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。

Our results showed 1 The changes in trends of leaf traits response to the rainfall gradient differed either with species or with a specific trait; 2）The same trends were found at the functional group level, However, leaf traits for grasses tends to be less sensitive, then for forbs, and the legumes is the most sensitive functional group along the rainfall gradient, indicated that the Grass function group is quite strong to the soil moisture content tolerance, and which certainly explained to the local vegetation distribution and the substitution between species.

主要结论如下：1 叶片性状在降雨量梯度上的变化趋势在物种水平上表现出多样化的特点，性状的变化趋势是否有显著的格局取决于物种或特定性状。2 叶片性状对水分梯度的响应在功能群水平上表现出各自的特点，Grass功能群对水分梯度的响应敏感性较低，Forb居中，Legume表现出较强的敏感性，表明Grass功能群对水分的耐受性比较强，这在一定程度上解释了当地克氏针茅草原上目前以禾草类为主的现状，对物种之间的替代有一定的指示性。
