Abstract由于引起土壤侵蚀的自然和社会经济条件有明显的地域差异特征,所以土壤侵蚀过程各地区不一样。土壤侵蚀的评价目的是查明土壤侵蚀过程及其特征的区域分异规律,阐明侵蚀产生的原因及其发生、发展的演变趋势,为水土流失的预防和治理及资源的合 理开发利用提供科学依据。本文在土壤侵蚀评价的内容和方法上着重对土壤表面水力侵蚀类型作了讨论。
Other Abstract Soil erosion is a process that the soil materials in soil layers are displaced and transported by external agents. According to the characteristics of erosion processes and materials of soil erosion can be divided into five types. The main properties of each of them are introduced.In this paper, contents for an assessed.This type is to occur in erosion on soil surface layer which is in bare state or no very good in vegetation coverage. Its distributive area is very large and the formative reasons are quite complex. According to the different aims and uses, the assessment for the soil surface erosion are divided into five phases. They are. (1)the assessment of potential hazard, (2)the assessment of actual risk, (3)the assessment of harm hazard, (4)the assessment of eroded present features.Methods for the assessments of cash of these phases are analysed in accordance with practical experiences and the information concerned.These methods can be used for assessment in different area and situation of different soil surface erosion. They can provide scientific basis for precentation and control of water and soil loss and for reasonable development of resources.
