【摘要】 根据《兰州市大气污染综合防治方案》、兰州国家气象观测二级站2008年全年逐日逐次的实测地面气象数据、环评基础数据应用库中的中尺度高空气象模拟数据及兰州市环境监测站2008年全年逐日监测数据,应用AERMOD模型,估算了供热规划实施和未实施(即零方案)两种方案下采暖期的主要污染物PM10、SO2日均浓度值。结果表明,供热规划实施后,环境空气污染物SO2、PM10贡献值是零方案下的14.5、11.2倍,但占标率还是较高,原因是背景值过高。更多还原

【Abstract】 Based on the Air Pollution Comprehensive Prevention and Control Scheme of Lanzhou City,daily meteorological data of 2008 from Lanzhou National Weather Observing Secondary Station,mesoscale meteorological simulation data from the Environmental Engineering Environmental Quality Assessment Center Simulation Laboratory,and the meteorological daily data in 2008 from environmental monitoring station of Lanzhou and using AERMOD model,the daily mean concentration of SO2,PM10 under two schemes: implemented heating plan and unimplemented heating plan(the zero solution) were estimated.The results showed that,the contribution value of SO2,PM10 after implementation heating plan is 14.5 and 11.2 times compared with the zero scheme.更多还原
