A Study on the Regularity of Natural Exbucklandia tonkinensis Population Dynamics in Jinggang Mountain

Liu Renlin,Zeng Bin,Song Dunfu,Zeng Dongdong (Ganzhou Forestry School of Jiangxi 341002)  
The reasults from this paper's analysis of natural Exbuchlandia tonkiensis community of Jinggang Mountain studied by Fourier translation shows that there is a marked regularity of periodic fluctuations in the process of natural regeneration of Bigfruit Exbucklandia as followings:the long periodic fluctuation is 140 years;the middle one is 70 years;the short one is 28~35 years. It was discovered that the periodic fluctuation of the annual growth of a Bigfruit Exbucklandia tree was coincident with that of the natural regeneration process.However,it also be indicated that the generation of Bigfruit Exbucklandia is 70 years in natural community, and 25 years in cultured community with the analysis above. This paper will be effective for sustainable use and management of natural forests.
