摘要： It is significantly important to study the topsoil aggregates occurrence for land use, recovery at regional scale and protecting from topsoil sandification. Based on land sampling through experimental analysis and correlation statistics, this paper studies on the characteristics and the correlation of different habitat topsoil aggregates in Mu Us region. The results show: The soil aggregates are mainly micro aggregates in the range of 0.5 similar to 0.25mm in this area. The contents of soil aggregates are different in different depths which are 0cm > 10cm > 20cm respectively. The contents of soil aggregates are also different in different habitats, and the contents of > 1mm soil aggregates are highest 4.27% and 3.55% in poplar woodland and Calamagrostisepigeios grassland sampled at the 0cm depth. After analyzing the stability of soil aggregates, the development of soil aggregates is not sufficient, and the stability of soil aggregates is poor. The soil structure is gradually optimized in the better area of vegetation protection or restoration.
