摘要：黄土高原地区由于其特殊的地质、地形地貌以及气候条件、人类活动，使之成为土壤侵蚀强烈、类型复杂、时空分布集中的严重水土流失区，面积达64万km2，其范围覆盖了几乎整个黄河中游地区和上游地区的大部，占黄河流域面积的80.5%，是黄河泥沙的来源区。要治理和开发黄河，必须加强黄土高原地区的水土流失防治。本文介绍了黄土高原水土流失的基本情况、目前的治理情况，最后提出了治理措施。

Approach of Preventing Soil and Water Loss in the Loess Plateau

Abstract: The Loess Plateau,due to special natural condition and long-term human activities,becomes severe soil and water loss area with intense soil erosion,complicated category,concentrated spatial and temporal distribution,and the  main source of sediment yield.To harness and develop the Yellow River,prevention and control of soil and water loss on the Loess Plateau should be strengthened.The paper puts forward the concept of harmony of nature and people，it also normalizes human being''''s construction activities and prevention behaviors in the light of law;a large area of vegetation can be restored by natural regeneration capability;by the comprehensive rehabilitation to improve ecological environment，relying on scientific and technological management to increase soil conservation and ecological consruction benefit.The basic approach of harnessing soil and water loss is three strategies with ten measures as following“taking prevention control as main task, taking protection as the top priority”,“strengthening rehabilitation and emphasizing the focus”,“creating new mechanism,normalizing management”to identify ten-year target of prevention and control.
