摘要
以2004～2010年乌鲁木齐市空气污染物二氧化硫的监测数据为依据,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,SO2浓度表现为采暖期大于非采暖期,采暖期SO2浓度值为国家二级标准平均浓度的3.45倍。城区南部污染重于北部和中部。乌鲁木齐大气污染的原因,主要有燃煤、地形和气象等因素。为防治乌鲁木齐市空气质量继续恶化,需要采取积极有效的预防措施,切实保护好人类赖以生存的生态环境。
According to the monitored date in Urumqi city from 2004 to 2010, the spatio-temporal change of sulfur dioxide was analyzed. The results showed that the concentration of sulfur dioxide was higher during heating period than that during nonheating periods. Actually the former was 3.45 times of the second level of national standard. The pollution level in south part of Urumqi was higher than that of north part and middle part. The factors affecting the atmospheric pollution in Urumqi contained coal combustion, terrain and meteorological condition. To prevent the atmospheric pollution become worsened to protect the environment where the human live in, effective measures must be taken.
