| 摘 要： | 根据近年来广州市区空气质量监测资料，对广州市空气可吸入颗粒物（PM10）的污染水平、时空变化特征进行了分析、评价。结果表明，2007年广州市PM10平均浓度为0．077mg／m^3，符合国家空气质量二级标准。得益于空气污染控制取得的成效，近5年来PM10年均浓度呈下降趋势。受气候因素影响，PM10污染季节变化明显，冬季节较高，夏季节浓度较低；在空间分布上PM10污染呈现区域性发展趋势。

| Abstract: | On the basis of air monitoring data in Guangzhou in recent years,it analyzed the concentration and temporal and spatial variation of atmospheric PM10.The results showed that the average PM10 concentration in 2007 was 0.077 mg/m3,and it was regular to the second grade in Ambient air quality standard.The average annual PM10 concentration since 2003 was decreased with effective controlling air pollution.In terms of season,the pollution in winter was serious than in summer because of climate element.PM10 pollut... |
