以长春高新技术产业开发区道路绿地为调查对象，研究园林植物多样性，结果表明：该区道路绿地共栽植园林植物30科52属86种，一级、二级和三级道路绿地园林植物多样性Shannon-Wiener指数平均值分别为1．6、1．1、0．7，二级和三级道路绿地的植物多样性指数有待提高。外来物种或品种使用较多，乔木有13种，占道路绿地乔木种类的26．6％；花灌木5种，占花灌木种类的12．5％；宿根花卉3种，占50.0％；冷季型草坪全部为外来种，乡土物种的使用比例有待提高。
以長春高新技術產業開髮區道路綠地為調查對象，研究園林植物多樣性，結果錶明：該區道路綠地共栽植園林植物30科52屬86種，一級、二級和三級道路綠地園林植物多樣性Shannon-Wiener指數平均值分彆為1．6、1．1、0．7，二級和三級道路綠地的植物多樣性指數有待提高。外來物種或品種使用較多，喬木有13種，佔道路綠地喬木種類的26．6％；花灌木5種，佔花灌木種類的12．5％；宿根花卉3種，佔50.0％；冷季型草坪全部為外來種，鄉土物種的使用比例有待提高。

Through investigating the road greenbelt in high -tech industrial development zones of Changchun , the diversity of garden plants were been researched , the result showed that there were 30 families,52 genera and 86 species of garden plants in the road greenbelt .The Shannon-Wiener index of primary , secondary and terti-ary roads were 1.6、1.1、0.7 , separately.Diversity index of secondary and tertiary roads were hoped to im-prove.Alien species were put to used more , there were13 species of arbor , accounted 26.6%of road greenbelt tree species; flowering shrub were 5 species, accounted 12.5% of flower shrubs species; perennial flowers were 3 species, accounted 50.0%; cool -season lawn was all for alien species , percentage of use of native species were hoped to improve .
