- Abstract:
-
The changes of the area of Dalainur, one of the key lakes in Otintag Sandy Land, were analyzed in this paper based on remote sensing technology. The results show that the information about the lake and its changes in area of water body can be achieved quickly and conveniently by the method of single near infrared grayscale threshold. Satellite images of remote sensing, acquired by Landsat in 1975, 1989, 2001 and 2008, presented that Dalainur had been shrinking since 1975. Especially with the advent of the 21st century, the lake began to change significantly on all sides. Lakes shrinking and drying up are the important environmental issue that human has to cope with seriously. Under the pressure from global warming and population growth, the lake and wetland protection in Otintag Sandy Land and its local eco-environment sustainable development will face the greater challenges.
