长株潭城市群生态绿心地区地处南方红壤丘陵区的中心地带, 植被区划上属中亚热带常绿阔叶林北部植被亚地带。该区植被以次生林为主, 植被类型复杂多样, 在南方红壤丘陵区现状植被中具有典型代表性, 可为区域植被演替动态和植被恢复研究提供良好的平台。该研究采用统一、规范的方法设置了50个样方, 对区内主要植被类型的物种组成、数量特征、生境信息等进行调查。计算乔木层、灌木层和草本层物种重要值, 运用《中国植被志》编研规范进行植被类型划分和命名, 描述群落物种组成和特征, 并提供10个植被型、22个群系、33个群丛共50个样方的原始数据, 包括森林样方43个, 灌丛样方5个, 草地样方1个, 沼泽样方1个。

The ecological “green-core” area of Changzhutan urban cluster is located in the center of red soil hilly region of Southern China, and the northern vegetation sub-zone of mid-subtropical evergreen broad-leaved forests. In this area, the vegetation is dominated by secondary forests, and the vegetation types are diverse. It is representative of the current vegetation in red soil hilly region of South China, and hance can provide a good platform for the research of regional vegetation succession dynamics and vegetation restoration. We set up 50 plots with a unified and standardized method, and then the species composition, quantitative characteristics, and habitat information of the main vegetation types in the area were investigated. The importance values of species in the tree layer, shrub layer and herb layer were calculated, and the vegetation type of each community were identified and named according to the compilation and research standard of Vegegraphy of China. The community species composition and characteristics were described, and the original data of 50 plots divided into 10 vegetation formations, 22 alliances and 33 associations were provided, including 43 forest plots, 5 shrub plots, 1 grassland plot and 1 swamp plot.
