| Abstract: | With Qiaozigou watershed in Tianshui city,Gansu Province as the research area,the soil loss equation(USLE model) which is in common use in the U.S.A. is adopted as the appraisal model,joining the spatiais analyst function of geographical information system(GIS),using GIS software Arcview to carry on estimation and analysis on the soil erosion intensity of the watershed,thus it offers scientific basis for evaluation of the ecological environment effect and soil and water conservation vegetation construction of the western region in our country. |
