摘　　要：该研究以三亚市46条主要道路的道路防护绿地树种为对象,调查评价分析了树种整体构成、生长状况、景观效果、生态效益等指标。结果表明:三亚市主要道路防护绿地树种丰富度高,有35科72属123种;选择14个重要评价因子,利用层次分析法,建立滨海城市道路树种综合评价模型,对47种乔木树种进行综合评价,将29种乔木划为Ⅰ级树种,12种乔木划为Ⅱ级,6种乔木划为Ⅲ级;在道路配置模式方面,39.1%的道路为乔木+灌木+草本模式,其次是乔木+灌木模式,有15条道路,21.7%的道路采用乔木+灌木+草本+藤本模式,较少的是乔木单一配置模式和乔木+草本模式。以此研究结果为依据,推荐三亚市道路绿地骨干树种、基调树种、抗风树种、观花树种以及配置模式和指标,为滨海城市绿地树种的优化提供建议。The tree species of 46 main road greenbelts in Sanya City were investigated and analyzed,including the overall composition of tree species,growth status,landscape effects,ecological benefits and other indicators.The results showed that there were 123 species belonging to 72 genera and 35 families in the main road greenbelts in Sanya City,and 14 important evaluation factors were selected.A comprehensive evaluation model of road tree species in coastal cities was established by using analytic hierarchy process.47 tree species were evaluated comprehensively.29 tree species were classified into grade I,12 trees into gradeⅡand 6 trees into gradeⅢ.39.1%of the roads were arbor+shrub+herb mode,followed by arbor+shrub mode,with 15 roads,21.7%of the roads were arbor+shrub+herb+vine mode,the least were single tree planting mode and arbor+herb mode.Based on the results of the study,the backbone tree species,keynote tree species,wind-resistant tree species,flowering tree species and planting patterns and indicators of road green space in Sanya City were recommended,which could provide suggestions for the optimization of tree species in coastal urban green space.
