摘要:
 在晴朗无风的天气下，采用野外监测的方法，对沈阳市3条街道绿带的PM10、PM2.5质量浓度进行研究。结果表明，1）相同街道分别比较不同林带内外PM质量浓度，只有青年南大街的油松纯林和其对照点有显著差异，说明青年南大街的油松纯林对PM有显著消减作用；其他街道林带内外的PM质量浓度均差异不显著。2）3个不同采样街道中，南堤东路街道对照点的PM质量浓度显著>城市二环和青年南大街的街道对照点；南堤东路的油松纯林、杨柳混交林内的PM质量浓度显著>城市二环和青年南大街的油松纯林和杨柳混交林；而城市二环和青年南大街的对照点、油松纯林和杨柳混交林内PM质量浓度则无显著差异。湿度是主要影响因子。3）在与气象因子的相关性分析中，只有杨柳混交林内的PM质量浓度与温度呈显著负相关关系；南堤东路的油松和杨柳混交林的PM质量浓度与相对湿度无显著相关，其他样地的PM质量浓度与相对湿度均呈显著正相关关系。
Abstract:
 In sunny and windless weather conditions,by using the field monitoring method,PM10,PM2.5 mass concentrations of the greenbelts in three roads in Shenyang were measured and compared,including Qingnian South Road (Q.S.Rd),Second-Ring Road (S.R.Rd),and Nandi East Road (N.E.Rd),in which pure coniferous belt (Pinus tabuliformis) and mixed belt (Populus alba and Salix babylonica) were planted.Bare ground was used as the control.The results were as follows:1) by comparing the PM mass concentrations inside and outside the green belts in the same road,only pure coniferous belt and the control point in Q.S.Rd showed significant differences,indicating that the pure P.tabuliformis could retain PMs.In other roads,no significant differences in PMs were observed within and outside the belts.2) In three sampling roads,PMs in control point in N.E.Rd were significantly higher than those in S.R.Rd and Q.S.Rd.PMs in pure belt and the mixed belt in N.E.Rd were significantly higher than in S.R.Rd.No significant differences in PMs were found between the control points,pure belt,and mixed belt in S.R.Rd and Q.S.Rd.Humidity was the key influencing factor.3) Correlation analysis of meteorological factors indicated that only the PMs in the mixed belt had significantly negative correlations with temperature.The PMs in pure belt and mixed belt in N.E.Rd did not have significantly negative correlations with relative humidity.The PMs in other sites had significantly positive correlations with relative humidity.
