GIS-based Soil Erosion-prone Evaluation Of Highway Domain

摘要：

In order to predict the macro trend of soil and water loss within highway domain, the problem of soil erosion is studied. Used the pressure-state-response model and expert advice method, four factors, such as slope, slope length, vegetation coverage, rainfall were selected. The indexes were treated with dimension method, calculated the weight of evaluation indexes on the basis of entropy theory. Then, set up the soil and water loss-prone evaluation model of highway domain. Based on GIS and RS, analyzed the status of soil and water loss of highway domain in Qinghai Province. Used MATLAB tools, calculated the entropy of each indexs value and the entropy weight, and established the thematic map, finished the quantitative analysis of soil and water loss-prone evaluation.
