  • Title: Change detection of sandy land areas in Minfeng oasis of Xinjiang, China.
    Author: Nasierding N, Zhang Y.
    Journal: Environ Monit Assess; 2009 Apr; 151(1-4):189-96. PubMed ID: 18373207.
    Abstract:
    In recent years, much attention has been given to desertification in Xinjiang, China, particularly in the southern edge of the Taklimakan Desert. In this study, an oasis in Minfeng County, which is located in the southern edges of the Taklimakan Desert, was chosen as our case study area. Supervised classification for land types was conducted, and then the change detection and the trend of changes in sandy land areas were analyzed and compared. The results show that the area of sandy land has decreased in the region in the period of 1992-2001. The main change was between sandy land and sparse vegetation in the Desert-oasis ecotone. In addition, the change from woodland to grassland and/or arable land was quite obvious from 1992 to 2001. These changes would probably result in more fragile environment and higher potentiality in land desertification in the area.
