Systematic Dynamic Mapping and Analysis of Small Basin Erosion Environment Based on Aerial Remote Sensing Information
利用航空遥感信息进行小流域侵蚀环境系列动态制图与分析——以山西省离石县王家沟流域为例

On the basis of application of aerial remote sensing information to erosion environmental systematic mapping of valley and gully area on loess plateau, an extensive study on loess erosion environment changes has been made in this paper. By using the different period aerial-photos of Wang Jia Gou, a small basin, which located in Li Shi county, Shanxi province, and by using the advanced geographical information system software ARc/INFO system, we have compiled the erosion environmental systematic maps of different periods and of different types: multiple factors erosion map, erosion amount distribution map, basin's valley and gully shape change map, average erosion developing speed map and basin multiple management evaluation map. On the basis of above works, we have made an analysis of erosion situation and environment changes in this small basin in different period by using environmental dynamic analysis method. Many-impacts, especially, the human impacts has been emphasized in the erosion environmental analysis.The results of this work has provided a scientific basis for multiple management for small basin on Loess plateau.
