摘　　要：本文对内蒙古大青山区阴坡中部油松人工林地土壤物理特性进行了研究,主要研究结果如下:林地土层厚度为35 cm^104 cm。林地土壤石砾含量表层为59.21%~71.88%;土壤A层为53.24%~79.83%,B层为47.35%~67.13%。林地土壤田间持水量、土壤容重和土壤总孔隙度的研究结果为:当林分密度为2 933株/hm2~3 307株/hm2时,其分别为23.60%~26.90%、1.21%~1.31%和53.16%~53.68%;当林分密度为2 202株/hm2和4 463株/hm2时,其分别为22.88%~23.04%、1.39%~1.42%和48.68%~49.37%。20 cm深土壤饱和导水率随着林分密度的增加呈降低趋势,而40 cm深土壤饱和导水率随着林分密度的增加呈上升趋势。The soil physical characteristics of Pinus tabulaeformis plantation were studied in the middle shady slope of Daqing Mountain.The results showed that: the thickness of the soil layer was 35~104cm.The soil gravel content was 59.21%～71.88% in surface layer,which was 53.24%～79.83% in A layer and 47.35%～67.13% in B layer.The field capacity,the volume weight and the soil total porosity was 23.60%～26.90%,1.21～1.31 and 53.16%～53.68% separately,when the density of plant was between 2933 stubs/hm2 and 3307 stubs/hm2...
