Abstract: The desert vegetation is of great significance in restraining the desert expansion, preventing the sandstorm invasion and protecting the oasis stability. In this paper, we obtained the high resolution NDVI data by the multispectral camera on a UAV The vegetation showed the seasonal changes and its growth was mainly constricted by precipitation in growing seasons, furthermore, the response of vegetation to precipitation and temperature had a certain lag effect.

Key words: Badain Jaran Desert, vegetation coverage, NDVI, UAV multispectral data
