| 摘 要： | 依据吐鲁番市2015年3月—2016年2月的PM_(10)、PM_(2.5)和气象资料,利用统计分析,探讨吐鲁番市PM_(10)和PM_(2.5)浓度的变化特征及其与气象要素的关系。结果表明:冬季PM2.5与PM10浓度的平均值最高(106 ug/m3、184 ug/m~3),春季次之(63 ug/m~3、163 ug/m~3),夏季最低(33 ug/m~3、95ug/m~3),且冬季二者浓度的平均值比夏季分别高大约69%、48%。11月至次年2月,每个月中PM_(2.5)和PM_(10)的污染程度在轻度污染以上的天数相比其它月份较多。PM_(10)与PM_(2.5)的日变化曲线特征呈现"双峰双谷"的特点;PM_(2.5)与PM_(10)的比值在冬季达到了60%~80%,这说明吐鲁番冬季主要以PM2.5污染为主;PM_(2.5)和PM_(10)与能见度之间存在极其显著的相关性,相关系数分别为-0.904、-0.792,与单一气象要素(如相对湿度、风速、温度等)的相关性不明显,但不同气象要素的共同作用对其有显著影响。

| Abstract: | Based On PM10,PM2.5 and meteorological data of Turpan city from March 2015 to 2016 February,the relationship between PM10 and PM2.5 concentration in Turpan and its relationship with meteorological factors were discussed,using statistical analysis.The results showed that the average concentrations of PM2.5 and PM10 in winter was the highest (106ug/m3,184ug/m3),followed by spring(63ug/m3,163ug/m3),the lowest in summer(33ug/m3,95ug/m3), and the average concentration of PM2.5and PM10 in winter was about 69%and 48% higher than in summer.November to February the following year, the monthly PM2.5 and PM10 pollution levels in the number of days of mild pollution compared to other months more.The characteristics of daily variation curves of PM10 and PM2.5 show the characteristics of "double valleys in Shuangfeng".PM2.5 and PM10 ratio in the winter reached 60% to 80%, which indicated that the main pollution was PM2.5 in Turpan winter.There is a significant correlation between PM2.5 and PM10 and visibility, and the correlation coefficients are-0.904,-0.792, respectively, and the correlation with single meteorological factors is not obvious, such as relative humidity, wind speed and temperature, etc,but the synergistic effect of different meteorological elements has a significant effect on it. |
