摘    要:通过测定中国西南季风常绿阔叶林不同演替阶段(演替15a,演替30a及原始林)群落中植物叶片与土壤中C、N、P含量,探索了季风常绿阔叶林不同演替阶段群落C、N、P化学计量特征及其与物种丰富度及多度的相关性。结果表明:土壤及植物中全N、全P含量及土壤中C含量均为演替30a群落中最低,而植物中C含量在不同演替阶段群落间无显著性差异。在不同演替阶段共有种中,40%的物种N含量原始林中最高,40%的物种P含量演替15a群落中最高,而80%的物种C含量无显著性差异。土壤中C:N比在不同演替阶段间无显著变化,而N:P及C:P比则随演替呈减小趋势。植物中C:N及C:P比均为演替30a群落最高,而N:P比则随演替呈增加趋势。不同演替阶段共有种的C:N比中,40%的物种原始林中最低,40%的物种无差异,而C:P与N:P比中则均有60%物种无显著性差异,但70%物种在演替15a群落中N:P小于14,演替30a群落中50%物种N:P在14—16,原始林中则有80%物种N:P大于16。群落物种丰富度及个体多度均与C:N、N:P、C:P无显著的相关性,但植物中的N、P与土壤的N、P分别具有显著的线性正相关,说明土壤中N、P供应量影响植物体中的N、P含量。

关 键 词:演替阶段  相关性分析  化学计量  季风常绿阔叶林

Abstract:One of the principal insights of Darwin's theory of evolution by natural selection is the common descent of all organisms.Perhaps the strongest evidence for common descent is the shared underlying biochemistry based on nucleic acids,proteins,lipids,and other biomolecules.At the same time,natural selection has generated a plethora of morphologies,life history strategies and other differences that reflect variation in the way that organisms take up and transform energy and a variety of material elements.Ecolo...
Keywords:successional stages  correlation analysis  stoichiometry  monsoon evergreen broad-leaved forest
