| 摘 要： | 通过对常绿阔叶林采伐迹地不同更新方式林地土壤肥力的比较研究，结果表明：采用人促天然更新形成的米槠单优群落林地具有良好的土壤结构性能与水分性状；土壤疏松多孔，具有较强的保水保肥能力，其土壤有机质和营养元素含量较为丰富；土壤酶活性较强，呼吸作用强度较大，表现出较强的自我调节能力和较高的土壤肥力水平。常绿阔叶林采伐后经炼山营造杉木人工林，土壤肥力则呈下降趋势。

| Abstract: | The comparative study results of the forest soil fertility through different reproductive modes on the evergreen broadleaved forest felling blank indicate that the forest land of Castanopsis carlesii consociation formed by the natural reproduction with artificial promotion possesses the good soil structure performance and water character;the soil is loose and porous and has the relatively strong water-holding and fertilizer-conserving capacity;the organic matter content and nutrient element content of the soil are comparatively rich;and the organic mater content of the surface layer(0～20cm) soil of C.carlesii forest is 0 7602% higher than that of Cunninghamia lanceolata plantation. |
