| 摘 要： | 对我国北方草甸草原（CD）、典型草原（DD）、荒漠草原（HD）生态系统的土壤物理性状进行研究．我国草原类型从东到西分别为草甸草原、典型草原和荒漠草原，结果表明其土壤容重逐渐增加，孔隙度逐渐减小．荒漠草原土壤砂粒含量最大，大于典型草原和草甸草原．方差分析表明，三种类型草原土壤容重、孔隙度和黏粒含量之间差异极显著．

| Abstract: | The soil physical properties of ecosystem of meadow steppe （CD）, typical steppe （DD）, and desert grassland （HD） of northern China are researched. The results show that the soil bulk density increases and porosity decreases. The desert grassland has the maximum sand content in soil of the three. Analysis of variance shows that there are significant differences between the soil bulk density, porosity, and clay content of the three types of grassland. |
