以库布齐沙漠南缘典型抛物线沙丘为研究对象，通过对沙丘土壤水分含量与紧实度的测量，分析了沙丘形态特征与土壤水分含量、紧实度的关系。结果表明，沙丘臂间平地水分含量与其周围本底值相似，高于沙丘其它地貌部位。沙丘土壤水分含量高的区域，紧实度较大，抗侵蚀能力较强。沙丘土壤水分含量、紧实度等物理性状特征也影响植被的发育与分布。

Choosing a typical parabolic dune in the south of Hobq Desert, by measuring moisrture content and soil compaction and analyzing the relationship between dune morphology and soil water content, degree of compaction, in order to define the factors of morphological development of parabolic dunes and their interactions. The result shows that the soil moisture content of flat between arms is similar to surroundings and higher than other positions. For someplace, it is the higher moisture, the higher compaction also stronger anti-erosion ability. Physical properties of soil such as moisture and compaction also impact vegetation planting.
