摘要
根据2017—2019年克拉玛依市生态环境局5个监测点监测的克拉玛依辖区内PM_(2.5)质量浓度数据,结合同期克拉玛依国家基本气象站观测的气溶胶及相关气象数据,利用统计分析的方式结合图表直观展示了克拉玛依PM_(2.5)质量浓度的时空变化特征,并重点分析了持续性雾霾天PM_(2.5)日平均浓度变化。结果表明克拉玛依这3 a整体空气质量优良率高,月平均逆温层厚度大致呈U型变化,与PM_(2.5)浓度变化趋势大致一致。另外,克拉玛依PM_(2.5)浓度与逆温层厚度呈显著的正相关,与逆温层强度呈负相关,与逆温层高度没有显著的相关关系。
According to the PM_(2.5)mass concentration data monitored by five monitoring points of Karamay ecological environment bureau from 2017 to 2019,combined with aerosol and related meteorological data observed by Karamay national basic meteorological station in the same peri-od,the temporal and spatial variation characteristics of PM_(2.5)mass concentration in Karamay were intuitively displayed by means of statistical analysis and charts,and the daily average PM_(2.5)mass concentration in persistent haze days was mainly analyzed Concentration change.The re-sults show that Karamay has a high overall air quality excellence rate in the past three years,and the monthly average inversion layer thickness is roughly U-shaped,which is roughly consistent with the change trend of PM_(2.5)concentration.In addition,the PM_(2.5)concentration in Karamay has a significant positive correlation with the thickness of the inversion layer,a negative correlation with the strength of the inversion layer,and no significant correlation with the height of the inversion layer.
