摘    要:作为淡水水体的主要初级生产者,浮游植物群落对环境变化的响应十分迅速,因此被用来作为评估水体生态系统状况的指示性生物类群.如何利用浮游植物群落的种类组成信息,来解读其所响应的生态环境特征和变化,以及认识浮游群落结构变化的过程和驱动因素一直是淡水生态学研究的重要内容.根据生态位原理,生态学家们把生活习性和生存策略相似的浮游植物种类归于同一个"功能群",作为群落结构与响应分析的基本单元.浮游植物功能群已被广泛应用于各种淡水水体,功能群的分类和方法也得到了不断的改进和完善.应用较多的功能群划分系统有FG、MFG、MBFG和PFT.目前,我国浮游植物工作者也陆续开始采用浮游植物功能群来分析群落结构和反映水体环境特征,但常常会面临功能群划分上的困难.由于不同功能群划分方法存在较大差异,在使用上需要了解不同划分方法的原理和差别.本文综述了这4种功能群分类方法的特征和应用情况,并对它们的优劣进行了评价和对比,同时介绍了基于功能群的Q指数评价方法,为我国浮游植物群落水平上的相关研究和应用提供方便与参考.

关 键 词:浮游植物  功能群  分类

Abstract:As the primary producers in lakes and reservoirs, phytoplankton assemblages act promptly to environmental changes. They are the most important biological indicators for evaluating the status of aquatic ecosystems. It is a challenging task in freshwater ecology to reveal the driving mechanism of phytoplankton succession and their structural responses to environmental changes through the information within their assemblages. Ecologists ascribe phytoplankton species sharing identical or similar life style and living strategy into a basic unit-"functional group" in the response analysis to environmental change. As functional groups could accurately reflect the changes of aquatic environments, the functional grouping methods have been widely applied in many aspects of freshwater phytoplankton ecology. The classification of functional groups has also been improved and supplemented in the recent applications. The most popular functional classification systems are the FG (Functional Groups), MFG (Morpho-Functional Groups), MBFG (Morphology-Based Functional Groups) and PFT (Plant Functional Types). These classification methods have been used recently to analyse the relationship between phytoplankton assemblages and their aquatic environmental variables in China. As there existing fundamental difference between these classification methods, the users usually face difficulties in ascribing clearly every phytoplankton species into the right functional groups. The paper reviewed the features of each classification method and its application to improve the application in China.
Keywords:Phytoplankton  functional group  taxonomy
