Abstract

Abstract: Ejin Banner,a typical natural oasis in the desert area,provide a natural green defence for Hexi Corridor.Investigating into the land use by remote sensing proved that the ecological environment of this area has been degraded seriously.The reasons of environmental change of arid area has been analysed in the studing of Ejin Banner which situated in arid area.The studing results suggested the necessity and urgency of ecological environmental protection.

Key words: Ejin Banner, Oasis, Environmental change, Influencing factors
