采用物种相对多度分布模型、生物多样性指数中Simpson指数、物种重要性指数相对多度和物种重现率、物种线密度等指标对徐州市云龙区城市道路绿地木本植物多样性进行测定和分析的结果表明：主要应用的植物有乔木16种，灌木22种；出现频度最高的乔木为悬铃木、国槐、女贞和重阳木，灌木为红叶石楠、金森女贞、蜀桧、大叶黄杨；道路绿化带Simpson指数乔木最高为0．695、灌木最高为0．756；重现率指数乔木为3．45～41．38、灌木为3．45～31．03，相对多度指数乔木为0．25～20．2、灌木为0．02～57．4，物种线密度为1．049—10．405。
採用物種相對多度分佈模型、生物多樣性指數中Simpson指數、物種重要性指數相對多度和物種重現率、物種線密度等指標對徐州市雲龍區城市道路綠地木本植物多樣性進行測定和分析的結果錶明：主要應用的植物有喬木16種，灌木22種；齣現頻度最高的喬木為懸鈴木、國槐、女貞和重暘木，灌木為紅葉石楠、金森女貞、蜀檜、大葉黃楊；道路綠化帶Simpson指數喬木最高為0．695、灌木最高為0．756；重現率指數喬木為3．45～41．38、灌木為3．45～31．03，相對多度指數喬木為0．25～20．2、灌木為0．02～57．4，物種線密度為1．049—10．405。

The wrban road greenbelts of Yunlong district in Xuzhou were measured and analyzed. The results showed that using these indexes synthetically can indicate the structure characteristics of the entire plants in urban road greenbelt much more comprehensively. 16 species of arbor and 22species of shrubs were mainly applied; the highest frequency of arbor specie was Platanus acerifolia and Sophora japonica and Ligustrum lucidum and Bischofia polycarpa. The highest frequency of shrubs specie was Photinia serrulata and Ligustrum japonicum and Sabina komarovii and Buxus megistophyUa. The highest simpson index of roads＇green space was 0. 695 of arbor and 0. 756 of shrubs; the highest reappear rate of arbor was 3.45 -41.38, shrubs was 3.45 - 31.03 ; the highest relative abundance of arbor was 0. 25 - 20. 2, shrubs was 0. 02 -57.4; the highest linear species richness was 1. 049 - 0. 405.
