甜槠

甜槠林是古田山自然保护区常绿阔叶林主要类型之一。

Castanopsis eyrei forest was one of the main forest types in Gutianshan Nature reserve .

结果表明，甜槠林主要植物种群的空间分布均呈聚集分布。

The result shows that the space distributions of main plant communities in Castanopsis eyrei forest all appear the aggregating distribution .

海拔800～1300m山地以温性针叶林、甜槠木荷林等为主；

Castanopsis fargesii , at the altitude of 800 ~ 1300 m temperature-coniferous forest and Form .

而影响甜槠优势度的首要土壤营养元素为有机质、全氮、碱解氮、全磷。

That influencing that of Castanopsis eyre were organic matter , total nitrogen , available nitrogen , total phosphorus .

采用定量分析方法，计测天然甜槠林主要乔木树种的生态位宽度、生态位相似比例和生态位重叠值。

Quantitative analysis method was used to determine the niche breadth , the proportion of niche similarity and the niche overlap value of main arbor species of C.

结果表明，甜槠及其伴生树种的相对优势度分别为59.79%和40.21%，说明未来甜槠林仍由甜槠及其伴生树种共优组成，甜槠将支配整个群落。

The result shows that when reaching balance , the relative dominance of the Castanopsis eyrei ( Champ . ) Tutch . and its associated species are 59.79 % and 40.21 % respectively .
