摘要
随着城市化进程的不断推进,空气污染问题日趋严重。行道绿篱植物作为城市绿化的重要组成部分,具有改善空气质量等多种功能。以河南省洛阳市为研究区域,选取不同区域的5种常见行道绿篱植物,测定其相对含水量、叶提取物pH值、总叶绿素质量分数、抗坏血酸质量分数等4项指标,综合评价其空气污染耐受指数,分析行道绿篱植物滞尘能力与植物空气污染耐受能力间的关系,为洛阳市及其他地区行道绿篱植物的选择提供有益的参考和科学依据。结果显示:5种常见行道绿篱植物的空气污染耐受指数表现为红花檵木(8.81)>红叶石楠(8.79)>大叶黄杨(8.66)>小叶女贞(8.32)>南天竹(8.25)。这表明红花檵木和红叶石楠这2种植物可作为空气污染严重地区的耐受植物,而南天竹因空气污染耐受能力较低,可作为反映空气污染情况的生物指示器。
With the accelerated urbanization process,Air pollution is becoming increasingly se-vere.As an important part of urban greening,roadside hedge plants are considered as one of most ef-fective passive method for the deposition of urban particulate matters with various size fractions.In this study,Study areas were set in Luoyang city and five common roadside hedge plants were se-lected as tested plant species,four biochemical paraments including relative water content(RWC),leaf extract pH,total chlorophyll content(TLC),and ascorbic acid content(ACC)were measured,which intended to comprehensively evaluated their air pollution tolerance index(APTI),besieds,the relationship between the dust retention capacity of the roadside hedge plants and the air pollution tol-erance ability were also discussed.The results demonstrated that the air pollution tolerance index of the tested plants ranked as follows:Loropetalum chinense var.rubrum Yie(8.81)>Photinia serratifo-lia(8.79)>Buxus megistophylla H.Lév.(8.66)>Ligustrum quihoui Carrière.(8.32)>Nandina domestica Thunb.(8.25),his indicates that L.chinense var.rubrum and P.serratifolia are suitable for heav-ily polluted areas due to their high APTI values,whileN.domesticaThunb.can serve as a bioindicator of air pollution owing to its low APTI and high sensitivity.
