摘要: 以土壤侵蚀发生规律为依据,从小流域系统的土壤抗蚀性、地质、地貌形态、植被覆盖、森林类型、土地利用等环境特征方面分析了影响官司河流域土壤侵蚀危险性的主导因素,运用模糊数学综合分析方法,将研究区域分为剧烈、强度、中度、轻度和无侵蚀危险类型,完成区域土壤侵蚀类型划分,并指出各种类型的特征和防治侵蚀的措施。

Abstract: Based on the fuzzy mathematics principles, the factors influencing soil erosion risk ie. soil antierosionness, geology, landforms, vegetation coverage, forest type, current landuse status et al, are analyzed. 5 erosion risk classes, ie. very strong, strong, medium, low and no erosion risk, ate divided out in this area. The characterstic of each class and erosion-preventing measures for each class are pointed out finaly in this paper.

Key words: SOIL EROSION, ASSSESSMENT, SOIL AND WATER CONSERVATION
