Abstract

The Horqin Sandy Land (HSL) falls in the interlocking agricultural and pastoral zones in northern China. The sandy area experiences wind and water erosion and the evolution of lakes and landcover is closely related to changes to the sandy land surface. This study applied geomorphological analysis and mathematical and statistical analyses to multiple sources of remote sensing data to study the characteristics and changes in landforms, lakes, and lan cover patterns in the area. The results showed that the area of sandy land in the HSL has decreased over the last 40 years at an average rate of -0.31%, whereas the areas of fixed and semi-fixed sand dunes, such as scrub dunes and parabolic dunes, are increasing. The area of lakes and the number of patches have decreased, there was increased clustering of lakes, and the changes to the landscape appear to be stabilizing. There was an increase in vegetation growth, with mean annual average Normalized Difference Vegetation Index (NDVI) of between 1.42–2.06. There was an obvious increase in NDVI, mainly in the southeastern part of the study area. The study provides a basis for the sustainable development of the ecological environment in the HSL.
