摘要
以河南省８个主要城市为研究对象，通过多年监测结果，分析了各城市大气污染的时空变化规律，并应用灰色聚类的方法，对８个城市的大气环境质量进行了评价。结果表明：各城市ＳＯ２处于环境质量二级标准之内；ＮＯｘ大多不超过一级标准；ＴＳＰ是大气污染的主要物质；南阳、开封、平顶山大气环境质量较好。
Eight citys in henan province took as study.base on monitoring data, disstribution lawof air pollution in various city were analysed. and applying method of gery cluster,air qualityin eight citys was evaluated.the results show that concentration of air SO2 was below seconddegree of standard of air quality, NOx under first degree.and TSP was min air pollutant.
