| 为掌握太原市街道绿化植物资源现状，采用分层随机抽样法，选取269条样带进行调查，并分析了太原市街道绿化植物种类组成、应用频度和不同等级道路植物应用情况。结果表明，太原市街道绿化植物资源共64种，隶属28科、42属，其中乔木植物38种，灌草植物26种。街道绿化树种结构欠合理，乔木与灌草数量比例为1.46∶1，常绿与落叶植物数量比例为0.3∶1；乔木植物中国槐应用频度达到84.39%，灌草植物中黄杨和大叶黄杨的应用频度分别达到32.71%和27.88%。主干道、次干道与支路植物应用数量依次递减。基于太原市街道绿化植物资源应用现状，提出政府主导，科学规划，充分挖掘潜力物种，引进优良树种，发展立体绿化，提高现有街道绿化管护水平，强化精细化管理等改进建议，旨在缓解目前存在的问题，并为城市街道绿化建设和管理提供理论基础。 |

| In order to master the current situation of the street greening plant resources in Taiyuan, 269 transects were selected for investigation by stratified random sampling method, and the species composition, application frequency and number of plant species of different grade roads were analyzed. The results showed that there were 64 species of street greening plants in Taiyuan, belonging to 42 genera and 28 families, including 38 species of arbors and 26 species of shrubs and herbs. The structure of street greening tree species was not reasonable. The proportion of arbors to shrubs and herbs was 1.46∶1, and the proportion of evergreen to deciduous plants was 0.3∶1; the application frequency of Sophora japonica in arbors reached 84.39%, and the application frequency of Buxus sinica and Euonymus japonicus in shrubs and herbs reached 32.71% and 27.88%, respectively. The application number of plant species of arterial road, sub-arterial road and branch road were in descending order. Based on the application status of street greening plants in Taiyuan, this paper put forward some suggestions for improvement, such as government led, scientific planning, fully developing potential species, introducing fine tree species, developing three-dimensional greening, improving the management and protection level of existing street greening, and strengthening fine management, in order to alleviate the existing problems and provide a theoretical basis for the construction and management of urban street greening. |
