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 s...
