| 摘 要： | 土地利用变化改变了原有地表植被类型、覆盖度和微地形,从而使区域土壤侵蚀特征发生变化.因而土地利用类型是土壤侵蚀强度划分的重要参考指标.选取2000年土地利用类型图与1995-2000年的土壤侵蚀图,借助ArcGIS软件技术分析了大别山区1995-2000年的不同土地利用类型的土壤侵蚀变化特征,揭示了区域土地利用/土地覆被变化的基本规律及其土壤侵蚀变化的基本过程,为区域水土流失治理的工程与技术措施提供依据.

| Abstract: | Landuse may change the original vegetation types and their coverage and micro-topography and thus affects soil erosion processes.Landuse type is an important indicator of soil erosion gradation.In this study,the characteristics of soil erosion under the different types of landuses in Dabie Mountain area from 1995 to 2000 are analyzed by selecting the 2000 landuse plan and the map of soil erosion types of 1995-2000 and using the software technique of ArcGIS.The basic features of regional landuse/land cover changes and the change processes of soil erosion under the different types of landuse change are revealed.Result from the study may provide a basis for soil erosion control projects and technical measures. |
