摘　　要：基于普遍调查数据的城市道路绿化带木本植物结构特征的量化测度,采用物种相对多度分布模型(Ranked—abundance list)、生物多样性指数Simpson指数、物种重要性指数相对多度Ra和物种重现率Rr、物种线密度Lsr进行测度。以徐州市鼓楼区城市道路绿化带为例,实际测定结果表明,综合运用这些测度指数,可以较为全面地反映出城市道路绿化带的整体植物结构特征。A study was performed to quantitatively measure the structural characteristics of xylophyta in urban road greenbelt in terms of species ranked abundance list, biodiversity index （ Simpson index）, species importance index （ relative abun- dance R, ）, species reuse rate （R,） and linear species richness （L.r） based on general investigation. The road greenbelts of Gulou District in Xuzhou were taken as an example. The measured result demonstrates that comprehensive application of these indexes can synthetically reflect the structural eharacteristles of the entire plants in urban road greenbelts.
