摘要
土壤侵蚀是引起土地退化和河流泥沙淤积的根源,其产生与各种自然因素和人类活动存在一定关系。利用ArcView3.2和ARC/INFO8.1软件,通过图层叠加,统计分析和缓冲区分析等,对云南澜沧江流域的土壤侵蚀与地形坡度、土地利用/土地覆被现状、土壤类型和分布以及河流、道路两侧的缓冲区等之间的关系进行了分析。
Soil erosion can result in land degradation and sediment deposition of a river, where .soil erosion is connected with .some natural factors and human activities. Using ArcView 3.2 and Arc/Info 8.1 as the work platform, relations between .soil erosion and terrain slope, between .soil erosion and land use/land cover, between .soil erosion and soil types of Lancang river basin in Yunnan Province are analyzed according to the results of map layers intersection and statistics analyzing. Finally, soil erosion of 1 km wide buffers of river and road in the .same area is also studied.
