摘　　要：老旧小区宅旁绿地对空气质量的提升具有重要意义。为探讨寒地城市老旧小区宅旁绿地不同植物配置结构对PM_(10)浓度的影响,以长春市为例,在2020年夏季和冬季对围合式、行列式和混合式楼房布局的老旧小区宅旁绿地内PM_(10)质量浓度及气象因子进行监测。结果表明:1)不同楼房布局监测地之间的PM_(10)质量浓度水平分布和垂直分布基本一致,在日变化中一般呈早晚高中间低;2)冬夏两季不同郁闭度植物配置结构之间PM_(10)质量浓度存在显著差异性,其中郁闭度低的监测地与其他郁闭度高的差异性最显著,PM_(10)质量浓度均为乔灌草结构影响最大,乔灌结构和灌草结构为其次,且多表现为乔灌样地大于灌草和乔灌样地,乔草结构影响最小;3)研究区域PM_(10)质量浓度与温度呈负相关,与相对湿度呈正相关,与风速呈负相关。The green space beside the old residential area is of great significance to the improvement of air quality.In order to explore the impact of different plant configuration structures on PM_(10) concentration in the green space next to houses in old residential areas in cold cities,taking Changchun as an example,PM_(10) mass concentration and meteorological factors in the green space next to houses in old residential areas with enclosed,determinant and mixed building layout were monitored in summer and winter of 2020.The results show that:1)The horizontal and vertical distribution of PM_(10) mass concentration among monitoring sites with different building layout are basically the same,and the daily variation is generally low in the morning and evening,high school and high school.2)There are significant differences in PM_(10) mass concentration between plant configuration structures with different canopy density in winter and summer,among which the difference between monitoring sites with low canopy density and other sites with high canopy density is the most significant.The PM_(10) mass concentration is most affected by the structure of arbor,shrub and grass,followed by the structure of arbor,shrub and grass,and most of them are that the plots of arbor and shrub are larger than those of shrub and grass,the influence of tree and grass structure is the least.3)The mass concentration of PM_(10) in the study area is negatively correlated with temperature,positively correlated with relative humidity and negatively correlated with wind speed.
