杭州常见道路绿化灌木秋季滞尘能力研究

通过实地调查、采样,对杭州道路常见灌木滞尘能力进行测定,浙大路4种灌木滞尘顺序为:红花继木>金边黄杨>红叶石楠>无刺枸骨;教工路5种灌木滞尘的顺序为:无刺枸骨>金边黄杨>紫薇>红叶石楠>红花继木;丰潭路5种绿化灌木的滞尘顺序为:无刺枸骨>紫薇>金边黄杨>红花继木>红叶石楠;汽车西站4种绿化灌木滞尘能力顺序为:红花继木>紫薇>无刺枸骨>金边黄杨;天目山路5种灌木滞尘能力顺序为:紫薇>无刺枸骨>红花继木>红叶石楠>金边黄杨;所选5种绿化灌木,秋季平均单位叶面积滞尘能力顺序为:紫薇>无刺枸骨>红花继木>金边黄杨>红叶石楠,5条道路中,金边黄杨、红花继木、红叶石楠均在汽车西站滞尘能力最强,紫薇、无刺枸骨在天目山路滞尘能力最强。

Study on Dust Retention Capacity of Ordinary Shrubs along Road in Hangzhou in Autumn

The dust retention capacity of ordinary shrubs along the roads in Hangzhou in autumn was determined by surveying and sampling.The order of the dust retention capacity of several shrub species along Zhejiang University Road was: Lorpetalum chindense > Euonymus japonicus > Photinia serrulata> Ilex cornuta var.fortunei,that along Jiaogong Road was: Ilex cornuta var.fortunei> Euonymus japonicus> Lagerstroemia indica> Photinia serrulata > Lorpetalum chindense,that along Fengtan Road was: Ilex cornuta var.fortunei> Lagerstroemia indica> Euonymus japonicus> Lorpetalum chindense> Photinia serrulata,that in Western Bus Station was: Lorpetalum chindense> Lagerstroemia indica> Ilex cornuta var.fortunei> Euonymus japonicus,and that along Tianmushan Road was: Lagerstroemia indica > Ilex cornuta var.fortunei> Lorpetalum chindense > Photinia serrulata > Euonymus japonicus.In autumn,the order of the average dust retention capacity per unit leaf area of five shrub species was: Lagerstroemia indica> Ilex cornuta var.fortunei > Lorpetalum chindense > Euonymus japonicus > Photinia serrulata.Among the five roads,Euonymus japonicus,Lorpetalum chindense and Photinia serrulata had the strongest dust retention capacity in Western Bus Station,and Lagerstroemia indica and Ilex cornuta var.fortunei had the strongest dust retention capacity in Tianmushan Road.
