摘要: 采用抽样调查方法, 设置了138个样点, 调查了2 789株样木的胸径(地径)、树高、冠幅直径等指标, 对北京市城区现有园林植物的个体大小(胸径、树高、冠幅)、平均状况、按直径株数分布、按树高株数分布、径高关系模型、直径冠幅模型等进行了研究, 探讨了园林植物与自然条件下植物截然不同的统计特性。

Abstract: By using sampling method, 2 789 sample trees in 138 sample plo ts were measured in Dongcheng District of Beijing Municipality. The measurements include their individual diameter, height and crow n sizes.Based on the mensurements, research work was conducted on their distribution in terms of diameter and height, modelling of diameter-height relationship and modelling of diameter-crow n size relationship.Statistic features between garden plants and plants under the natural conditions were also studied.

Key words: urban garden plants, average diameter and height, distribution
