摘要
大气污染区域间的联防联控是解决区域性灰霾产生的关键手段之一。如何确定目标控制区大气污染外源的相对位置和影响程度是实现联防联控的前提。基于后向气团轨迹理论,运用拉格朗日混合单粒子轨道模型,以桂林市全境作为研究对象,对研究区域2013年冬季的污染物传输进行了模拟。结果显示:研究区冬季大气污染主要来源于东北方向,轨迹与"湘桂走廊"相符。以数字矢量图的方式量化表示了大气污染来源区及数量,成果可为区域间大气污染联防联控措施提供决策支持依据。
The zone collective control of air pollution was one of the key means to solve regional haze production.Its premise was to determine the relative position and impact level of the outside sources of air pollution.Based on the backword trajectory theory,using Guilin as the research object,the single-particle orbits hybrid lagrangian model was used to simulate the winter pollutant transport in 2013,the results showed that the pollution was mainly came from the northeast of the study area in winter,the trajectory was in accordance with Xiang-Gui Corridor.Air pollution source areas and its number were quantized by digital vector diagram,the results could provide the decision support basis for zong collective control of air pollution.
