| 摘 要： | 对拂子茅、假苇拂子茅、硬拂子茅３种拂子茅种群圆锥花序小穗的分布格局分析，结果表明，３种拂子茅种群在各节位上的小穗数均适合于Ｗｅｉｂｕｌｌ分布，随着节位序的增加均呈饱和型指数增长，通过赋予各统计参数生物生态学涵义，从宏观上分析与揭示了有关生命现象与发展规律及其生物生态学机理。

| Abstract: | An investigation on the distribution pattern of spikelets in conical inflorescence of Calamagrostis epigeios, C. pseudophragmites and C. ripidula populations showed that the distribution of spikelets in all the three cases was consistent with Weibull distribution, and the number of spikelets increased exponentially with the order of spike nodes. Given biological and ecological interpretation to the statistical parameters used in the analysis, the regularity and mechanism in development of the species could be seen more clearly at a macro level of life phenomena. |
