Abstract

Based on the TM and ETM+ Lands at image data of 2000-2014, using the GIS spatial analysis method and visual interpretation methods, we extract the dynamic desertification information of Hulunbeier sand land. The spatial-temporal evolution characteristics of landscape pattern are analyzed on the foundation of desertification information. The results indicated that: (1) The total desertification land area decreased by 2822.59km2 in Hulunbeier during 2000-2014, and different levels of desertification land area has a reverse trend after 2010, which showed that the environment has improved. (2) During 2000-2014, the center of low desertification land moved 13.58km to South, medium and severe desertification land moved 10.99km and 27.57km to East, respectively, and high desertification land 24.17 km to northward. (3)In the period of 2010-2014, the intervention effect of humanactivities on the landscape is constantly enhanced, and the composition tends to simple, while the landscape type to uneven orientation development. The Landscape patch shape tended to regulation, and the desertification distribution tends to gather after 2010.
