The poit-centered quarter method and its method of analysis have been used to study the population pattern of dominant species in Quercus langispica sprouted shrub community which is located in Dashao, an area in northwest part of Kunming. The patterns in different sides of the slope also been compared. The results express that the main population pattern of Quercus langispica and Myrsine africana in Quercus langispica sprouted shrub community at Dashao are clump distribution.

The poit-centered quarter method and its method of analysis have been used to study the population pattern of dominant species in Quercus langispica sprouted shrub community which is located in Dashao, an area in northwest part of Kunming. The patterns in different sides of the slope also been compared. The results express that the main population pattern of Quercus langispica and Myrsine africana in Quercus langispica sprouted shrub community at Dashao are clump distribution. The main reason is that the soil is inlaid with calcareous rocks. In the meantime, the harvest method has been used to measure the biomass now existed in Quercus langispica sprouted shrub community. There are total 27.46 t/ hm2 biomass, above the ground is 6.52 t/ hm2 and under the ground is 20.94 t / hm2.

采用点—四分抽样技术及其分析方法,对昆明大哨附近广泛分布的长穗高山栎灌丛中优势种群的分布格局进行了研究,并对不同坡向的种群分布格局进行了比较.结果显示主要种群是以聚群分布为主要格局.还探讨了分布格局的成因.同时利用收割法对群落的生物量进行了研究,群落总生物量为27.46t/hm~2,地下部分生物量是地上部分生物量的 3.2倍强.

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 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.

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。

The outputs showthat the three mangrove species are clump distribution.

本文以Simpson指数、Shannon一Wiener指数、种间相遇率(PIE)和均匀度公式研究了深圳福田红树林群落的物种多样性,结果为:Simpen指数为1.40,Shannon一Wiener指教为0.78,PIE为0.28,均匀度为18.98%。生态优势度为0.56.与南亚热带常绿阔叶林群落相比,红树林群落的多样性指数和均匀度明显偏低,生态优势度则偏高。利用方差/均值法测定了种群分布格局,结果表明,3个种均趋于集群分布。
