天然格氏栲林皆伐火烧后栽建柏林区系组成变化研究

Comparative Study of Flora on Castanopsis kawakamii Forest and Fokienia hodginsii Plantation Planted after the Former Cut and Burned

通过设置临时标准地，对福建天然格氏栲林皆伐火烧人工栽培３２年生建柏林和格氏栲自然保护区天然格氏栲进行植物区系组成的研究结果表明：建柏人工林和天然格氏林共有科、属、种分别占建柏林总科数８６％、总属数８６％、总种数９３％；属的分布型分析，建柏人工林和天然格氏栲林都以热带成分为主，但建柏人工林热带成分略高于格氏栲天然林；种的分布型分析，建柏人工林和天然格氏栲林都与广东、广东同类型区系共有种的百分比也较高．

Comparative analyses on flora of natural Castanopsis kawakamii forest and Fokienia hodginsii plantation Planted after the former cut and burned had been made in this paper.According to statistics,the common families,genera and species occur in two stands are 86%,86% and 93% of those in Fokienia hodginsii stand respectively.The analyses of generic arealtypes showed that most genera are the tropical.And the analyses of shoes areal-types indicated that the flora of the two communities is more closely related to that of Guangdong.
