摘　　要：以地处安徽省西南部的池州市区为试验区,选取测试点,观测、对比不同植被类型的降温滞尘效应。结果表明,城市绿地具有明显降温滞尘效应,在气温上,裸地变化幅度最大,草地次之,灌草变化较小,乔灌草变化幅度最小,乔灌草调节温度能力最强,最具优良的降温效应;在滞尘方面,乔灌草型的滞尘效果最好,其次是灌草型和草地,并表现出道路绿地的滞尘效应优于公园绿地和住宅绿地。通过对不同植被类型的降温滞尘效应探究,以期为城市绿地的规划与建设提供理论依据。Taking Chizhou City,which was located in the southwest of Anhui Province as the test area,test points were selected to observe and compare the temperature and dust retention effects of different vegetation types.The results of the study showed that urban green space had obvious cooling and dust retention effects.In terms of air temperature,the variation range of bare land was the largest,followed by that of grassland,and that of shrub and herbaceous plants was small,while temperature variation range of shrub and herbaceous plants with arbors was the smallest,and this kind of plants arrangement had the strongest ability to adjust temperature and the best cooling effect.In terms of dust retention,the effect of the shrub and herbaceous plants with arbors was the best,followed by shrub and herbaceous plants and grassland,and the results also showed that the dust retention effect of the road green space was better than that of the park green space and the residential green space.The cooling and dust retention effects of different vegetation types were studied in order to provide some theoretical basis for the planning and construction of urban green space.
