摘    要:为掌握乌鲁木齐市大气污染时空分布规律,利用近年乌鲁木齐市大气污染物的浓度最新资料,详尽分析了其空气质量的年际变化和空间分布特征。统计了2008年各污染物日、月变化规律。结果表明,近年乌鲁木齐市城区大气污染物质量浓度具有明显时空分布规律,即大气污染物质量浓度冬春季大于夏秋季,PM10和SO2浓度夜间大于白天。在空间分布上,PM10和SO2南部区域最高,中部次之,市区北部最轻,NO2则呈现出由北向南逐渐升高的分布特征。

关 键 词:乌鲁木齐  大气污染  特征  空间分布

Abstract:Based on the latest Urumqi city's air pollution datum in recent years,the characteristics of air quality different years and spatial distribution were analyzed.Each pollutant variation law daily and monthly variation was statistic in 2008.The results showed that the regulation of pollutant for time change and special distribution was obvious.Pollutant concentration was greater in winter and spring than summer and autumn.PM_(10) and SO_2 were highest.The NO_2 concentration increased gradually from north to s...
Keywords:Urumqi  air pollution  characteristic  spatial distribution
