摘要
采用群落生态学的方法对闽西常绿阔叶林植被的1.6 hm2样地调查统计、分析,结果表明,构成闽西常绿阔叶林群落的优势科是樟科、壳斗科、木兰科、紫金牛科和山茶科等;闽西常绿阔叶林群落的植物区系具有明显的热带、亚热带地理性质;闽西常绿阔叶林群落的建群树种多,且部分不同的建群种间可组合构成不同的群丛,群落类型呈现多样化;闽西常绿阔叶林群落的外貌以单叶、革质、全缘和中小型叶为主的常绿中、小高位芽植物组成为特征;闽西常绿阔叶林群落植物在物种组成数量、科属分布区类型和生活型谱以及叶的性质特征等方面具有中亚热带南部向南亚热带过渡的特点。
On the base of 1.6 hm^2 cumulative sampling plots community ecological investigation of the evergreen broad-leaved forest in Minxi, and through species composition, areal types, life form spectra, and leaf character statistics analysis, The results showed, 116 families, 235 genera and 398 species of vascular plants were recorded; The dominant seed plant families of the evergreen breadleaved forest community in Minxi were Lauraceae, Fagaceae, Magnoliaceae, Myrsinaceae, Theaceae, and so on; The flora of the evergreen broad-leaved forest community was obviously tropical and subtropical geographical character in Minxi; The constructive species of the evergreen broad-leaved forest community was abundant, and different community form could be come into being by some constructive species combination which made community diversification; The evergreen broad-leaved forest community was characterized by the evergreen mesophanerophytes and microphanerophytes with simple leathery, entire mesophyllous and microphyllous leaves in Minxi; Comparison of the evergreen broad-leaved forest among Minxi and other regions, the community of the evergreen broad-leaved forest in Minxi had a transitional characteristics from typical subtropical flora to south subtropical at species composition, area type and life form spectrum, as well as the leaf character aspect.
