摘要
随着全球气候变化加剧,各地极端气候现象频发,如何有效应对极端气候对城市绿化的影响是当前城市建设需要深入思考的问题。以2018年1月末南昌持续4天的极端冰冻灾害天气为契机,通过对典型样地的遴选和样地调查,对行道树及其生境的相互适应关系,以及其对冰冻灾害的响应机制做出分析,结果表明:1)行道树与道路宽度、株行距、路侧建筑等空间环境有密切关系,树木的生长受到道路空间形态的限制,并反映出相应的形态适应性;2)由于竞争促进作用,香樟长势背阴环境优于阳面环境;3)背阴环境中的香樟遭受冰雪灾害的损害程度较阳面严重,树冠的优势方向折枝较严重。
With the aggravation of global climate, frequent occurrence of extreme climate on urban greening is an issue that needs to be deeply considered in current urban construction. Taking the four days extreme freeze disaster weather in Nanchang in January 2018 as an opportunity, through the typical sample area selection, and sample plot survey, the mutual adaptation relationship between roadside trees and their habitats as well as their response mechanism to freezing disaster were analyzed. The results show that: 1) There is a close relationship between roadside trees and space environment, such as road width, plant spacing and roadside buildings. 2) Due to the promotion of competition, the growth of Cinnamomum camphora in the shady environment was better than that of Cinnamomum camphora on the sunny side environment. 3) The degree of damage of Cinnamomum camphora suffered from the sunny side environment, and the dominant direction of canopy branches was more serious.
