【摘要】 依据水利部颁布的《土壤侵蚀分类分级标准》(SL190-96),采用第二次全国土壤侵蚀遥感调查中的多因素综合法,利用QuickBird遥感影像和DEM作为数据源,选取非耕地植被覆盖度、坡耕地和坡度3个因子,利用GIS和遥感技术,对保德矿区土壤侵蚀强度进行了评价,揭示了不同强度土壤侵蚀在空间上的分异,并简要分析了不同强度土壤侵蚀形成的原因。更多还原

【Abstract】 This study based on Soil Erosion Classification Grade Criteria(SL 19096) issued by the ministry of water resources and the multifactor comprehensive method in the second national soil erosion investigation.QuickBird remote sensing image and DEM were used for data origin in this study.Soil erosion intensity in Baode mining area was assessed by three factors of vegetation coverage,farmland in slope and slope selected as assessing indices.GIS and remote sensing technology were employed in this study.The space distribution of soil erosion intensity in different degree and reason of this distribution were also showed in this paper.更多还原
