| Abstract: | With interpreting image features,monitoring on land area of desertification and desertification degree was completed in the paper.On the basis,the authors analyzed the change trend of desertification in central Asia from 1989 to 2009.The results showed that the method used in the paper had an appropriate reliability and practicality,which could be utilized to monitor the dynamic change of desertification fast in a large scale. |
