水土流失是历史产物,是由各方面的因素造成的。决定土石山地水土流失发展发生的自然因素,主要包括地形、气候、土壤、地质及植被等各种条件,这些因子之间在水土流失发展过程中,相互制约、相互促进、相辅相成的进行着。因此,在综合治理过程中,分析水土流失的形式及其发生发展的基础上,进而研究影响水土流失发生发展因素,是防治水土流失,提出有效措施的前提与依据。
Soil and water loss is a historical product that is caused by various factors. Natural factors that determine the occurrence of soil and water loss in mountainous areas include the topography, climate, soil, geology and vegetation. These factors are mutually restricted, mutually reinforcing and complement each other in the process of soil and water loss development. Therefore, on the basis of analyzing the form of soil and water loss and its occurrence and development during the process of comprehensive management, and then studying the factors that affect the occurrence and development of soil and water loss, it is the prerequisite and basis for preventing and controlling soil and water loss and putting forward effective measures.
