| 摘 要： | 根据杉木人工林连栽容易引起产量下降和地力衰退等问题，对杉木林采伐迹地采用火力楠、湿地松和马尾松进行更新对比试验，研究结果表明，以火力楠为更新树种形成的人工林生长快、蓄积量大，林下生物多样性丰富，土壤水分物理性质得到较大的改善，土壤肥力提高快。火力楠是杉木林采伐迹地更新较为理想的树种。

| Abstract: | The regeneration study to select Michelia macclurel,Pinus elliottii and Pinus massoniana in the harvest site of Cunninghamia lanceolata was carried out in order to solve the problem that the continuous plantation of Cunninghamia lanceolata caused the decreasing of productivity and soil fertility.Result shows that: the stand of Michelia macclurel,whose soil water-physical character and soil fertility are improved greatly,grow fast and the its undergrowth biodiversity are abundant.Michelia macclurel is one of... |
