摘要
采用CMAQ模型系统对珠江三角洲(以下简称珠三角)区域2006年主要大气污染物浓度进行模拟,获得该区域主要污染物浓度时空分布和大气传输季节变化特征,并结合其它相关研究方法分析长距离传输对珠三角区域空气质量的影响.模型模拟结果揭示了珠三角NO2、SO2、PM10、PM2.5浓度具有秋冬季高、春夏季低的季节变化特征,而珠三角O3浓度的高值出现在秋季.零排放扰动法表明长距离传输对珠三角15个区域监测子站NO2、SO2、PM10和PM2.5浓度平均贡献分别为2.6%、13.9%、24.2%和28.1%,并且秋冬季长距离传输贡献大于春夏季.反向轨迹聚类方法显示珠三角区域代表性站点万顷沙72 h反向控制气团依据其来向可分为沿岸气团、大陆气团、区域环流和海洋气团.万顷沙站点主要污染物小时观测浓度大于150μg·m-3的时段与短距离沿岸气团、短距离大陆气团以及区域环流主导下的污染物传输密切相关.四维传输通量分析结果证实,NO2污染传输通道无法由广东省外延伸至珠三角地区,因此珠三角大气NO2浓度主要来源于广东省内的排放.珠三角在受沿岸气团或大陆气团控制时存在从福建省或江西省一直延伸至珠三角的SO2和PM2.5高通量污染传输通道.因此控制珠三角区域大气污染需考虑区域背景气象条件差异,针对不同污染物采取不同的区域联防联控措施.
