| 摘 要： | 本文探讨了福建南靖县和溪的7处海拔220m以下的亚热带雨林样地的群落特征。据对其中典型的红栲、红鳞蒲桃群落的1200m2面积统计，有维管植物216种，分属于80科145属。其区系成分以樟科、大戟科、茜草科与紫金牛科等的属、种为主；包括泛热带、热带分布的热带性植物地理成分占总属数的80.0%。福建和溪亚热带雨林包括7个群落，分属3个群系，即1)红栲、红鳞蒲桃群系；2)米槠、红栲群系；3)红鳞蒲桃、厚壳桂群系。该雨林典型群落乔、灌木种的Shannon—Wiener多样性指数(D)=5.47，均匀度(J)=17.26%，以及对其树木年龄结构分析表明，该群落是相对稳定性较高的、可作为我国南亚热带的一个典型植被类型。

| Abstract: | The subtropical rainforests of Castanopsis hystrax, Syzygium hancei Formation etc. discussed in this paper are located in the Hexi area (24?56′N, 117?14′E) of Nanjing County, Fujian Province on the north bound of the southern subtropical region in China.According to the survey of 12 plots totalling 1200m2 in the Liudao mountain of Hexi area, the floristic composition consists of 210 species of vasscular plants of 145 genera and 80 families. Analysis of the floristic geographical elements indicated that the percentage of tropical and pan-tropical elements (such as the species of Lauraceae, Myrtaceae, Rubiaceae and Myrsinaceae, etc.) is high, making up 80 % of the total genera.The Hexi subtropical rain forests consist of 7 associations in 3 formations, i. e. (1)Castanopsis hystrix, Syzygium hancei Formation (2) Castanopsis carlesii, C. hystrix Formation and ( 3 ) Syzygium hancei, Cryptocarya chinensis Formation.The evenness (J) and Shannon-Wiener′s index of species diversity (D) of the Hexi subtropical rain forests are 17.26% and 5.47 respectively. The analysis of age structure of the trees in the forests showed that the community is of relative stability, so the communities are one of zonal vegetation types of the southern subtropical region in China. |
