水土流失是黄土高原普遍存在的严重问题。富县位于陕北黄土高原沟壑区向黄土丘陵沟壑区的过渡带,塬面、丘陵、山地、河谷阶地等黄土高原区的主要地貌类型均有,是这类地区水土保持重点县之一。摸清该县水土流失状况,不仅为搞好全县农业区划、防治水土流失提供依据,而且对了解整个黄土高原水土流失的类型、分布规律、危害程度、发展趋势、防治途径也是有益的。为此,我们结合土壤普查,对富县水土流失状况作了全面调查,绘制了1/50,000的土壤侵蚀图。
Soil and water loss is a serious problem on the Loess Plateau. Fuxian County is located in the transitional zone between the gully region of loess plateau and gully region of the Loess Plateau in northern Shaanxi Province. The main landform types are in the Loess Plateau, such as the plateau, hills, mountains and valley terraces, and is one of the key counties in soil and water conservation in this area. Finding out the status of soil and water loss in this county not only provides the basis for improving the zoning and prevention and control of soil and water loss in the county, but also helps understand the types, distribution, hazard, development trend and prevention and cure of soil and water loss in the whole Loess Plateau. To this end, we combined with the soil census, a comprehensive survey of the status of soil and water loss in Fu County, the plot of 1 / 50,000 of soil erosion.
