Abstract

Background

Vegetation science research has been conducted for approximately 200 years; however, until now there has not been a unified classification principle or system that was acceptable to vegetation scientists. To facilitate the development of vegetation science and its applications in natural conservation, a unified vegetation classification system is urgently required. Here we propose a unified eco-physiognomic-floristic vegetation classification system (EcoFloVCS) that combines eco-physiognomic and floristic characteristic classification systems.

Methods

Under the EcoFloVCS, plant communities are considered to have six key components (species composition, structure, habitat, development, locality, and function). Six associated characteristics are derived from these six components (dominant species, diagnostic species, physiognomy, distribution patterns, dynamics, and disturbance processes). These characteristics are used as the basis for community classification.

Results and Conclusions

The high-level units of this system agree with the UNESCO system, whereas the middle- and low-level units correspond to the Braun-Blanquet classification system. Both are connected by a Division (Subformation) unit. Based on the EcoFloVCS, a vegetation system was constructed for the four highest units worldwide that included seven Formation Classes, 22 Formation Subclasses, 39 Formation Groups, and 119 Formations. We assume that vegetation science will benefit from our unified EcoFloVCS through comparing and understanding community structures and functions on a global scale.

EcoFloVCS：一种生态地貌-区系植被分类系统

植被科学研究已有近200年的历史；然而，到目前为止，还没有一个为植被科学家所接受的统一的分类原则或系统。为了促进植被科学的发展及其在自然保护中的应用，迫切需要一个统一的植被分类体系。本文提出了一种结合生态地貌和植物区系特征的统一生态地貌植被分类系统（EcoFloVCS）。方法在EcoFloVCS下，植物群落由物种组成、结构、生境、发育、局地和功能6个要素组成。六个相关特征来源于这六个组成部分（优势种、诊断种、地貌、分布模式、动态和干扰过程）。这些特征作为群落分类的依据。结果与结论该分类系统的高层单位与联合国教科文组织分类系统一致，而中低层单位与布朗-布兰凯分类系统一致。两者由一个Division （Subformation）单元连接。基于EcoFloVCS，构建了全球4个最高单元的植被系统，包括7个地层类、22个地层亚类、39个地层群和119个地层。我们认为，通过比较和理解全球范围内的群落结构和功能，我们统一的EcoFloVCS将使植被科学受益。

期刊介绍： Applied Vegetation Science focuses on community-level topics relevant to human interaction with vegetation, including global change, nature conservation, nature management, restoration of plant communities and of natural habitats, and the planning of semi-natural and urban landscapes. Vegetation survey, modelling and remote-sensing applications are welcome. Papers on vegetation science which do not fit to this scope (do not have an applied aspect and are not vegetation survey) should be directed to our associate journal, the Journal of Vegetation Science. Both journals publish papers on the ecology of a single species only if it plays a key role in structuring plant communities.
