摘要
以内蒙古准格尔旗为例 ,利用 TM图像及相关辅助数据 ,通过 GIS软件 ARC/INFO、遥感软件 ERDAS IMAGINE 8.5 ,对影像进行格式转换、人机交互解译等处理 ,得到准格尔旗土壤侵蚀的结果数据。结果表明 ,准格尔旗风力侵蚀 ,水力侵蚀总体上仍比较严重 ,且以水力侵蚀为主。水力侵蚀与风力侵蚀强度侵蚀以上所占比例分别为 68.39%和 48.45 %。
Satellite remote sensing has become one of the important tools to survey land erosion. Take Zhungeer county as an example, depend on remote sensing images and other data, utilizing GIS software contained ARC/INFO and remote sensing software ERDAS, after disposition, transition of pattern and query, interpretation, the study achieve the soil erosion data of the area. The result shows that in Zhungeer county the hydraulic and eolian soil erosion of is serious and the hydraulic soil erosion is dominant. Waterpower and wind power erosion accounting for 68.39% and 48.45% respectively. So constructing protective forest and returning land for farming to forest and grass are the key measures to prevent soil erosion.
