广州市的水土流失类型可分为自然侵蚀和人为侵蚀，其中自然侵蚀主要有面蚀、沟蚀两种形式，在广州市范围面积分布相对较广，但侵蚀强度内并不严重；而人为侵蚀突出，侵蚀类型和强度也更为复杂多样。人为侵蚀的成因主要有：采石取土、交通道路建设、开发区建设以及坡耕地。人为侵蚀已经成为广州市水土流失灾害的主要表现形式。

With a case study in Guangzhou city, man-made soil and water loss and its hazards of Zhujiang Delta area were discussed in this paper. Types of soil and water loss were composed of physical erosions and man-made erosions. The erosion intensity of physical erosions including surface erosion and gully erosion were not serious in Guangzhou city though a relative great distribution. Contrastively, due to complicated types and high intensity, man-made erosions were main water and soil loss hazards in Guangzhou city. The main factors of man-made erosion included quarrying, traffic construction, development area building and slope tillage.
