| 摘 要： | 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.

| Abstract: | 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. |
