北京市园林植物数量生态关系的研究--以陶然亭月季园为例

以北京市陶然亭公园内的月季园为例，应用DCA、TWINSPAN、综合多样性指数等数量分析方法，对北京市园林绿化植物进行生态关系的研究。结果表明：月季园内植物群落划分为6个群落类型，分类和排序的结果都反映出土壤水分和温度两个环境梯度。且随着土壤水分的增加，物种多样性增加。乔木群落多样性高于灌丛群落多样性，其中刺槐与刺柏具有最高的综合多样性指数值。

Ecological Relationship of Garden Plants in Beijing--A Case of Rose Garden in Taoranting

Using the rose garden in the Taoranting Park located in Beijing as its subject,the case study adopted such methods as DCA,TWINSPAN and Comprehensive index system to quantitatively study the ecological relationship of garden plants.The results showed that in the Rose garden,the plants were divided into six types of communities whose classification and ordination both reflected the gradients of soil moisture and temperature.Meantime,the species became more diversified with increased soil moisture.The diversity of arbor communities was higher than that of shrub communities,and Robinia pseudoacacia and Juniperus formosana presented the highest diversity indexes among all the plants in the garden.
