Abstract:
With the accurate positioning technology of GPS, this paper applies the technology of remote sensing to the sensitive region, the Chaganhu conservation zone. Validated in the field with GPS, the land use/cover classification of twelve classes is extracted, and the main features of the environment changes are concluded. The results indicate that in the past 16 years from 1988 to 2004, the environment has deteriorated seriously. The area of water has decreased by 139.36 km2, the area of salty alkali soil has increased by 106.83 km2, and the area of absolute alkali land has increased by 107.21 km2. The authors make Preliminary analysis on the reason is made and some feasible suggestions to recover the environment is proposed.
