摘　　要：通过对不同配置植物群落的生态效应分析研究,为城市绿地植物的选择、配置、布局等提供有力的依据,并为构建最佳的城市绿地模式进行研究与探讨。在秋冬季节对江苏省淮安市城市街道绿地不同配置模式的植物群落抑菌功能采用自然沉降法测定并计算。结果表明,秋季10月上旬不同植物群落均具有一定的抑菌作用;淮海西路处理2-5(乔木层为大叶榉树Zelkova schneideriana和雪松Cedrus deodara,灌木层为紫荆Cercis chinensis和黄杨Buxus sinica,地被为葱兰Zephyranthes candida)和北京北路处理1-4(乔木层为广玉兰Magnolia grandiflora,灌木层为石楠Photinia serrulata)复层配置植物群落的抑菌效果最佳,抑菌率分别达51.93%和47.10%。合理的植物群落配置的抑菌效果在秋冬季节对改善街道空气质量具有积极意义。To provide basis for plant selection and arrangement on street-side greening in Huai＇an City, Jiangsu Province, the antibacterial effect was conducted on different plant arrangements along streets in autumn of 2006 and winter of 2007. The depositing method by nature and bacteria cultivation of beef-protein medium were adopted. Results showed that the best antibacterial growth on Huaihai West Road was a tree layer of Zelkova schneideriana and Cedrus deodara, a shrub layer of Cercis chinensis and Buxus sinica, and a ground cover of Zephyranthes candida with an antibacterial effect of 51.9%. On Beijing North Road a tree layer of Magnolia grandiflora and a shrub layer of Photinia serrulata revealed an antibacterial effect of 47.1%. Thus, depending on the arrangement, antibacterial effect can improve the urban street-side environment in autumn and winter.
