摘　　要：对福州市人行道上栽种的17种行道树进行实地调查,结果表明:除了假槟榔外,其余16种树种根系都产生不同程度的破坏;高山榕、大叶榕、木棉、小叶榕、南洋楹等5种树种根系的破坏性最大;胸径与硬体的破坏率呈正相关;福州市行道树的生长空间普遍不足,种植穴尺寸缺乏规范是造成行道树根系破坏路面的一个重要原因.Seventeen species( totally 1615 street trees) were investigated in Fuzhou. The results showed that 16 species damaged hardscape seriously,except for Archontophoenix alexandrae. The levels of root damage of most investigated trees were in positive correlation with diameter at breast height( DBH). There were significant differences in the proportions of trees of different species,which caused hardscape damage.
