基于生物量分配格局的植物生长策略研究进展

由于植物的生物量是其获取外界资源的基础,生物量分配是植物对资源利用最大化的一种生长策略,探讨了不同环境下的生长策略有助于预测未来环境变化下植物的生长和分布趋势。分别从自然环境和人为干扰两种因素下综述了植物在不同生态条件下生物量的分配格局,总结了在不同生长条件下植物各构件生物量分配差异,阐述了植物通过改变地上与地下部分,生殖与营养器官,枝叶等生物量分配格局应对环境挑战。植物对环境表现出的不同生长适应能力,不仅依赖于自身固有的生存策略特性,还依赖于不同环境下生物量分配格局的响应强度,据此提出了今后应进一步挖掘植物适应环境的时间动态、响应尺度大小和生理过程等内在机制的研究建议。

Research Progress of Plant Growth Strategies Based on Biomass Allocation Patterns

Plant biomass is the basis for obtaining external resources.Biomass allocation is a growth strategy for maximizing the utilization of resources.Exploring the growth strategies in different environment is helpful to predict the growth and distribution trend of plants under future environmental changes.This paper summarizes the biomass distribution patterns of plants under different ecological conditions from two factors of natural environment and human disturbance,summarizes the biomass distribution differences of plant components under different growth conditions,and expounds plants that respond to environmental challenges by changing the biomass distribution patterns of aboveground and underground parts,reproductive and vegetative organs,branches and leaves.The different growth adaptability of plants to the environment depends not only on their own inherent survival strategy characteristics,but also on the response intensity of biomass allocation patterns in different environment.It is suggested to further explore the internal mechanisms of plant adaptation to the environment,such as time dynamics,response scale and physiological process in the future.
