摘  要:
生境异质性普遍存在于自然环境中,作为植物生长最重要的生境因子之一,土壤养分资源水平的异质分布在植物个体及种群大小、觅养生长格局、能量投资和繁殖分配等多种维度影响克隆植物表型可塑性,蕴含着重要的生态适应意义。通过综述克隆植物个体及种群特征在不同土壤养分资源水平下的表现型差异和分化,分析了表现型差异和分化的内存机理,探讨了克隆植物对土壤养分资源水平的生态应答对策和生态适应策略。

摘  要:
Habitat heterogeneity exists in the natural environment.As one of the most important habitat factors for plant growth,the heterogeneous distribution of soil nutrient level affected the phenotypic plasticity of clonal plants from the plant individual and population size,foraging growth pattern,energy investment and reproductive allocation,which indicated an important significance of ecological adaptation.By summarizing the differences and differentiations of individual and population characteristics at different levels of soil nutrient resources,the mechanisms of the differences and differentiation were analyzed.The ecological response countermeasures and ecological adaptation strategies of clonal plants at different levels of soil nutrient resources were discussed.
