Abstract:As one of the three largest economic hubs in China, the Yangtze River Delta (YRD) experiences serious air pollution due to the huge energy consumption and large emissions. In order to quantify the primary air pollution transport among cities in the YRD region, the Calpuff model, together with the regional emissions inventory of 15 cities and MM5 meteorological simulation, were applied to calculate the primary air pollution transport among cities in the YRD. Shanghai, Suzhou, Wuxi and Changzhou, which are all located along Taihu Lake, comprise the most severely polluted area in the region due to local emissions. In January, with the prevailing wind direction from the northwest, the cities of Jiaxing, Huzhou, Hangzhou and Shaoxing in northern Zhejiang province will be influenced by emissions from the northern cities. On the other hand, in July, with the prevailing wind direction from the south, the cities of Yangzhou, Taizhou and Nantong in central Jiangsu province will be affected by emissions from the southern cities. The results also show that local emissions are a major contributor to the primary pollution of a city, with SO2 61%, NOx 80% and PM10 76% in cities like Shanghai, Nanjing and Hangzhou. In January, cities with heavy influence of outside emissions include Zhoushan, Zhenjiang, Jiaxing and Shaoxing, with the total transport contribution rate of SO2>56%, NOx>40% and PM10>44%. In July, cities like Zhoushan, Nantong, Yangzhou, Taizhou and Huzhou will be greatly influenced by outside emissions, with the total external contribution rate of SO2>66%, NOx>46% and PM10>53%. In summary, the transboundary primary air pollution in the YRD is quite significant, which provides conditions for the formation and aggravation of the secondary air pollution. Synergistic control of air pollution at the regional scale is urgently needed.
Keywords:Yangtze River Delta  Transboundary air pollution  Interaction between cities  Calpuff model
