福州长安山森林公园植物群落物种多样性研究

Plant Community and Species Diversity in the Changanshan Forest Park of Fuzhou

以福州长安山森林公园为研究对象,对该区域的乔灌草进行详细地调查,并对植物群落的空间分布、多样性水平以及物种关联度、林层动态进行研究分析。研究结果表明:1)草本层的植物分布最均匀,其次是乔木层,而灌木层植物的分布相对较不均匀;2)灌木层的物种最丰富、生物多样性也相对最丰富,其次是乔木层和草本层,但种间关联性差;3)更新层的树种数量相对较少,并且树种较为单一,将不利于森林的发展,演替层的树种丰富而且数量多,有利于成为森林。研究认为:长安山森林公园种间关联性差,处于初级演替阶段,需进行进一步的改造。

The space distribution, species diversity, species association degree and forest floor dynamics in Changan Forest Park of Fuzhou were studied and analyzed through field investigation and statistics. The results showed that ： （1） the herb layer has the most uniform distribution, and the second one is tree layer, while the last one is shrub layer; （2 ） the species of shrub layer possesses the most diversity of species and community, and then is the tree and herb layer. But the correlation between species is poor. ; （ 3 ） the num-ber of species in the regeneration layer is relatively small, and the species is simplex which will not be conducive to the development of the forest. The species richness and abundance of the succession layer is beneficial to the forest. The study concluded that the correlation between Changan Forest Park is poor which is in the primary succession stage and needs to be further transformed.
