Influence of different strata lithology on soil erosion in Dafang County of Guizhou Province

Using software such as ArcGIS, ENVI, and SPSS, correlation between soil erosion intensity and different strata lithology was analyzed from a macro perspective．Studying influence of different strata lithology on spatial distribution of soil erosion can help to understand mechanism of soil erosion formation, and propose strategies for controlling erosion based on distribution of strata lithology with different levels of erosion intensity in different regions．This is of great significance for protection of agricultural resources．
