摘  要：
为研究鄂东地区红椿种群数量动态变化,及其生命周期中生物学特征与种群动态之间的关系,以林木径级代表年龄结构,分析了龄级结构,对种群进行Fourier级数谱分析,并对种群不同龄级动态进行预测。结果表明:黄石红椿种群为增长型;T1和T2种群波谱分析表明,2个种群均有2次明显小周期,种群天然更新存在着周期性,且有小周期的多谐波叠加;动态预测表明红椿种群龄级数量在未来12年、24年和36年间,均为前期先升,中期降,后期稳定,种群趋于老化。

摘  要：
In order to research the dynamics change,and clarify the association between biological characters and population quality in the life cycle of Toona ciliatain in Huangjingshan Mountain,the diameter classes of T. ciliata plants were stood for age classes,numeral dynamics of the plants in different age classes were analyzed,spectral analyses and a prediction for future development of the populations were conducted. The research indicated that the populations were in growth form; in the spectral analyses of the 2 populations,the fundamental waves were each overlaid by 2 different harmonic waves with 2 obvious minor cycles,demonstrating there was a periodicity in natural regeneration of T. ciliata populations; in the prediction for upcoming 12,24,and 36 years,the individual numbers of plants declined first,increased moderately then and stabilized thereafter,the populations was tended to over aging.
