摘要
借助Arcgis、ENVI、SPSS等软件,从宏观角度分析了土壤侵蚀强度与不同地层岩性之间的相关关系.研究不同地层岩性对土壤侵蚀空间分布的影响可以掌握土壤侵蚀形成机制,从而针对不同区域侵蚀强度等级的地层岩性分布情况提出治理侵蚀的对策,对农业资源的保护具有重要意义.
Abstract
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.
