Abstract: Through the remote sensing monitoring of the representative region in Hunshandake Sandy Land, the authors interpreted the SPOT5 remote sensing image of 2003 and 2012 by ArcGIS 9.3, and the land-use type, vegetation coverage, desertification type and degree were analyzed by the quantitative method and qualitative method. The results showed that after 10 years ecological treatment, the vegetation coverage increased by 7.3% and the regional forest coverage increased by 6.9%. The ecological protection system was preliminarily formed and the ecological environment was improved significantly. But the phenomena of overgrazing and bringing wasteland into cultivation still existed in local region. The regional ecological condition presented a trend of integral-containment, regional improvement and local deterioration, the regional ecological construction was in the vital stage between governance and destruction.
