Abstract

Abstract: Digital camera was used to take pictures of street trees, and Photoshop software was used to calculate the green belt porosity. Based on the data, the relationships of green belt porosity and traffic noise reduction were analyzed. The results showed that the green belt porosity of Yangqiao Middle Road, Wusi Road, Bayiqi Road, Shangxiadian Road, Industry Road and North Riverside Road were 0.683, 0.752, 0.600, 0.767, 0.909 and 0.787 respectively. The porosity sequences of street trees were as follows: Cinnamomum camphora (childhood), Bombax ceiba, Bauhinia purpurea, Mangifera indica, Ficus microcarpa and Cinnamomum camphora (adult). The relationships between the street tree porosity of layer A and the traffic noise reduction were obviously negative. This study provides an important theoretical foundation and practical reference for the configuration of street trees.

摘要： 运用Photoshop软件对数码相机拍摄的行道树绿化带相片进行处理并测定其疏透度，然后分析其与降低交通噪音效果的相关关系。结果表明：福州市杨桥中路、五四路、八一七路、上下店路、工业路、北江滨大道的行道树绿化带疏透度值分别为0.683，0.752，0.600，0.767，0.909，0.787；不同行道树疏透度由大到小依次为：樟树（幼年）、木棉、羊蹄甲、芒果、榕树和樟树（成年）；相关分析结果表明各行道树A层的疏透度与降低噪音效果具有显著的负相关关系。研究为行道树的合理配置提供重要的理论依据和实际参考价值。
