摘  要:
在群落调查与树干解析的基础上,对齐云山自然保护区长苞铁杉与福建柏两种珍稀植物的生长过程及种群发展动态进行研究。结果表明:(1)除福建柏的胸径生长最符合一元幂函数方程外,其树高、材积和长苞铁杉的胸径、树高、材积生长过程都可用R ichards方程进行最佳拟合;(2)两珍稀植物种群的年龄结构均呈"金字塔"型;(3)两种植物的存活曲线趋于Deevey-C型,且福建柏的曲线斜率大于长苞铁杉,说明前者早期死亡率较后者高。这些结果为保护区珍稀植物的种群生长、种质资源保护、开发利用提供了理论参考。

摘  要:
Baesed on community investigation,trunk analysis,the growth law of DBH,height(H) and volume(V) and the population characteristics of Tsuga longibracteata and Fokienia hoginsii in Qiyunshan Natural Reserve,Jiangxi Province were studied.The results showed as follows:(1)Except for the DBH of F.hoginsii,which accorded with Power Function,the others were matched to Richards Function.(2)The age structures of the two rare species showed a "Pyrimid"type,indicating that they are developing population.(3)The survival curves of the two species belonged to Deevey-C type,and the rate of curve of F.hoginsii was more steep than that of T.longibracteata,impicating that the mortality of the former is larger than that of the later in the young stage.These results were helpful to the protection,regeneration and utilization of these two species and their stands.
