摘要
根据通用土壤流失方程的基本原理,结合福建省的自然环境特征,选择降雨侵蚀力、地形起伏度、土壤质地、植被类型4个自然因子作为评价指标,在G IS软件支持下对福建省土壤侵蚀敏感性进行评价,评价结果综合反映了福建省土壤侵蚀敏感性的分布规律,为土壤侵蚀防治、生态环境保护与建设以及土地资源合理开发利用提供依据.
Based on Universal Soil Loss Equation (USLE) and the natural environment characteristics of Fujian Province, four natural factors affecting soil erosion were chosen as the assessment indices, which are the rainfall erosivity, relief, soll texture and vegetation types, and the soil erosion sensitivity of Fujian Province was assessed under the support of GIS. The assessment results reflect the distribution law of the soil erosion sensitivity in Fujian Province.
