Abstract  

The ecological pattern of the Ebinur Lake basin is the result of interaction between oasification and desertification processes. In this paper, satellite remote sensing data in three period (1990, 2001 and 2005) were taken as the basic data sources, and then ArcGIS was used to extract oasis and desert classification information. With the support of GIS techniques, the spatial-temporal change of oasis and desert in the Ebinur Lake basin from 1990 to 2005 were analyzed by change detection model, and then the oasis and desert barycenters were calculated. The results showed that: (1) From 1990 to 2005, the area of oasis increased, and the desert area decreased. The shrinking area of oasis was 1 853.75 km2, and the expanding area of oasis was 1 912.13 km2. (2) The spatial change of oasis was great, oasis expanding area was in the west of the Ebinur Lake basin and around the Ebinur Lake, and oasis shrinking area was mainly in the south-east of the Ebinur Lake basin. (3) The oasis barycenter transfer direction was south-west from 1990 to 2005, and the transfer distance was 3.4196 km, at the same time the desert barycenter transfer direction was north-east, the transfer distance was 6.9999 km.

Key words:  Ebinur Lake basin      oasis      desert      spatial-temporal change
