Method and Practice of Remote Sensing Monitoring on Desertification Development
沙漠化遥感动态监测的方法与实践

Land desertification is a very serious environmental-economic problem in the North China.To carry out remote sensing monitoring is an effective measure for understanding the expanded processes,status and trends of desertification.Based on the formation of the interpretation indicator system and technological process,we advanced a method of remote sensing monitoring on desertification development and practised it in the Mu Us sandy Land.The results indicate that to depend on this method we can bring to light the distribu- tion of desertified land in time and space and their patterns of evaluation,which will pro- vide scientific basis for successfully combating desertification.
