| At present,particulate matter has become the primary pollutant of urban air pollution in China.The amount of industrial dust and dust in the particulate pollutants is decreasing year by year,while the proportion of particulate matter from dust in the total amount of particulate pollutants is increasing year by year.At present,it has become the primary factor of urban particulate pollution.General secretary Xi Jinping pointed out: "we need to have beautiful scenery and Jinshan Yinshan.It’s better to have green water and green mountains than golden mountains and silver mountains,and green water and green mountains are golden mountains and silver mountains.".With the improvement of people’s living standards,the implementation of national energy conservation and emission reduction policies and the acceleration of urban ecological construction process in China,higher requirements are put forward for urban air quality.In many parts of our country,dust pollution is very painful.Although more efforts have been made to prevent and control dust pollution in many places,many of them are "headache,foot pain,foot pain",which is difficult to care about for a long time.Based on the externality theory,new public management theory and sustainable development theory of environmental pollution,and on the basis of summarizing relevant research literature,taking city a as an example,this paper analyzes the implementation status,existing problems and causes of dust pollution control policies in city a through the sorting of text materials and questionnaire survey of dust pollution in city a,and puts forward targeted suggestions The countermeasures are put forward.Through the questionnaire survey,it is found that there are still some problems in the governance of urban dust pollution in city a,such as less legislative norms,weak law enforcement,lack of unified and effective regulatory mechanism,further optimization of dust pollution control measures,strong willingness of public participation,but insufficient action.On this basis,in-depth analysis of the reasons for the proposed governance countermeasures laid a good foundation.For the treatment of urban dust pollution,whether Luohe City,Ganzhou City,Langfang City,or Los Angeles City and London City abroad,provide a lot of reference for the treatment of urban dust pollution in China.For example: further strengthen the environmental legal system,improve the legal level of environmental protection work;implement the environmental protection target responsibility system,form the environmental protection work force;strengthen environmental governance,actively explore new ways of environmental protection,etc.Urban dust control is a long-term and arduous work,but also with the development of the times and constantly changing.Therefore,on the basis of theoretical analysis and investigation,this paper puts forward the government countermeasures from the aspects of strengthening the establishment of legal basis,establishing and improving the dust pollution control mechanism,strengthening the dust pollution emission control measures and fully guiding the public participation. |
