The urban atmospheric environment is examined with the air pollutant monitoring data and the daytoday data from the outpatient service of the Nanyang Central Hospital between 2004 and 2005 year, as well as the conventional meteorological data from 1971 to 2007 at Nayang Weather Station. The statistical analysis is conducted of haze weather and air pollution characteristics at Nayang and the influence of haze weather on humanbody health, based on the medical records of the hazerelated outpatient service. The results indicate: there was obvious interannual variation in the number of haze days at Nanyang, and there was an increase trend in either occurrence frequency or duration of haze weather in the recent 37 years; haze weather occurred more frequently in autumn and winter, and the haze weather worsens air pollution, specially when PM10 density increases greatly in haze weather; the clinical rate of respiratory diseases increases obviously in haze weather. The analysis demonstrates that the number of respiratorydisorder outpatients and PM10 density are correlated positively, namely the PM10 density increases along with the increasing respiratory disorder outpatients.
