中文摘要	采集了沙漠-黄土南北样带从北到南的沙漠区、过渡区、黄土区的土壤样品,测量和分析了不同区域土壤容重(D)、粒度特征。结果表明:①D_(沙漠区)>D_(过渡区)>D_(黄土区),土壤容重的平均值依次为1.53g.cm~(-3)、1.51g.cm~(-3)、1.41g.cm~(-3),过渡性明显;②沙漠区以中砂和细砂为主,过渡区以细砂为主,黄土区以细砂和粉砂为主。从沙漠区到黄土区,土壤颗粒逐渐变细,粘粒含量增加,分选性变差,偏度均属正偏,且在增大,峰态从常峰态向窄峰态类型变化,过渡区和黄土区属于双峰态,沙漠区属于单峰态。
英文摘要	Through collecting the soil samples from desert area,desert-loss transitional area,and loss area, which are located in a meridional desert-loess transition zone in north Loess Plateau,we analyzed the soil bulk density and grain-size.The results showed that:(1)D_(desert)>D_(desert-loss)>D_(loss),and the average soil bulk densities were 1.53 g.cm~(-3),1.51 g.cm~(-3),1.41 g.cm~(-3) for the three sub-areas,respectively,which had a transitional trend.(2)Medium and fine sand were higher in the desert area,fine sand was higher in the desert-loess transitional zone,while fine and silty sand were higher in the loess area.From the desert area to the loess area,the soil grain size became smaller;the content of clay particle increased;the sorting gets worse;the skewness belonged to a right skewness but having an increasing trend;the kurtosis changed from mesokurtic to leptokurtic.It was single-kurtosis in the desert area,and it is double-kurtosis in the transitional zone and loess zone.
