| 摘 要： | 本文根据6年定位研究结果,讨论了东北山溪激流中整株越冬的草本植物─-水毛茛的有关种群生态方面的问题;诸如水毛茛种群的空间分布格局、种群年龄区段结构和种群数量的周期性变动等;并利用观测数据编制了水毛茛种群的静态生命表,绘制了种群的存活曲线和死亡动态曲线,根据种群生殖力表计算了种群的内禀增长能力.利用逻辑斯蒂标准曲线对植物种群数量增长曲线进行拟合.最后对年龄区段的划分及其在生命表中的作用、种群数量变动及其影响因素、迁入与迁出对水毛茛种群大小的影响等进行了探讨.

| Abstract: | The population ecology of Ranunculus bungei Steud.was investigated in a rapidflowingstream in North Temperate from 1986 to 1991. The distribution pattern and the age structureof the plant population, and the periodic change of the population size are reported,and soare the static life table and the fecundity schedules.The survival curve and the Overwinteringcurve as well as the innate capacity for increase are presented.The logistic curves are simu-lated for the curves of the population size and the number of individuals by reproduction ofthe population, Changes of the population size are discussed in relation with emigration andimmigration proeesses. |
