从种子生产到幼苗定居的更新是植物生活史中最为敏感的阶段之一，多种因素的影响种子和幼苗的命运。

The stage from seed production to seedling colonization is the most sensitive stage in plant life history . After seed dispersal , numerous biotic and abiotic factors influence seed fates and seedling mortality .

资源分配的模式可以反映植物生活史特征，是植物生活史研究的核心，近年来，对资源分配的研究主要集中在性分配和繁殖分配两方面。

The mode of resources allocation can reflect the character of the plant life history , which is central to study of plant life history . Studies on resource allocation were focused on two aspects : sex allocation and reproductive allocation .

生活史策略随占支配地位的环境因子的变动而作出调整，即生活史特性响应不同环境的生态属性，引起植物的生活史策略在Grime模型C-R-S轴上的迁移。

With the variety of the ascendancy environment factors , life-history strategies according to change , that is , characteristics of life history respond to ecological attribute , so plant functionality have move in C-R-S axis of Grime model .
