摘　　要：Based on a vast of field investigation on stamps in Tilia broad-leaved Korean pine forest on northem 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 quantity 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.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.
