摘要
使用CALPUFF空气质量模型模拟分析罗源湾的特殊地形及工业布局对罗源湾区域空气质量的影响,分析结果表明:受特殊地形影响,罗源湾区域内近地风场容易形成局地环流,区域内大气污染物不易扩散;模拟区域内大气污染物SO_2、NO_2最大日均浓度、最大小时浓度存在超标情况,超标区域主要集中在罗源湾北岸金港组团。模拟结果显示,罗源湾区域工业布局过于集中,尤其是北岸钢铁企业密集使得局地已经出现污染物浓度超标现象,建议要加快优化罗源湾区域的工业布局和加强罗源湾区域大气污染物排放量的总量控制。
Based on CALPUFF model,the simulation analysis of the effect on regional air quality by special terrain and industrial distribution in Luoyuan Bay was carried out. The result showed that the surface wind would form a regional circulation,which was resulted from the special terrain in Luoyuan Bay Area,not conducive to dispersion of atmospheric pollutants. The maximum daily concentration and the maximum hourly concentration of SO_2 and NO_2 in the simulating region exceeded the air quality standard. The pollution was mainly concentrated in Jin-gang group located in north bank of Luoyuan bay. The excessively dense distribution of iron and steel enterprises created pollution in north bank of Luoyuan bay. According to the conclusion,the optimizing industrial distribution and reducing emission of air pollutants in Luoyuan bay need be accelerated.
