The influence of Gap regeneration dynamics to early-spring herb in the Korean pine broad leaved forests in Changbai Mountain
长白山红松阔叶林林隙动态变化对早春草本植物的影响

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.
