摘要

应用离散富里叶变换研究井冈山天然大果马蹄荷( Exbucklandia tonkinensis Steenis) 的种群动态规律, 结果表:大果马蹄荷种群动态存在着周期波动规律, 大周期为 140 , 中周期 70 , 小周期 28 35 , 与大果马蹄荷个体生长的周期波动一致天然大果马蹄荷的世代划分以 70 年为宜, 人工林以 25 年为宜该研究结果可为天然林的管理和持续利用提供科学依据
 

Abstract

The population analysis of natural Exbucklandia tonkinensis Steenis of Jingg ang Mountain
by Fourier Translation show ed that there is a marked regularity of periodic fluctuatio ns in the process of natural regeneration as follow s
:the long periodic fluctuation is 140 years, the middle one is 70 years and the sho rt one is 28 35 years .It is discovered that the periodic fluctuation of the annual growth of individual tree is coincident w ith the natural regeneration process .How ever, it also indicated that the generation of E xbucklandia tonkinensis Steenis is 70 years in natural comm unity and 25 y ears in cultured community acco rding to the analyses above .It w ill be effective for sustainable utilization and management of natural forests from the result .
