摘要
为更好地推进生态园林城市建设,提升太原城市道路绿化水平,对太原市区道路行道树组成结构、生长状况开展研究。结果表明,1)太原市常用行道树共15种,隶属于9科12属,其中,槐树(Sophora japonica)的应用远超其余14种。2)行道树径级和冠幅均偏小,径级和垂直空间分布不均。3)行道树整体种植施工质量和健康情况良好,但"小脑袋"行道树较多。当前太原市行道树应用的关键是加强新品种引进及幼树培养,并严格绿化施工。
In order to promote the construction of ecology garden city, to enhance the street greening level in Taiyuan, capital of Shanxi Province, the differences in species composition, application frequency, structure of DBH （diameter at breast height） ,composition of the tree height and health status of street trees in cen- tral districts of Taiyuan were investigated. The results showed that 1） there were 15 species of street trees belonging to 12 genera in 8 families in urban road green space in Taiyuan, and Sophora japonica was the most widely used one. 2） The average DBH and crown of street trees throughout the city were relatively small,the distribution of DBH and vertical space structure were not evenly distributed. 3） The street trees were generally healthy and well planted,while the crowns of quite a few trees were heavily cut. According to the application problems of street trees, it was suggested that of introduce new varieties, to pay attention to the cultivation of young street trees,to strictly enforce the greening construction.
