Abstract:

Based on images in 2003,2008 and 2014,adopting remote sensing interpretation and the field investigation of landcover,combined with local climate,ecological engineering and other relative information,we analyzed the distribution of desertification land and dynamic changes in the middle area of the Kubuqi desert and tried to find the causes of the change.The results showed that:the aggravating trend of desertification is restrained and the area of desertification land is reduced by an average of 126 hectares in the study area in recent 10 years.The desertification degree index decreased from 0.568 in 2003 to 0.504 in 2014.The comprehensive dynamic degree of desertification land was 0.74% in 2003—2008 and increased to 3% in 2008—2014.That state of desertification land belongs to a slow change in the study area,but slow change rate in speed.Human factors were the main driving force on the dynamic change of desertification land.The measures of sand prevention and ecological construction were the major driving force to slow down and restrain land desertification.

Key words: Kubuqi Desert, desertification, desertification land, dynamic change, driving forces
