摘　　要：根据郑州市1980-2007年能见度及同期地面气象要素(风速、温度、气压和相对湿度)观测资料和2006年、2007年空气污染物(SO2、NO2、PM10)监测数据,分析了郑州市大气能见度的变化特征以及大气能见度与气象要素和空气污染之间的关系。分析表明,大气能见度呈逐年下降趋势。一年之中,能见度最小值出现在12-1月及7-8月,最大值出现在5-6月;一日之中,08时能见度最差,14时最好。能见度与温度、风速呈正相关,与气压、湿度呈负相关,与空气污染物质量呈负相关。Based on the data of the atmospheric visibility, the ground meteorological observation （wind velocity, temperature, pressure and relative humidity） from 1980 to 2007, and the monitoring data of the air pollutants （SO2, NO2, PM10 ）, the paper analyzes the variety characteristic of the visibility and its influence with the weather elements and the air pollution. The result shows the atmospheric visibility is a significant descent trend. The minimum visibility occurs primarily in Dec to Jan, and in Jul to Aug. The maximum visibility occurs primarily in May to Jun. The daily variation of visibility is 08＇ 〈02＇ 〈 20＇ 〈 14＇. The visibility has positive correlation with temperature and wind velocity, while it has negative correlation with pressure and relative humidity. The visibility and the quality of air pollutants were negatively correlated.
