| 摘 要： | 对26年生福建柏湿地松(1∶1)混交林、福建柏纯林的林分生长状况,林下植被生物多样性以及林下土壤的养分状况进行调查分析。结果表明:福建柏的树高、胸径、单株材积,混交林比纯林大12.6%、23.5%、63.8%,混交林总蓄积量比纯林大51.2%,经方差分析,差异显著;混交林和纯林林下植物丰富度一致,但均匀度和多样性指数混交林大于纯林;混交林土壤与纯林土壤相比,土壤结构较好,土层疏松透水,持水能力强,土壤肥力较高。

| Abstract: | This paper investigated the forest stand growth condition,biodiversity of understorey vegetation,and nutrient status of soil of mixed forest of Fokienia hodginsii with Pinus Elliottii and pure planted forest of Fokienia hodginsii.The result showed that the height,dbh,and tree volume of mixed forest of Fokienia hodginsii with Pinus elliottii was12.6%,23.5%,and 63.8% higher than that of pure forest of Fokienia hodginsi,and the total accumulation of the former forest was 51.2% higher than that of the latter forest.and species richness index and diversity index were both higher than those of pure forest of Fokienia hodginsi.The former forest had following features:good soil structure,porous soil,water holding capacity,and high soil fertility. |
