厦门市主要道路绿化树种组成及问题分析

Analysis on the Composition and Problem of the Greening Tree Species on the Main Road in Xiamen

为了解厦门市岛内现行道路绿化树种组成结构和存在问题,研究通过连续多年对厦门市岛内17条城市道路的绿化树种的组成进行调查,并系统分析了各树种在绿带分布、潜在破坏力、开花特性以及抗风性方面的主要特征和潜在问题。结果显示,厦门市道路绿化树种组成较为丰富,但是中分绿带和行道树绿带中出现了明显不适合在此区域种植的树种;同时,具有潜在破坏力的树种比例明显偏高,而树种观赏性方面略显单一,具有观花特性的树种比例不足;并且大部分绿化树种具有一定的抗风性,但在应对强台风能力上有较多树种显现出明显缺陷。

In order to understand the composition structure and existing problems of the existing road greening tree species in Xiamen Island, the composition of greening tree species of 17 urban roads in Xiamen were investigated for many years, and the main characteristics and potential problems of tree species in green belt distribution, potential destructive power, flowering characteristics and wind resistance were systematically analyzed. The results show that the composition of road greening tree species in Xiamen is relatively rich, but there are obvious tree species which are not suitable for planting in this area. Meanwhile, the proportion of tree species with potential destructive power is obviously high, while the ornamental tree species are slightly single, and the proportion of tree species with flower viewing characteristics is insufficient. Most of the greening trees have certain resistance to the wind. However, there are many tree species with obvious defects in the ability to cope with strong typhoon.
