【摘要】：京津冀地區(qū)是霧霾頻發(fā)的典型區(qū),研究該地區(qū)霧霾的時(shí)空分布特征及其規(guī)律,對(duì)防治霧霾意義重大。對(duì)2013年12月至2014年11月的PM2.5數(shù)據(jù)分析表明:1該時(shí)段內(nèi)京津冀霧霾時(shí)空分布差異甚大,秋末至初冬PM2.5濃度值驟然增高,空間范圍由東南向西北不斷地?cái)U(kuò)大。冬末至初春PM2.5濃度值迅速下降,空間范圍由西北向東南不斷縮小。2該地區(qū)處于高壓控制下的低溫、無風(fēng)或風(fēng)力較小的天氣,最易形成霧霾。3第二產(chǎn)業(yè)能耗與PM2.5濃度關(guān)系最為密切,工業(yè)能耗與其關(guān)系最為顯著。4氣象要素是霧霾集聚、轉(zhuǎn)移與擴(kuò)散的重要影響因子,社會(huì)經(jīng)濟(jì)要素是京津冀霧霾頻發(fā)的根本性原因。因此,防治霧霾,應(yīng)該根據(jù)不同時(shí)間段的氣象條件,采取相應(yīng)措施,而調(diào)整能源結(jié)構(gòu)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.
