| Abstract: | Based on a vast of field investigation on stamps inTilia broad-leaved Korean pine forest on northern slope of Changbai Mountain, age structure of some major species were studied
in this paper. The results showed that Korean pine population was composed of grouped patches with different ages. There were
not strict intervals among the dominated generations, and the curve of age structure often had two or more peaks. The distribution
of broad-leaved species in natural Korean pine forest was grouped or scattered, and age distribution was also uneven-aged.
There existed close relation between quality of broad-leaved species and Korean pine. So, it shaped multi-storied and uneven-aged
mixed forest. The model of age structure and growth demonstrated their passive correlation, but growth became slow when woods
had reached old age.
The study was funded by the Opened Research Station of Changbai Mountain Forest Ecosystems, the Chinese Academy of Sciences.
