治霾是一项长期的艰巨任务,需要标本兼治。有效的治本措施主要是调整能源结构,控制污染源,而城市局地微气候的改善也有助于在漫长的治本过程中减少灰霾侵袭。针对具体城市,风道规划建设是不是合理,可以在多大程度上改善城市微气候,能否有效辅助治理灰霾,还存在很大的研究空间与实践距离。只是,面对复杂而且无法回避的问题,各种有意义的尝试都是值得鼓励的。 It is a long-term and arduous task to tackle haze and it needs to tackle both the symptoms and the root cause. Effective remedies are mainly to adjust the energy structure and control the sources of pollution. The improvement of the local microclimate in urban areas also helps to reduce the haze invasion in the long run. For specific cities, the air duct planning and construction is not reasonable, to what extent to improve the urban microclimate, can effectively help control haze, there is still a great deal of research space and practice distance. Only in the face of complex and unavoidable problems, all kinds of meaningful attempts are encouraged.
