摘要
采用随机样方法,调查了广州市3类城市绿地中的1 483株园林树木的健康状况,结果显示大部分的园林树木生长较健康,园林树木生长存在的主要问题是枝叶病、虫害等。3类绿地5类亚型中,园林树木健康高低次序是:公园人工植被>路侧绿带>行道树绿带>公园自然植被>校园绿地。园林树木健康与植物多样性指标的相关分析结果显示,城市绿地中的园林树木的生长状况与植物多样性有一定的联系。根据调查的结果,对城市绿地的园林树木管养和配置提出了建议。
In this paper,we put forward some suggestions on the breeding,the management and the design of ornamental plants after making an investigation and assessment of the health of the landscape trees in the green land in Guangzhou.Through the investigation of 1 483 landscape trees,we found that most of them were healthy and that branch-leaf diseases and insect pest were the main factors causing bad impact on the growth of the trees.Among the five investigated plants in three different types of green lands(park,school and road-side),artificial vegetation in parks topped on the health list followed by road-side green belt,street trees,natural vegetation in parks and green plants in schools.It is concluded that the growth of landscape trees has something to do with the versatility of plants in Guangzhou.
