The results indicate that:(1)Compare with the comparion, the soil physics character are improved after vegetation restortion , the soil unit weight in cyclobalanopsis glauca, Pinus elliottii, Robinia pseudoacacia , mixed forest and fire slash shrub separatly are 1.525g/cm~3, 1.426 g/cm~3, 1.625 g/cm~3, 1.482 g/cm~3, 1.423 g/cm~3. We can find the soil unit weight in other forest all bigger than the comparion (1.580 g/cm~3) except Robinia pseudoacacia .All these mean forest soil is looser and better capacity for aerated and dank.
结果表明：(1)植被恢复后林地土壤物理性质有良好的改进，青冈、湿地松、刺槐、混交林、火烧迹地灌丛容重分别为：1.525g/cm~3、1.426g/cm~3、1.625g/cm~3、1.482g/cm~3、1.423g/cm~3，除刺槐外其他林地均低于对照(1.580g/cm~3)，上述几种林分的孔隙度分别为：45.872%、51.956%、44.093%、50.485%、55.648%、47.228%，说明林地内土壤较对照更为疏松、通气透水能力更强，更有利于土壤微生物的活动，为研究区土壤肥力的提高奠定了基础。
