According to investigation results based on remote sensing technology

This paper discusses the patterns of Cele oasis desertification dynamic change in the south of Tarim Basin. Considering macroscopical research

this paper chooses 4 main land cover types which are desertification

oasis

Ecotone and water body

and they represent distinct characteristics of the local area. To register 3 different time

spatial resolution and spectral resolution satellite images

the paper uses some GCPs registered accurately 3 satellite images （for MSS

TM

SPOT HRV） and fuses a image with these multi

s

ource data. The fusion image shows more details than mono

t

ime image and plays a assistant revising role to some dynamic change charts as followings. On the basis of field survey and some statistical data

the paper uses PCI soft ware to process these data and produces a series of 4 main land cover dynamic change charts. Through analyzing these charts

the paper has studied the dynamicly distributed data of land covers spanning 21 years and the regulation of the local ecological environmental system. At last the paper points out that the trend of Cele region oasis desertification expansion is derived from two important reasons which have severe influences of nature and humanity. Therefore

in order to ameliorate the local ecological environment

people living in Cele country should work hard to plant more to preserve their homeland and reduce the degree of sandy wind offensive

to develop social economy

and to carry out sustaining development.
