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。

关键词: 可吸入颗粒物(PM10) 高压控制 东风系统 霾

Abstract:

The paper analyzes air quality data of Hangzhou urban area from 2002 to 2006 , the results show that the Premier pollutant is PM10 in Hangzhou urban area. There are signifificant seasonal variations and " bimodal type " daily varietions of PM10 and PM2.5 . Ihe study of relationship between PM10 concentration and weather system indicate that the peak concentration pollution is easily appeared under the high_pressure control system, and PM10 concentration is relatively lower under the easterly system . The weather phenomenon as the haze and mist exist tremendous influence to PM2.5 and PM10 under a long-time stable weather condition.

Key words: inhalable particle materials(PM10 ) high_pressure control system  easterlies system haze
