- 摘要:
- 以扬州市城区干道绿化树种为试材，研究了滞尘指标以及树种、地段、季节因素等对叶面滞尘效应评价的影响。结果表明：叶片滞尘量测定值在一定程度上可以反映客观环境空气中的颗粒物含量，以文昌路的最大、校园次之、公园最小，其与采样地点的影响密切相关；常绿灌木的叶片滞尘量较大，则表现为对地面粉尘的拦截能力强。因受树种单叶面积大小、树冠密集度、整株叶量多少和叶片组织结构等制约，各滞尘量指标间不尽一致。乔木树种中：单叶滞尘量（mg）与单位面积滞尘量(g/m2) 反映一致，为广玉兰＞悬铃木＞银杏＞枫杨＞女贞＞香樟，干重滞尘量（mg/g）变化较大，为枫杨＞银杏＞悬铃木＞广玉兰＞女贞＞香樟；综合各项指标比较，以落叶树种的滞尘能力占优势，仅广玉兰的单位面积滞尘量表现最高。灌木树种中：单叶滞尘量（mg）、干重滞尘量（mg/g）均以珊瑚树最大，而单位面积滞尘量(g/m2)以小叶黄杨最大。叶片滞尘量的季节性变化与秸秆焚烧等大气污染的动态变化具有明显的相关性，其中：广玉兰以5月值最高，余皆以10月值最高。
- Abstract:
- Taking Yangzhou city road greening tree species as test material，the effects of the dust indicator species，locations，and seasonal factors on the evaluation of foliar dust retention effect were studied.The results showed that leaf dust-retention measurement values to a certain extent can objectively reflect the environmental particulates in the air content，the particulates content of Wenchang Road was the maximum，followed by the campus，the park was smallest，the result was closely related to the impact of the sampling locations；evergreen shrub leaves stagnation large quantity of dust，for the performance of the ground dust interception capability was strong.Dust-retention capacity index was not consistent，because it had many influence factors，such as leaf area，crown of tree density，the amount of whole leaf number and leaf tissue structure.In tree species：the amount of each leaf Dust (mg) and the amount of per unit area Dust (g/m2) was consistent,the result was Magnolia grandiflora>Platanus acerifolia>Ginkgo biloba>Pterocarya stenoptera>Ligustrum lucidum>Cinnamomum camphora，to the amount of dust-dry weight (mg/g) changed greatly，the result was Pterocarya stenoptera>Ginkgo biloba>Platanus acerifolia>Magnolia grandiflora>Ligustrum lucidum>Cinnamomum camphora；compared with the overall index,the dust-retention ability of deciduous tree species was best.Only the amount of per unit area of dust-retention of Magnolia grandiflora linn was the highest.In Shrub species：dust leaf amount (mg)，the amount of dust-dry weight (mg/g) were the largest for Viburnum awabuki，While the unit area of dust-retention(g/m2) for Buxus sinica was largest.Dust species between the amount of seasonal change and straw burning air pollution dynamics has obvious relevance，in which Magnolia grandiflora linn has the highest value in May，others were in October.
