摘要: 福建中亚热带闽北部、闽中部两亚地带,气候条件与植被类型特征均有一定的差异,而其常绿阔叶林中占绝对优势的壳斗科树种的分布,具较明显的水平地带性规律。本文为进一步探讨其分布特点,据该地带12个县(市)的共69处调查样地、15000m2面积的壳斗科树种数据,采用调查县(市)间及其树种间的重要值相似性指数作聚类分析,将全地带壳斗科主要树种的分布划分为闽北部与闽中部两个区域类群。用调查县(市)及树种作极点排序表明,不同地理分布区各树种的数量和长势等特征反映出纬度与降水量呈显著正相关而与温度呈显著负相关。它显示出福建地理因素中的温度与降水量对树种分布的综合作用效果。树种分布的生态幅分析表明,全地带的甜槠等4个树种属于较均匀广布种,而苦槠、乌楣栲与米槠、赤枝栲等,分别属于该地带的闽北部与闽中部亚地带的区域代表种。

Abstract: Based on the data of species of Fagaceae, surveyed from 15, 000m2 of 69 plots in 12 counties and cities, in mid-subtropical evergreen broadleaved forests in northern and central Fujian Province, and of the agglomerative analysis between the similarity indexes of some counties and the different species of the family these species may be divided into two area groups, i.e. the northern Fujian area group and the central Fujian area group.According to the analysis of the different species of the family in the surveyed counties by the polar ordination method, it is clear that in the mid-subtropical zone of Fujian, they are not alike all the areas: altitute increases positively with rainfall and negatively with temperature. Therefore this shows the comprehensive effect of the geographic elements, (temperature and rainfall) on the ecological distribution of these species. Analysis of the ecological amplitudes among these trees indicates that Castanopsis eyrei, C. fargesii, C. fordii and Cyclobalanopsis glauca are broad-distribution species, but Castanopsis sclorophylla and C. jucunda are representative species of the northern Fujian area, and C. carlesii and C. kawakamii are representative species of the central Fujian area.
