摘要:

采用番禺大气成分站2007—2013年的能见度、颗粒物(PM1、PM2.5、PM10)及番禺气象局站的相对湿度（RH）资料，对颗粒物7年来的变化状况进行了分析。以RH为标准，将能见度和颗粒物数据分为RH≥90%、80%

Abstract:

Base on the data from 2007 to 2013 of particulate matter and atmospheric visibility of Panyu atmospheric composition station in Guangzhou city ,and the relative humidity(RH) data of Panyu meteorological administration station ,the variation of particulate matter for 7 years were analyzed .The data were divided into three clusters according to RH, RH ≥90%,80%0.57（PM2.5）>0.47(PM10) .When 80%0.46（PM2.5）>0.4(PM10) .While RH≥90%, the correlation was very weak, and no consistent correlation was evident.
