Secondly,the influencing factors of haze are explored from the aspects of economic development,energy structure,industrial structure,transportation,etc. The internal driving forces of haze are also researched based on the DPSIR model. Finally some feasible and comprehensive control countermeasures against haze are suggested.展开更多
