摘要
该文综合考虑了气候、水文、地貌、土壤、植被及土地利用等因素，以ＤＴＭ上的最小沟谷单元为侵蚀的基本单元，并把坡面侵蚀和沟谷侵蚀分别处理，提出了一种新的定量模型来计算黄土高原地区的土壤侵蚀。然后以陕西省府谷县为例，利用地理信息系统技术，对该模型参数的获取进行了探讨和验证。
Considering the factors of climate,hydrology,landforms,soil,vegetation and land u-tilization synthetically,handing the erosion of slope surface and ravine separately a new quanti-tative model is put out to calculate soil erosion in loess plateau by taking the minimum gully unit of DEM as the basic unit of soil erosion.Then taking the practice at Fugu county Shaanxiprovince for example the ecquisiton of model parameters is studied and tested with geographic information system(GIS)technology.
