| 摘 要： | 红鳞蒲桃（Syzygium hanceiMerr.et Perry）季雨林是广西海岸带的地带性植被类型之一,但是本区该类季雨林资源已非常有限。至2009年,广西滨海仅保留19.1hm2,在防城港市以村边＂风水林＂残存,其他地段已消失,偶见单株。在红鳞蒲桃群落1200m2的样地中,共有维管束植物97种,隶属40科75属。群落乔木层结构简单,无分层或分为2层,红鳞蒲桃占绝对优势。因受人畜影响大,红鳞蒲桃群落的物种多样性指数低,种群林下无幼苗和幼树,以中树和大树占优势,属衰退类型。各群落以低高度级和小胸径级的个体数占优势,但是红鳞蒲桃基本分布在最后2个级别里,随着演替的发展,它将逐渐从群落中衰退,被其他优势种取代。

| Abstract: | The Syzygium hancei seasonal rain forest is one of the zonal vegetation types along the coast of Guangxi.According to a investigation conducted in 2009,it was scarce now and only reserved as geomantic forests(about 19.1 hm2) beside villages in Fangchenggang city,meanwhile,some individuals occasionally appeared in other coastal areas.According to the investigations in the plots of 1200m2,97 plant species belonging to 40 families and 75 genera were recorded in the communities of S.hancei.The structure of the ... |
