应对台风侵袭的上海市行道树的空间结构特征研究
Spatial structure characteristics of street trees in Shanghai in response to typhoon invasion
摘要
Abstract
Typhoons land in China's coastal cities,causing varying degrees of damage to urban street trees.The selection and optimal allocation of wind-resistant landscape trees are of great importance in maintaining the ecological security of urban greening ecosystem.Based on Baidu Street View map technology,supplemented by field survey,the street species,road section distribution and spatial pattern in Shanghai was studied in this paper.Taking Metasequoia glyptostroboides,Firmiana simplex,Camphora officinarum,Koelreuteria bipinnata and Platanus acerifolia as benchmark tree species,the wind resistance of 27 common street trees was sequenced,the spatial structure characteristics of street trees were analyzed with ArcGIS.Results were as follows:(1)Among segments with street trees in Shanghai,evergreen tree species accounted for 64.37％,demonstrating a multi-centric scattered clustering pattern.Deciduous tree species accounted for 35.63％,showing high central urban clustering.(2)Key tree species showed distinct spatial patterns:Platanus acerifolia was highly concentrated in the central urban area.Metasequoia glyptostroboides formed dense zonal distributions in Chongming and coastal regions.Ginkgo biloba and Koelreuteria bipinnata were concentrated in built-up areas of the central city and secondary urban centers.Camphora officinarum,as a keynote species,was uniformly distributed across the city.Based on these findings,two critical issues were identified:limited diversity in wind-resistant tree species and insufficient spatial alignment between wind-resistant species and Shanghai's wind environment.Three optimization strategies for street tree configurations were proposed:(1)Increase the proportion of wind-resistant species and diversify the street tree composition.(2)Develop comprehensive wind-resistance evaluation criteria to enhance species selection and breeding.(3)Implement context-specific street tree configurations to optimize the spatial pattern of wind resistance in urban areas.This study not only explores novel methods for tree species survey and statistics but also provides a countermeasure for enhancing wind resistance in urban greening.关键词
