| 摘 要： | 本文在去年对库布齐沙漠银肯响沙湾沙粒特征与风选程度关系论证的基础上，进一步对响沙湾表层沙粒的水分含量和容重进行了测定，并对测定结果作出了相应的分析：在沙丘背风坡含水量、持水量平均值小于迎风坡含水量、持水量；沙丘迎风坡的容重大于背风的容重符合沙丘一般规律；沙样的轻矿物含量比我国其它沙漠轻矿物平均值多1．76％，而重矿物少1．76％。

| Abstract: | On the basis of study on particlesize characteristics and degree of selection by wind in Yinken soundingsand hill, Kubuqi Desert, determination on moisture content and volume weight of sand particle on the surface of soundingsand hill have been further done and relevant analysis has been done on the determination results. The average of moisture content and moisture capacity in lee dune are smaller than that in windward dune. The volume weight in windward dune is bigger than that in lee dune which conforms to general rule of dune. The content of light mineral in sand sample is higher than the average value in other desert in China by 1.76%, on the contrary, the content of heavy mineral is lower than that in other dune by 1.76%. |
