摘要
采用生态学的方法,系统分析了长白山红松阔叶林林冠空隙的动态变化对早春草本层植物的分布密度和生物量的影响以及早春草本层植物对林冠空隙的反应,进而探讨了早春草本层植物在红松阔叶林森林生态系统中所起的生态作用。
The influence of Gap regeneration dynamics to density and biomass of herb in early spring in the Korean pine broad leaved forests in Changbai Mountain was systematically analyzed.It is an essential prerequisite in studying material and energy flows in forest ecosystem.The regeneration response and the ecological action of herb to gaps were studied.The density and biomass in the gaps are 50% and 100% more in comparison with there under conapy.There are ten more species in the gaps.This research provides a scientific basis for studying the structure and function of forest ecosysatem,and cycling of forest.
