1如果要在不同的分类群中识别出共同的功能反应群，那么按共同的功能特征对物种进行分类是很重要的。2利用文献资料研究了决定森林植物物种对土地利用变化响应的植物性状。来自8个欧洲国家和4个美国东北部州的数据，包括20项实地研究，提供了216种森林植物的信息。收集了这些物种的13个生活史性状的数据。3欧洲和美国数据集中的性状相关结构相似，与文献中描述的结构一致。欧美草本和欧洲禾本科植物根据其植物性状被聚为不同的挺水类群。欧洲和美国新兴群体的情况相似。4种种子大、繁殖力低、无辅助扩散的挺水植物是相对缓慢的定殖者。分散性（而不是补充）似乎是限制某些森林植物物种定殖的关键因素。禾本科植物的扩散能力和定殖能力之间的关系不太清楚。5基于生活史特征的方法提供了很好的机会来深入了解物种对土地利用变化的反应背后的机制。
1 Classifying species by shared functional characteristics is important if common functional response groups are to be identified among different taxa. 2 We investigated plant traits that determine the response of forest plant species to land use changes using literature data. Sources from eight European countries and four North‐eastern American states, comprising 20 field studies yielded information on 216 forest plant species. For these species, data on 13 life history traits were collected. 3 Trait correlation structure was similar in the European and American data‐sets and corresponded well to those described in the literature. The European and American herbs and the European graminoids were clustered into distinct emergent groups based on their plant traits. The profiles of the European and American emergent groups were similar. 4 Herb species belonging to emergent groups characterized by low dispersability (i.e. large seeds, low fecundity, unassisted dispersal) were relatively slow colonizers. Dispersability (and not recruitment) seems to be a key factor limiting the colonization of some forest plant species. The relationship between dispersability and colonizing capacity was less clear for graminoids. 5 A life history trait‐based approach offers good opportunities to gain insight into the mechanisms behind species response to land‐use change.
