【摘要】 围绕复杂地形区域尺度大气污染物的扩散问题,以贵州西部山区“西电东送”大型火电厂六枝电厂所在区域为例,采用局部嵌套的高分辨率复杂地形大气扩散模式系统模拟了该区域大气边界层气象场和污染物散布的浓度场,给出各级保证率的小时平均和日均浓度分布,进而得出其年均浓度分布,分析其时空分布及变化特征,研究了山区复杂地形上大气污染物的扩散特性和散布规律。更多还原

【Abstract】 Surrounding the topic of regional scaling air pollutant dispersion over complex terrain,the diffusion characteristics for the relese of LIUZHI plant are investigated in the western region of GUIZHOU province where this coal-fired power plant of the West-East Electricity Transmission Project is situated.The meteorological fields and concentration fields in this area are simulated with a coupled,high resolution atmosphere diffusion modeling system suitable for mountain complex topography.Hourly average concentration,daily average concentration under various given guarantee and annual average concentration are then obtained.Their temporal and spatial characteristics are analyzed too.And then some of the features of diffusion and distribution rules of air pollutant over mountainous terrain are summarized.更多还原
