摘要
土壤侵蚀研究的一大核心问题就是土壤侵蚀量的估算。采用美国通用水土流失方程(USLE),利用黄土高原地区DEM数据、气象数据及土地利用类型等数据,对黄土高原地区进行土壤侵蚀量的估算采用USLE模型,运用GIS和RS技术,是一种可行的方法与技术途径。在GIS和RS技术的支持下,实现了USLE中各因子及黄土高原地区土壤侵蚀量的估算,同时结合中国土壤侵蚀强度分级标准进行土壤侵蚀强度的分级。分析结果可为今后黄土高原地区的水土流失的防治措施的制定提供参考。
Soil erosion estimations one of the core issues in research field of soil erosion. The American universal soil loss equation( USLE) was selected as the mathematical model. It is a feasible method and technical approach to estimate soil erosion in loess plateau area by USLE model and GIS and RS technology. By utilizing the DEM data of loess plateau area,the weather data from weather station,the information of land use and other related data,with supporting of GIS and RS technologies,the estimation on each factor of the USLE as well as the amount of soil erosion in loess plateau area was realized and the major influence factors of soil erosion was further analyzed.In the meantime,the soil erosion intensity of the area,was classified according to the classification standard of soil erosion intensity in China. The results could provide references for future development on control measures for preventing water loss and soil erosion in loess plateau area.
