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.
