摘要: 利用河西走廊东部武威市1991-2003年春季污染浓度资料和1971-2003年气象要素资料, 分析污染物浓度与各种气象要素和非气象要素的关系, 找出造成河西走廊东部春季污染严重的气候成因, 并提出大气污染治理对策。结果表明, 春季3~5月沙尘暴发生日数和颗粒物污染资料两者有很好的正相关关系, 相关系数达0.8, 沙尘暴天气是造成河西走廊东部春季空气重度污染的主要原因。

Abstract: By using spring pollutant thickness data of 1991—2003 and meteorological factors data of 1971—2003 in Wuwei City, relations of pollutant thickness to various meteorological factors and non-meteorological factors are analyzed. It is concluded that the air TSP concentration in Wuwei City has close positive correlation with the sandstorm occurring days in the east of Hexi Corridor, and the correlative coefficient is higher up to 0.8. The special climatic and geographical environment of eastern Hexi Corridor makes the Wuwei City be the sandstorm highly-frequently occurring region. It is to say that the natural source from sand-dust storm is the principle influencing source of spring air quality. Analysis on relation between human activity and air pollution further indicates that the human-inducing destroy to nature has deteriorated the eco-environment and triggered sandstorm, and then aggravated the air pollution degree.

Key words: sandstorm, air pollution, spring, causes, prevention measures
