| 摘 要： | 固定沙丘、半固定沙丘、流动沙丘、甸子地等不同地貌的相间分布是科尔沁沙地的主要地貌特征之一。在这种特殊的坨甸相间地貌中，土壤水分的空间分布必定有其特殊性。在科尔沁沙地坨甸相间地区的各种地貌类型区进行了土壤层及植被根系层水分状况的实地调查及室内实验。基于实验结果分析出沙地固定沙丘、半固定沙丘、流动沙丘、甸子地不同地貌类型的土壤水分的空间变异特性，并结合四种不同地貌类型区的土壤水分空间分布特征，按照表层、中间层和底层进一步对比分析了不同地貌土壤水分的变化和分布，这对于了解科尔沁沙地土壤水分的变化规律及其与地貌类型的关系，具有一定的意义。

| Abstract: | In Horqin sandy land,the distribution of fixed dunes,semi-fixed dunes,moving dunes and marshland is alternate.The spatial characteristics of soil water are particular in the special marshland-dune areas.In this paper,field survey and laboratory experiment were conducted to study the soil moisture variation in different landforms.The spatial differentiation characteristics of soil moisture in fixed dunes,semi-fixed dunes,moving dunes and marshland have been got and compared,and their stratigraphic maps were obtained based on soil moisture dynamics.The study has significance to open out the variation rules of soil water and the relation with landforms in Horqin sandy land. |
