| 摘 要： | 对2002年1月1日-2002年12月31日日照市环境监测中心提供的PM10(可吸入颗粒物)日平均浓度资料和对应时段的日照市地面气象资料做了深入的分析,揭示了污染物PM10变化特征及其随气象要素的变化规律。同时分析了主要污染物PM10与地面风速、风向间的相关关系,发现日照市大于等于3级的PM10污染日均出现在1-4月,地面风速对污染物PM10浓度有一定影响,当地面风速超过5m/s时,3级及以上污染日很少出现,当地面风速超过6.5m/s时,随着风速的提高,污染物浓度呈下降趋势。污染物浓度呈明显的季节变化,冬、春季节明显高于夏、秋季节。

| Abstract: | Based on the PM10 mean concentration data and surfacemeteorological data during Jan.-Dec.,2002,dalily PM10 variation characters of Rizhao city and their relations with surface wind speed,wind direction are analyzed.Results show that the lightmedium and heavy pollution days(API>100)all occurred in January to April;the PM10 concentration was to some extent correlated with surface wind speed,i.e.when the surface wind speed was greater than 5m/s,the pollution(API>100)was rarely seen,and the pollutions concentration showed a reducing trend when the surface wind speed exceeded(6.5m/s;)and the pollutions concentration exhibited an obvious seasonal variation,and the concentrations in winter and spring were remarkably higher than those in summer and autumn. |
