- 摘要:
- 为了促进生态系统的养分循环、能量流动和保持森林生态系统平衡，通过设立样地调查广西罗城马尾松人工林的丰富度和生物量。结果表明:共记录马尾松林下植物种类34种，隶属于26科31属。生活型以高位芽植物为主。马尾松幼龄林林下植被丰富度与其生物量间存在很好的正相关性，相关系数（R2)为0.853 5，中龄林和近熟林的相关系数分别为0.569 2和0.3341。
- Abstract:
- In order to promote the nutrient cycling and energy flow of ecosystem and keep the balance of forest ecosystem，through the establishment of sampling plots of masson pine(Pinus massoniana)plantation,the species richness and biomass of understory were studied in Luocheng of Guangxi.The results showed that 34 species were recorded belonging to 26 families and representing 31 generas.Macrophanerophytes dominated the vegetation communities in the ecosystem.Species richness was positively correlated with understory biomass in young masson pine forest,R2=0.853 5,and correlation coefficient R2 were 0.853 5 and 0.334 1 respectively in half-mature forest and near-mature forest.
