中文摘要	采用空间代替时间的方法,对毛乌素沙地东南缘沙漠化过程中土壤理化性质变化进行了分析. 结果表明,沙漠化过程中土壤理化性质呈规律性变化,随沙漠化程度的加剧,土壤黏粒含量、含水量、有机质、有机碳和全氮含量减少,土壤砂粒含量、容重和C/N增加,土壤质量下降;相关性分析结果表明,容重和C/N比与各指标呈负相关关系,其余各指标间呈正相关关系,其中容重与有机质、全氮含量之间以及有机质与全氮含量之间存在极显著相关性,黏粒含量与含水量、容重、有机质和全氮含量之间存在显著相关性,含水量与容重、有机质和全氮含量之间也存在显著相关性,说明沙漠化过程中土壤各组分之间存在着密切的内在联系
英文摘要	By the methodology of "The Temporal for The Spatial", the changes of soil physical and chemical properties on the southeastern edge of Mu Us sandy land were studied. Results showed that soil physical and chemical properties changed regularly in the process of desertification. With the increased degree of desertification, the contents of soil clay, soil water, organic matter, organic carbon, and total nitrogen decreased, while the content of soil sand, soil bulk density, and C/N increased. With the increased depth, the content of soil water and soil bulk density increased and the contents of organic matter, organic carbon, and total nitrogen decreased, while C/N increased firstly and decreased later. Results of correlation analysis showed that the correlations of soil bulk density or C/N ratio with other indicators were negative, while the correlations of other indicators were positive. The negative correlations of soil bulk density with the content of organic matter and total nitrogen were significant at the level of P
