物质的侵蚀- 搬运- 堆积是地貌发育的主要过程。水土流失目前主要是指第一阶段即地貌发育的侵蚀过程。地貌的侵蚀一般被分为两类:自然侵蚀和人为侵蚀,而人为侵蚀被认为是水土流失的主要原因。笔者认为,人类活动固然加剧了侵蚀过程的发生,但它是在自然侵蚀的基础上进行的,它是符合自然侵蚀规律的。在目前的社会条件下,水土流失的治理不仅仅是减少人类活动的影响,而应该是使人类活动在地貌演化过程中扮演因势利导的角色,使其向着人类有利的方向发展。
Material erosion - handling - accumulation is the main process of landscape development. At present, soil erosion mainly refers to the erosion process of the first phase of landform development. Erosion of landforms is generally divided into two types: natural erosion and artificial erosion, and artificial erosion is considered as the main reason for soil and water loss. The author believes that although human activities aggravate the erosion process, it is based on natural erosion, which is consistent with the law of natural erosion. Under the current social conditions, the governance of soil and water loss is not only to reduce the impact of human activities, but to make human activities play a role of guide in the evolution of landscape so that it can be favored toward mankind.
