黄果厚壳桂种群生态学特征

The ecological characteristics of Cryptocarya concinna population

通过对黄果厚壳桂的生态学特征研究表明，黄果厚壳桂是南亚热带季风常绿阔叶林中生性顶极群落中的优势种群，在南亚热带低山区域有广泛的分布。在森林群落演替的过程中，黄果厚壳桂是最早进入群落的中生性树种之一。其具有较高的光合速率和摄取营养物质的能力，一旦获得适应的生境，其生物量和第一生产力将在群落中占较大比重；黄果厚壳桂种群为优势种组成的生态系统内小气候相对稳定，各生理、生态特性差异较小；黄果厚壳桂是地带性植物群落的建群种和优势种，在维持群落结构的稳定性方面有重要的作用。

Cryptocarya concinna is a dominant population in the zonal vegetation of south sub tropic evergreen forest.It appears in an extensive distribution in the low subtropical hills Cryptocarya concinna is a mesophytes which is early one to entry the succession community in a successional process.It has a higher photosynthesis rate,and it can develop rapidly when it got a fit site.The biomass and productivity of Cryptocarya concinna population are big in its community.It takes part in a very important position on the stability of the community structure and function.
