| 摘 要： | 为全面掌握中国细颗粒物（PM2.5）的污染现状水平及空间分布格局,本文运用统计学、空气质量评价规范、聚类分析方法对全国74个城市2013年的监测数据进行分析,结果表明：①目前中国PM2.5污染程度整体较重,74个城市中仅有拉萨、海口和舟山3个城市达到年均值二级标准,邢台、邯郸和石家庄3个城市PM2.5的超标天数比例超过70%;②PM2.5浓度季节变化特征大体表现为冬季>秋季>春季>夏季,重度及以上污染主要集中在12月和1月;③从浓度水平来看,沿海城市总体优于中部内陆地区,污染最重的区域主要分布在河北南部地区;④受城市经济发展水平、产业结构、气候、地形等多因素影响,全国PM2.5污染状况区域特征明显。 |

| Abstract: | Based on statistics,regulation for ambient air quality assessment,cluster analysis and GIS we analyzed monitoring data for 74 cities in 2013 in order to understand the current pollution status and spatial distribution pattern of PM2.5 in China. We found that PM2.5 pollution in China was serious on the whole,and only three cities （Lhasa,Haikou and Zhoushan）could comply with the Grade Ⅱ national air quality standard. Three cities’ （Xingtai,Handan and Shijiazhuang）proportions of days exceeding standard were more than 70%. The seasonal variety of PM2.5 concentration was generally winter > autumn > spring > summer. The times of severe pollution were mainly concentrated in December and January. The concentration of pollutants in these regions often showed a wide range of pollution,and had characteristics of accumulating rapidly,long duration and severe degree of contamination. According to the PM2.5 concentration,coastal cities were lower than the interior regions in central China,and the most polluted area was mainly distributed in the southern region of Hebei. Affected by the level of economic development of the city,industrial structure,climate and topography and other factors,the pollution status of PM2.5 in China has obvious regional characteristics. However,the characteristics and causes of pollution in these regions require further research. Only the first 74 cities were used to monitor PM2.5 in this study,which means a relatively small time span and coverage. With more and more cities monitoring in the future,we will be able to conduct pollution research at a national scale. |
