【摘要】 近年来,经济社会的快速发展导致雾霾污染问题较为突出,雾霾污染频频出现在大众视野之中。通过剖析污染物源头控制对雾霾污染防治的作用机理,研究实现我国雾霾防治的根本途径,即如何从源头控制雾霾污染物的产生来有效控制雾霾污染。结果表明:燃烧源和工业源控制在滞后1、2、3期的状态下是雾霾污染程度的格兰杰原因,交通源控制并不是雾霾污染程度的格兰杰原因。同时脉冲响应图显示控制燃烧源、工业源和交通源对我国雾霾污染皆起到一定的抑制作用,从而为我国从"三源"控制角度明确雾霾防治重点和制定防治措施提供了科学依据。更多还原

【Abstract】 In recent years,the rapid economic and social development of many cities in China has led to the problem of haze pollution.The topic of haze pollution frequently appears in everyone’s vision.This paper studies the fundamental ways to prevent and control haze in China,i.e.controlling the production of haze pollutants from the source,by analyzing the mechanism of the control of pollutant sources.The results show that the combustion source and industrial source control in lag periods 1,2,and 3is the Granger cause of haze pollution.The traffic source control is not the Granger cause of haze pollution.At the same time,the impulse response model shows that control of combustion source,industrial source and traffic source for China’s haze pollution has played an inhibitory role,and thus provides a scientific basis for China to make clear the focus of haze prevention and work out control measures from the perspective of controlling the"three sources".更多还原
