摘要: 利用2004—2010年乌鲁木齐市空气污染物PM10的监测数据,对其评价浓度的时空变化特征进行分析。结果表明:近年来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, PM10浓度表现为采暖期大于非采暖期,采暖期PM10浓度值为国家二级标准平均浓度的2.31倍。城区南部PM10污染重于北部和中部。

Abstract: According to the monitoring data of air pollutant PM10 in Urumqi from 2004 to 2010, the spatial-temporal characteristics of pollutant concentrations were analyzed. The results show that the spatial-temporal characteristics of pollutant concentrations are obvious. The concentration of PM10 is higher in heating periods than in non-heating periods. The concentration value of PM10 is 2.31 times in heating periods than the national standard (the second level). The pollution index is higher in the south than in the north and middle of Urumqi.
