| 摘 要： | 本文分析了杭州市区2002年至2006年的空气质量资料，结果表明杭州市区首要污染物为PM10。PM10和PM2.5有明显的季节变化和“双峰型”日变化。PM10浓度与天气系统相关性研究表明，在高压控制时容易出现高浓度的污染，在东风带系统出现时PM10的浓度较低。在较长时间的稳定天气条件下霾、轻雾等天气现象对PM2.5、PM10的影响很大。

| Abstract: | The paper analyzes air quality data of Hangzhou urban area from 2002 to 2006,the results show that the Premier pollutant is PM_(10) in Hangzhou urban area. There are signifificant seasonal variations and "bimodal type" daily varietions of PM_(10) and PM_(2.5).The study of relationship between PM_(10) concentration and weather system indicates that the peak concentration pollution easily appeared under the high-pressure control system,and PM_(10) concentration is relatively lower under the easterly system.The weather phenomenon as the haze and mist exist tremendous influence on PM_(2.5) and PM_(10) under a long-time stable weather condition. |
