本文对我国南岭山地中,西段常绿阔叶林的生态特性、主要植被类型。所包含的热带区系成分及植被的垂直分布等进行了综合研究。对这一植被区中,西段在湖南境内的北部界限作了论述和讨论的同时,分析和比较了南岭东、中、西段的特点和差异。认为南岭各段常绿阔叶林的类型基本相同。因而应是一个自然的植被区,东段和西段的主要区别在于:西段受云贵高原和华中植物区系的影响较大,在植被的种类组成上差异明显;西段中山落叶阔叶树种类和温带植物区系成分比较丰富,常绿落叶阔叶混交林分布范围较广。而越向东移,常绿阔叶林的分布范围愈广,华南区系成分愈多。
In this paper, the ecological characteristics and the main vegetation types of the evergreen broad-leaved forest in the middle and west parts of the Nanling Mountains in China are described. Including the composition of the tropical flora and the vertical distribution of vegetation conducted a comprehensive study. In this vegetation area, the western part of Hunan Province in the northern boundaries were discussed and discussed at the same time, analysis and comparison of Nanling East, Central and Western characteristics and differences. It is considered that the types of evergreen broad-leaved forest in each section of Nanling are basically the same. Therefore, the main difference between the eastern section and the western section lies in that the western section is greatly affected by the Yunnan-Guizhou Plateau and the Central China flora, and has obvious differences in the species composition of the vegetation. The species of deciduous broad-leaved deciduous trees Temperate flora fauna rich, evergreen and deciduous broad-leaved mixed forest wider distribution. The more eastward, the wider the distribution of evergreen broad-leaved forests, the more components of Southern China flora.
