基于GIS和RS的红壤丘陵区土壤侵蚀敏感性评价研究
Study on Soil Erosion Sensitivity of Red Soil Covered Hilly Regions Based on GIS and RS Technology
摘要
Abstract
The typical frail ecosystem - the red soil covered hilly regions of Southern China was selected as the study area. The Universal Soil Loss Equation (USLE) was used to study the soil erosion sensitivity in Gaoming Region based on GIS and high-resolution remote sensing technology. The annual soil erosion in Gaoming reached 6 757. 34 t/( km2 ·a) .belonging to the serious erosion regions. The soil erosion sensitivities of southern,northern,western and central hilly regions in Gaoming were extremely high,while the soil erosion sensitivities in eastern plains were lower. The hilly regions where the incline degree was larger than 7 -15° were the major serious soil erosion sensitivity regions. High soil erosion sensitivity areas mainly distributed in the fields or economical forestry. However, large incline degree areas were mainly dominated by high soil erosion sensitivities and moderate soil erosion sensitivities. Grasslands,shrubs,Eucalyptus forest,bare grounds and other land types were the major high soil erosion land types.关键词
