摘　　要：以2006—2010年的烟台城区PM10监测数据及同期烟台市气象数据为依据,采用ArcGIS分析其时间、空间分布,研究几种气象因素对PM10分布的影响。发现PM10浓度呈现出春、冬季较高,夏、秋季较低的变化趋势,但各区域PM10的变化有一定的不同。在空间上,PM10表现出了一定的污染集中性,且其污染的中心随季度不同会出现移动。烟台城区内PM10浓度分布与风速、湿度具有一定的相关关系,而与气温的关系为非线性。Based on the monitoring data of PM10 concentration from 2006 to 2010 in Yantai,the distribution features and the relationship between PM10 and meteorological elements were studied.The results demonstrated that： the concentration of PM10 maintained at a low level in Yantai but some parts have a little different.The distribution maps of PM10 showed that it had the characteristics of concentration.The high-polluted region were near station 3 and the center of the pollution would move with the different quarter.The main meteorological factors of PM10 concentration is wind and humidity.
