摘要
城市行道树的飞毛飞絮是城市常见植源性污染,常引起部分人群的不适症状.以南京常见行道树为研究对象,选取二球悬铃木和意杨2种主要致敏行道树进行深入研究,分析了2种致敏树种的生物学特性以及飞毛飞絮的飘散特点,提出通过无果品系选育、树冠嫁接等的控花控果法,丰富植物群落结构法及合理利用风力作用法等措施来控制致敏树种的飞毛飞絮危害办法.
The catkins of street trees are the common plant-caused pollutions in cities, which can cause some peoper feel unwell. This paper takes the Nanjing street trees as the study case,choosing two major allergenic trees （Platanus acerifolia and Italian poplar） to investigate deeply, analyzing the biological characteristics of the two allergenic trees and the shape characteristics of the catkins. And thus, some ways are put forward to control the harm by catkins, such as the method of no-fruit breeding, crown grafting, the method of enriching plant community structure, and the method by rational utilization of the wind.
