摘　　要：Effects of different plantdeployment models was surveyed in urbangreen areas in Huaian Municipality ofJiangsu Province, China. Results indicatedthat all trees and other plants aresignificantly effective in bacteria controlacross all seasons. The significance ofbacterial-control effectiveness is in an orderof within-forest > outside-forest (5 m fromthe stand boundary) and multi-layer >single layer (pure stand). Conifer speciesare more effective, small trees > shrubs inthe green island (isolation island). Theaverage effectiveness in bacteria control ishigher within than outside forest. Theseresults provide scientific evidence fordevelopment of ecological and healthyurban green areas.Effects of different plant deployment models was surveyed in urban green areas in Huaian Municipality of Jiangsu Province, China. Results indicated that all trees and other plants are significantly effective in bacteria control across all seasons. The significance of bacterial-control effectiveness is in an order of within-forest 〉 outside-forest （5 m from the stand boundary） and multi-layer 〉 single layer （pure stand）. Conifer species are more effective, small trees 〉 shrubs in the green island （isolation island）. The average effectiveness in bacteria control is higher within than outside forest. These results provide scientific evidence for development of ecological and healthy urban green areas.
