| 摘 要： | 运用两项局部样方方差(TTLQV)法和成对样方方差(PQV)法对高寒草甸矮嵩草群落中10种植物种群空问分布格局的类型、规模、强度和纹理进行了测定,根据不同区组规模/间隔上两物种间的相关系数r_(i,j),对分布格局的相互关系进行了分析。结果表明:所调查种群的分布格局都呈集聚分布;密度格局强度与环境格局强度在种间的变化基本一致;格局的强度与纹理之间并无直接关系;种群分布格局间的关系表明了种间发生相互作用的基本生境尺度。

| Abstract: | The types, scales, intensities and grains of pattern were measured by the methods of TTLQV and PQV in 10 species. The relationship between patterns of species were analysed based on corelation coefficient in different block size/interval. The results showed that the patterns of 10 species were clump distribution. The change of intensities of pattern that caused by population indensity and by environment factor was similarity among species. No direct relationship between intensities and grains of pattern. The relationship between patterns indicated the basal habitat scale of interspecific coreaction. |
