Abstract

Abstract:

Based on a lot of field investigation of stumps in Tilia broadleaf Korean pine forest,the results showed that Korean pine forest was composed of grouped patched trees with different ages.The dominated generations had not showed strict difference.The community age structure always appeared two or more peaks.The distribution of broadleaf tree species in Korean pine forest was grouped or scattered.Age distribution of broadleaf trees was uneven-aged.There existed apparent species number increase and decrease relation between broadleaf species and Korean pine.So,it shaped multi-storied and mixed forest.The model of age structure and growth showed their positive correlation trend,but growth began to lessen when woods had grown into old age.

Key words: Tilia broadleaf Korean pine forest, Age structure
