湖南洞庭湖区为常绿阔叶林区,有植物种类159科492属873种,组成62个植物群落(lommunity)。其中东亚和北美分布型及东亚分布型两种成分在丘陵岗地上的地带性植被中作用显著,温带分布型与中国特有成分对其有明显影响。湖泊、洲滩的植被是隐域性的,主要由世界广布成分所构成。丘陵岗地、湖泊、洲滩三个类型系统,在植物群落类型与空间组合、植物区系与地理成分、生活型与层片等特征上,都存在着明显的分异。植被有在大区域内呈插花式镶嵌分布,在小区域或特定环境内按同心圆分布,在水生、湿生和中生三个生态系列上呈成带分布的特点。
The Dongting Lake area in Hunan Province is an evergreen broad-leaved forest area. There are 873 plant species belonging to 492 genera and 159 families, making up 62 plant communities (lommunity). Among them, the distributions of East Asia and North America and the distribution of East Asia play a significant role in the zonal vegetation on hilly land, and temperate distribution and Chinese endemic composition have significant effects on them. Lakes, Chau Beach vegetation is a hidden nature, mainly composed of a broad component of the world. Hilly land, lakes and beaches of the three types of systems, there are obvious differences in the characteristics of plant community types and spatial assemblages, flora and geography, life forms and plies. Vegetation in the large area was inlaid mosaic distribution, in a small area or within a specific environment concentric distribution, in the aquatic, wet and in the three ecological series with the characteristics of the distribution.
