广州市公园园林灌木资源及其景观特色调查与分析

Investigation and Analysis of the Resources of Landscape Shrubs and Their Landscape Characteristics in Guangzhou Parks

植物区系地理成分,可表征园林植物的应用是否符合该地区的生态气候特征。通过对广州市12个城市公园灌木的调查,分析其科属的地理成分及配置特色,以期对广州地区园林灌木的应用及景观设计提供理论依据。结果显示,广州公园灌木共201种(含变种),隶属47科109属,其中地带性植物40科84属121种,占总种数的60.2%;公园灌木地理成分以热带性科、属为主,分别为27科、76属,占总科、属数的57.45%和69.72%,符合当地的生态环境特点;广州公园灌木植物景观具有热带特色和地带性特色。

The floristic geographical elements of plants can represent whether the landscape plants adapt to the eco-climatic characteristics of the region. Through the investigation of landscape shrubs in Guangzbou parks, their floristic elements of families and genera, and plant design characteristics are analyzed, to provide theoretical basis for the application and plant design of landscape shrubs in Guangzhou. The results showed that there are 201 species （including varieties）, belonging to 47 families and 109 genera in Guangzhou parks. Of these, 121 species were indigenous plants, accounting for 60.2% of the total, belonging to 40 families and 84 genera. The floristic geographical elements showed that there are 27 tropical families, 76 tropical genera, at 57.45% of the tropical families and 69.72% of the tropical genera. These results demonstrate that the landscape shrubs have clear tropical characteristics in Guangzhou parks, and in accordance with the eco- climatic characteristics of Guangzhou, Landscape shrubs in Guangzhou parks have tropical characteristics and indigenous characteristics.
