摘要
Desertification indicates that the lands in arid,semi-arid and semi-humid arid are degenerated caused by climatic changes and mankind actvities etc.It is well known that the area of desertified lands in Xinjiang is the biggest,the most extensiv in distribution and seriously harmfull in China.There 80 counties and cities,nearly a half of the lands,about 10 million people,and more then 10 million mu (66700ha) farmlands in the region are being harmed by the desertification.Nature and human factors have aggravated the processes of desertification.The general development trend of desertification in Xinjiang is"extending entirely,contrary changing partially".In order to control the notable desertification,the result and causes,environment types,development trend,and classification of the land desertification in Xinjiang are discussed and the primary control measures of the desertification are put forward in the paper.
