摘要
利用2002—2008年哈密环境监测站监测资料和气象站同步观测资料,对哈密市大气污染物浓度分布特征和成因进行研究,结果表明:可吸入颗粒物是影响哈密市空气质量的主要因子,是首要污染物;冬季和3、4月污染最严重,夏季最轻;污染源以煤烟型、风沙型为主;气温日较差、辐射、风、相对湿度、能见度等气象因子与首要污染物浓度变化存在密切关系,气温日较差、日净地表辐射越大、能见度越好,越有利于污染物的扩散和稀释,空气质量就越好。
Based on the environmental monitoring data and meteorological observation data obtained from environmental monitoring station and meteorological observation station from 2002 to 2008 in Hami,the pollution distribution characteristics and the reasons for pollution were analyzed.The result showed that the principal effect factor of air environment in Hami is respirable particulate matter,which is the chief pollutant of Hami,and air pollution is the most serious in winter and Mar.-Apr.,the most trivial in summer;the primary types of air pollution are soot and windblown sand;the chief pollutant concentration is closely related to meteorological factors such as daily temperature range,radiation,wind,relative humidity and visibility etc.,the more the daily temperature range and daily net terrestrial radiation,together with the more visibility,the better the pollutant diffusion and dilution,and the air quality becomes better.
