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。 Taking Guangzhou as an example, this paper focuses on analyzing the status quo and harm of soil and water loss caused by human activities. The types of soil erosion in Guangzhou can be divided into natural erosion and artificial erosion. Among them, there are mainly two types of natural erosion, such as surface erosion and gully erosion. The distribution in Guangzhou is relatively broad, but the erosion intensity is not serious. However, man-made erosion Prominent, erosion type and intensity are more complex and diverse. The main causes of human erosion are: quarrying and borrowing, construction of traffic roads, construction of development zones, and sloping farmland. Human erosion has become the main manifestation of the soil erosion in Guangzhou.
