摘    要:交通绿化带有显著的净化街道空气的环境效益。通过对上海浦东某交通干道旁侧绿化带不同季节大气中总悬浮颗粒物(TSP)的测定,定量研究了绿化带对TSP的净化效益;同时对研究区域内植物的配置情况用郁闭度和疏透度进行了表征,并研究了其与TSP的净化效益之间的相关性。研究结果表明:交通绿化带对由机动车引起的TSP污染有明显的净化作用,其中夏、秋季净化百分率较高,春、冬季较低;为达到较高的TSP净化效益,交通绿化带宽度应不小于5m,最佳为10m,采用先灌后乔的配置方式,并更多的选用常绿树种;绿地对TSP的净化百分率同植物群落的郁闭度成正相关,同疏透度成负相关关系;绿地内植物郁闭度的最佳范围为0.70~0.85,疏透度的最佳范围为0.25~0.33。研究结果可为评价现有交通绿化带植物配置情况和日后的城市绿地规划和建设提供技术依据。

关 键 词:总悬浮颗粒物(TSP)  绿地  郁闭度  疏透度  净化效益

Abstract:Green spaces contribute to removal of significant amounts of air pollutants.This quantitive study,using seasonal monitoring data of Total Suspended Particles(TSP) from green spaces along one street of Pudong Shanghai,demonstrates that vegetation can remove large amount of TSP.Furthermore,correlation analysis have been performed between vegetal status measured by canopy density and shelterbelt porosity and TSP removal percentages.The results show:(1) Vegetation in green spaces greatly contributes to reduce TSP pollution.The width of green spaces beside the road should not be smaller than 5m,best is 10m and more evergreen trees should be chosen in order to get a noticeable TSP purification effect.(2) TSP removal percentage is correlated to the canopy density and inverse correlated to shelterbelt porosity.The optimum intervals of canopy density are 0.70-0.85 and shelterbelt porosity are 0.25-0.33.Proposed the optimum intervals can help to estimate vegetation structure of green spaces and provide technical support for programming and construction of urban green spaces.
Keywords:Total Suspended Particles(TSP)  green spaces  canopy density  shelterbelt porosity  removal effects
