【摘要】：京津冀地区是雾霾频发的典型区,研究该地区雾霾的时空分布特征及其规律,对防治雾霾意义重大。对2013年12月至2014年11月的PM2.5数据分析表明:1该时段内京津冀雾霾时空分布差异甚大,秋末至初冬PM2.5浓度值骤然增高,空间范围由东南向西北不断地扩大。冬末至初春PM2.5浓度值迅速下降,空间范围由西北向东南不断缩小。2该地区处于高压控制下的低温、无风或风力较小的天气,最易形成雾霾。3第二产业能耗与PM2.5浓度关系最为密切,工业能耗与其关系最为显著。4气象要素是雾霾集聚、转移与扩散的重要影响因子,社会经济要素是京津冀雾霾频发的根本性原因。因此,防治雾霾,应该根据不同时间段的气象条件,采取相应措施,而调整能源结构才是治霾的根本所在。
[Abstract]:The Beijing-Tianjin-Hebei region is a typical area where haze occurs frequently. The temporal and spatial distribution and regularity of haze in this area are studied. The analysis of PM2.5 data from December 2013 to November 2014 showed that the spatial and temporal distribution of Beijing-Tianjin-Hebei haze was very different during the period from December 2013 to November 2014, and the concentration of PM2.5 increased sharply from the end of autumn to the beginning of winter. From southeast to northwest, the concentration of PM2.5 decreased rapidly from the end of winter to the beginning of spring, and the spatial range decreased continuously from northwest to southeast. 2. The low temperature under the control of high pressure, no wind or less windy weather, The energy consumption of the secondary industry and the concentration of PM2.5 are the most closely related to the formation of haze, and the most significant meteorological factor is the concentration, transfer and diffusion of haze, and the most significant meteorological factor is the concentration, transfer and diffusion of haze. Social and economic factors are the fundamental reason for the frequent occurrence of haze in Beijing-Tianjin-Hebei, therefore, the prevention and control of haze should be based on the meteorological conditions of different time periods and take corresponding measures, and the adjustment of energy structure is the fundamental to cure haze.
