摘要
在地理信息系统的支持下,采用通用土壤流失方程(USLE) 及其修改式估算了海南岛现实土壤侵蚀量和潜在土壤侵蚀量,分析了土壤侵蚀因子R,K,LS在海南岛的表现,得到了海南岛现实土壤侵蚀量和潜在土壤侵蚀量的空间分布特征。研究结果表明:中部山区的现实土壤侵蚀量和潜在土壤侵蚀量均较其它地区大。
Applying Geographic Information System (GIS) technology, and adopting Universal Soil Loss Equation (USLE), the potential soil losses and the reality soil losses in Hainan island was estimated, the soil erosion factors (R, K, LS) in Hainan island were analysed, the spatial distribution of soil erosion characteristics in Hainan island was presented. The result shows the potential and reality soil erosion in Hainan mid mountain area is serious.
