A PRELIMINARY STUDY OF CHANGES IN SOIL PROPERTIES OF THE DESERTIFIED LAND CAUSED BY ENCLOSURE IN THE SOUTHERN PART OF THE ZHELIMU LEAGUS,IN NEI MONGOL AUTONOMOUS REGION

Xu Bin(Desert Research Institute,Academia Sinica)  
Tests and analysis of samples in the desertified sandy land andsand dunes of internal(without any human disturbance)and externalenclosure in fenced and unfenced areas were carried out,and at thesame time,soil density and soil moisture in the fixed and shiftedsand dunes were determined in the fields in the southern part ofthe Zhelimu League,in Nei Mongol Autonomous Region.The con-clusions of physical and chemical soil properties in the desertifiedsand land in fenced area are as follows:(1)After the deserfifiedland is fenced,soil moisture tends to decrease.Soil particles in thesurface layer become fine,and soil bulk density decreases.(2)Af-ter the desertified land is fenced,the organic matter contents insurface layer and the whole N increase distinctly,and so does thecarnonate of lime formed in the,crust.The process of de-aluminimu andde-iron occur to some different extents in the middle and lower partsof soil profiles.
