摘要
基于1年(观测频率为2小时)的大量观测数据,探讨了深圳市南山区大学城的UHII与PM2.5浓度的关系。结果表明:UHII与PM2.5浓度呈显著正相关;UHII的日内变化规律与PM2.5基本一致;结合交通量的研究分析认为,PM2.5与UHII呈现相关性的原因是二者都主要来源于机动车排放。
Vehicle emission is a major source of urban air pollution in China. Urban heat island （UHI） effect and PM2.5 concentrations are regarded to be closely related to vehicle emission. UHI intensity （UHII） and PM2.5 concentrations were obtained at University Town of Shenzhen for a year at a frequency of per 2 hours. Re- suits showed that UHII and PM2.5 were significantly positively correlated. The diurnal cycle of UHII had the same pattern as PM2.5. Combined with road traffic volume, the result indicated that the correlation between UHII and PM2.5 concentrations was due to that they were both influenced by their co -source, vehicle emis- sion.
