摘　　要：为了揭示信叶高速公路沿线湿地土壤状况,选择6个研究地并对其土壤物理因子进行分析。结果表明,在水平分布上,各研究地土壤含水量、容重、毛管孔隙度、非毛管孔隙度、粉粒及黏粒变化范围分别为16.83%~18.54%、1.15~1.40 g/cm3、28.47%~33.06%、5.40%~8.76%、47.13%~67.31%和18.43%~42.14%。在垂直分布上,多数研究地土壤含水量、容重上下层变化幅度小,随土壤纵向深度增加,各研究地土壤孔隙度和机械组成变化复杂,不同研究地的土壤含水量、非毛管孔隙度差异显著,容重、毛管孔隙度、粉粒、黏粒差异极显著;土壤层次对容重、粉粒、黏粒有显著影响,对含水量、毛管孔隙度、非毛管孔隙度无显著性影响。In order to reveal the soil conditions of Wetland along the Xinye expressway, 6 areas were selected and their soil physical factors were analyzed. The results indicated that in horizontal direction, the change ranges of soil moisture content,bulk density, capillary porosity, non-capillary porosity, and the contents of silt and clay were 16.83%~18.54%,1.15~1.40g/cm3, 28.47%~33.06%, 5.40%~8.76%, 47.13%~67.31%, and 18.43%~42.14% respectively. In the vertical direction, the soil moisture content and bulk density of many areas varied indistinctly, while the changes of soil porosity and mechanical composition were complicated. The differences of moisture content and non-capillary among the 6 areas were significant, meanwhile, the differences of bulk density, capillary porosity, and the contents of silt and clay among them were remarkably significant. The depth of soil had significant effects on the bulk density, the contents of silt and clay, but not on the moisture content, capillary porosity, and non-capillary porosity.
