摘要
植物功能群是研究复杂生态系统结构和功能的有效途径,有别于spec ies-spec ies方法。该方法被提出后受到广泛重视,并用于生态系统研究的各个领域。介绍了植物功能群的概念、划分标准,总结了目前功能群在实践研究中的应用,包括在生物多样性研究、干扰因素存在下草地生态系统变化研究以及全球气候变化模型建立方面的应用,分析了在植物功能群定义和划分标准中存在的分歧,认为对功能群定义及划分标准的完善是今后功能群研究的关键。
As an effective approach to researching the complex structure and functions of the ecosystem, plant functional group is different from the species - species method. It has received much attention and has been widely used in ecosystem research since it was proposed. This paper presents the definition and classification criteria of plant functional groups. It also summarizes their applications in real -world research, including research on biodiversity, research on changes in the grassland ecosystem with disturbing factors and the establishment of the global climate change model. It analyzes disagreement about the definition and classification criteria of plant functional groups. It is believed that the key to future research on functional groups is to perfect their definition and classification criteria.
