| 摘 要： | 对建瓯市房道镇潘坑村毛竹混交林中19个主要乔木伴生种群的生态位特征进行分析。结果表明,重要值较大的毛竹伴生种群杉木、枫香、拟赤杨及栲树等对生境的适应性强,其生态位宽度较大;油柿与华杜英作为伴生树种出现的数量较少,生态位宽度最小;猴欢喜、五裂槭、毛八角枫、南岭黄檀的生态位宽度值比较相近,在群落内有类似的分布幅度,对资源的要求比较相近。粗糠柴与油柿、毛八角枫与华杜英、朴树与油柿、锥栗与福建山樱花之间具有较大的生态位重叠指数,说明相同或相似的环境要求的物种间生态位重叠较大;宽生态位种与其它种群的生态位重叠机会大;反之则小。杉木在混交林中分布较广,宽度值最大,但除与合欢、栲树及枫香有较高重叠外,与其它种群重叠较小,这说明具有较大生态位宽度的种群与其它种群之间的生态位重叠并不一定较高。

| Abstract: | Niche characteristics of 19 main associated tree populations in Phyllostachys heterocycla 'Pubescens' natural mixed forest in Pan-Keng Village,Fang-Dao Town,Jian′ou City were investigated.It was proved that associated tree populations of Cunninghamia lanceolata,Liquidambar formosana,Alniphyllum fortunei,Castanopsis fargesii with high important values had great capacity of adapting to circumstances and also had broader niche breadth;Diospyros oleifera and Elaeocarpus chinensis seldom appeared as associated trees and had narrow niche breadth;Cerbera manghas,Acer truncatum,Alangium kurizii and Pteroceltis tatarinowii had close niche breadth and had similar distribution range in tree population and have similar demand to resources.Mallotus philippinensis and Diospyros oleifera,Alangium kurizii and Elaeocarpus sylvestris,Celtis tetrandra and Diospyros oleifera,Castanea mollissima and Prunus campanulata had high niche overlap indexes which proved species having similar or same circumstances demands had high niche overlap indexes.Species with broader niches had more chances for niche overlap with other species.Cunninghamia lanceolata was widely distributed in natural mixed forest and had broad niche breadth but low overlap index with other species except Albizia julibrissin,Castanopsis fargesii and Alniphyllum fortunei,which indicated that species with broad niche breadth was not inevitable to have broad niche overlap breadth with other species. |
