水土流失是黄土高原农业生产的主要灾害,是黄河下游河患的根源。制止水土流失是治黄的核心,是发展当地农、林、牧生产的根本施措。本文拟通过对黄土高原水土流失的现状及其原因分析,探讨治理水土流失的途径。一、水土流失的现状黄土高原的水土流失由来已久,早在更新世黄土堆积过程中就有侵蚀发生,当时速度较慢,参与人类活动影响以后侵蚀加快。尤其是秦汉以来日益加剧,越到近期越严 Soil and water loss is the main disaster of agricultural production in the Loess Plateau and the root cause of rivers in the lower Yellow River. Suppression of soil and water loss is the core of governance of the Yellow Sea and a fundamental measure for the development of the local production of agriculture, forestry and animal husbandry. This paper intends to analyze the status quo of soil and water loss in the Loess Plateau and its causes, to explore ways to control soil and water loss. I. Status of Soil and Water Loss The soil and water loss in the Loess Plateau has existed for a long time. Erosion occurred as early as the Pleistocene loess deposits. At that time, the erosion was slow and the erosion accelerated after being involved in human activities. Especially since the Qin and Han dynasties have been aggravating day by day, the more recent the more strict
