Abstract：In order to probe into development and reasons of sandy desertification in Otindag Sandy Land in recent 40 years, development characteristics of sandy desertification of this area in recent 20 years were analyzed from the view point of vegetation cover rate changing based on the newest remote sensing data. Then natural and human factors affecting sandy desertification were analyzed according to the meteorological documentary data from a lot of meteorological observation and the social statistic data of studied area. It was showed that the climate of this area took on the trend of warming and moistening, which was beneficial to the converse development of desertification and that the irrational economic activities of human were the primary factor leading to sandy desertification during the last several decades.
