Research on Geographic Environment and Area Evolution of Lake Ulungur Region Based on 3S Technology

摘要

This research used remote sensing image data to abstract archaeological site of lacustrine deposit in Lake Ulungur. Meanwhile, the ancient lake area about 30000-50000 years was reverted, by using global positioning system, spatial analytical method and digital elevation model. On the basis of this, by doing the research on the distribution of the modern vegetation, this essay analyzed the relations between degradation and environment of the lake.
