| 摘 要： | 利用郑州市区 2003年空气质量日报和同期气象观测资料,分析了郑州市区PM10 ( >10μm可吸入颗粒物)污染状况及相关气象条件变化特征,结果表明:郑州市区PM10污染全年各月均以 2级为主,占总样本数的77. 5%;其次是 3级污染,占 15. 1%, 1级只占 7. 4%。1 ~7月份 3级污染逐渐减少, 8 ~11月份 1级天气占一定比例。全年 3级污染日依自然季节变化逐渐减少。出现≥3级污染日时,空气相对湿度为 61% ~70%的占 3级污染日的 1 /3;日均风速≤2. 0m/s的日数占 3级污染日的 78%。

| Abstract: | The pollution status of PM 10 (particles whose diameter is less than 10mm) and the characteristics of meteorological conditions are analyzed by using the daily reports of atmosphere quality of Zhengzhou City in 2003 and the synchronic meteorological observing data. The result shows that the daily pollution statuses at Grade II occupying 77.5% of all the specimens are majority in every month; the sequent is the statuses at Grade III occupying 15.1%; the statuses at Grade I only occupy 7.4%. The statuses at Grade III are decreasing from January to July and there is a portion of some statuses at Grade I from August to November. Days which status is at Grade III are gradually decreasing according to the season's alternation. When the daily pollution status is at Grade III, there are one third days which relative humidity is between 61%~70% and 78% days which mean daily velocity is less than 2.0 m/s. |
