【摘要】 本文以2011~2013年四子王旗空气中颗粒物的浓度和气象监测数据资料为基础,对空气中PM10浓度、TSP浓度、降水、风速等气象因素的关系进行分析,主要结果如下:2011~2013年,TSP浓度和PM10浓度有所下降。且每年4月份为全年最高值。2011~2013年PM10平均浓度分别为:0.265mg/m3、0.236mg/m3和0.224mg/m3。2011~2013年中,我们可以明显看出每年的3~4月份TSP浓度和PM10浓度值呈上升趋势,4~5月份下降趋势。根据国家环境空气质量标准,四子王旗达到一级标准的天气占27.2%,达到二级标准的天气占37.1%,达到三级标准的天气占36%。四子王旗沙尘天气的发生与各种气象因素都有一定关系。TSP浓度值、PM10浓度值受同期风速,降水影响比较明显,根据四子王旗的各种气候特征,对四子王旗防治沙尘天气提出一些建议。更多还原

【Abstract】 This article Based on the 2011- 2013 Siziwang Banner concentration of particulate matter in air and weather monitoring based on the data of PM10 concentration in the air,the TSP density,the relationship between the meteorological factors such as temperature,precipitation,wind speed were analyzed,and the main results are as follows: TSP and PM10 concentrations in 2011- 2013 have decreased and every year in April is the highest for the whole year. Average concentration of PM10 density in 2010- 2013 respectively:. 0. 265 mg / m3,0. 236 mg / m3,0. 224mg/m3. In 2010- 2013,we could clearly see that concentration in every 3- 4 month is on the rise and 4- 5 month is in decline. According to the National Ambient Air Quality Standards,Siziwang Banner can satisfy a standard weather accounted for 27. 2%,two standard weather accounted for 37. 1%,and three standard weather accounted for 36%. The occurence of sandstorm has a certain relationship with various meteorological factors. The same period of the wind speed and precipitation have obvious effect on PM10 concentration and TSP concentration. According to the various climatic characteristics of Siziwang Banner,for prevention of dust weather of Siziwang Banner some suggestions.更多还原
