福建省南靖乐土亚热带雨林探讨

本文分析了南靖和溪的自然条件和群落特征,讨论了南靖县和溪乐土森林群落是否应由原定的“亚热带雨林”改称“亚热带常绿季雨林”的有关问题。结果说明“亚热带雨林”的划分是恰当的,它符合群落学分类原则,比划分为“亚热带常绿季雨林”更符合和溪植被的实际。和溪亚热带雨林,是与我国南亚热带环境相适应的、相对稳定的地带性植被代表之一。

Discussion on Subtropical Rain Forest of Letu, Nanjing County; Fujian Province

The classification of phytocommunities is one of the most disputable questions in the field of phytocoenology. There have always been different classifications of the forest community (in Hexi Letu town, Nanjing County of Fujian Province) as "subtropical rain forest" and "subtropical evergreen seasonal rain forest". Through the analysis of the natural conditions and the characteristics of the phytocommunity in Hexi, and the discussion of the questions put forward by those who favour the classification as "subtropical evergreen seasonal rain forest", this paper aims at justifing the idea that the classification as "subtropical rain forest" is appropriate. It keeps in line with the principle of classification in phytocoenology and, compared with the classification of "subtropical evergreen seasonal rain forest" is more appropriate to the vegetation of Hexi. The subtropical rain forest in Hexi, is one of the typical examples of the zonal vegetation which are fit for the environment of the south subtropic in our country, and are relatively stable.
