| 摘 要： | 将异龄结构的大头茶种群划分为各部份功能群进行研究,得出结论如下:大头茶种群个体数量分布格局主要由苗木群格局决定,种群生物量格局由大树群格局决定;影响大头茶种群格局的因素主要是:①大头茶的强萌生性和弱散布性;②环境因子格局.

| Abstract: | Pattern is the departure from randomness of distribution. The pattern analysis of plant population is to reveal the scales and causal factors of population distribution pattern, in turn, provide the experimental research on the population with the derections.Dividing uneven-aged G. acumenata population into several components, such as large tree group, seedling group, and seed group, is helpful to the analysis of its pattern.The pattern of the populational individuals is determined largely by the pattern of seedling group, and the pattern of the populational biomass, by the pattern of large tree group mainly.There are, in general, two main causal factors of pattern for G. acimenata sprout population, one is its ability to sprout after being cut, the other, environmental factors. |
