Abstract:

Based on the data collected from sampling plots in Batula luminifera natural forest community located in Shaowu Fujian Province,the important values of main tree species in the comnunity were determined,the community appearance,vertical ctructure,and population dynamics were analysed.The results showed that the community was dominated by Betula luminifera,Catsanopsis lamontii and Liquidambar formosana. The community could be divided into 4 layers.The tree layer could be divided into 3 sulayers in terms of height.The dominance of Betula luminifera in the forest will decrease as the succession proceeds.

Key words: Betula lumminifera natural forest, Community characteristics, Important value
