| 摘 要： | 提出了一种利用移动监测技术研究区域大气环境中PM2.5／PM10空间分布的方法，并在2004年12月进行了宁波市全市域PM2.5／PM10空间分布的研究。数据显示：相同路径所代表的地区PM2.5和PM10具有很好的相关性，多数路径上PM2.5与PM10数据的相关系数平方在0．95以上，而不同路径上PM2.5与PM10的比值不同。文中给出了宁波市PM2.5／PM10污染的空间分布图，直观地显示出PM2.5／PM10污染的空间分布情况，突出了污染的重点点位和地区。

| Abstract: | In this paper, a new method for the study on regional ambient PMz.5 and PM10 concentrations spatial distribution using mobile monitoring is introduced. Experiments were carried out to survey the spatial distributions of PM2.5 and PM10 concentrations in Ningbo City in December 2004. Results show that there is a high correlation coefficient between PM2.5 and PM10, with r^2 〉 0. 95 in most routes representing different areas. Ratios of PM2.5/PM10 vary among routes. Spatial distribution maps of PM2.5 and PM10 concentrations are given, from which the key spots and/or areas with significant pollution problems can be figured out easily. |
