摘要
本文利用大武口、惠农、平罗、陶乐4个大气降尘观测点2007—2016年的监测数据,对石嘴山市的降尘量进行了统计分析。结果表明:平罗县降尘量最大,惠农次之,陶乐处在第三位,大武口降尘量最小。石嘴山市春季、夏季降尘量显著下降,秋季、冬季变化趋势不显著,采暖期降尘量明显小于非采暖期,年平均降尘量具有显著下降的趋势。
By using data for nearly 10 years of 4 atmospheric dust fall observation points in Dawukou District, Huinong District, Pingluo County and Taole Township, this paper analyzed the dust reduction in Shizuishan City. It is found that Pingluo had the largest amount of dust fall, the second was Huinong, while Taole was in the third place, and Dawukou was in the last. The dust reduction in Shizuishan City in spring and summer decreased significantly, and the change trend in autumn and winter was not significant. The dust fall in heating period was obviously less than that in non heating period, and the annual average dust fall volume decreased significantly.
