森林幼苗更新对光环境异质性的响应研究进展

Research advance in response of forest seedling regeneration to light environmental heterogeneity.

在分析森林光环境异质性特点的基础上,从幼苗的光合、热耗散、生物量累积和分配、形态特征、萌发和种群动态等方面综述了国内外在森林幼苗更新对光环境异质性响应的研究进展.从森林物种多样性维持、森林演替和植被恢复角度探讨了幼苗更新对光环境异质性不同响应的生态学意义,并对今后该方面研究提出建议.

Based on the analysis of characteristics of forest light environmental heterogeneity,this paper reviewed the research advance in the response of forest seedlings to light environmental heterogeneity from the aspects of photosynthesis,thermal dissipation,biomass accumulation and distribution,morphological traits,germination,and population dynamics,and discussed the ecological significance of different responses of seedling regeneration to light environmental heterogeneity in forest biodiversity maintenance,forest succession,and revegetation.Some suggestions for future research in this field were put forward.
