Discussions on Fog and Haze Weather Treatment from Planning View, ---Taking Jinan as Example

摘要

Currently fog and haze weather has become a new kind of meteorological and environmental disaster phenomenon. Taking jinan city as an example, this paper analyzed the causes from planning view. One is the absence of traffic environmental bearing capacity in traffic planning; The second is the lack of sufficient attention to ventilation channel planning; The third is unreasonable layout of industrial land. In order to solve these problems, one hand, we should put forward some city planning countermeasures, such as developing public transit system and paying more attention to bicycle lane and sidewalk planning. On the other hand, it is evitable that automobile possession will increase with economy development, so we should pay more attention on roadway and river course ventilation planning, they are helpful for contaminant spreading by forming an atmosphere favorable to emission diffusion. Moreover industrial land should be laid in upstream of minimum wind frequency and downstream of maximum wind frequency. By these means the fog and haze weather can be controlled to some extent.
