One dusthaze episode occurring from North China to Northeast China plains during 4-6 Nov 2010 has been analyzed, using MODIS data, air pollution monitoring data, weather chart, and backward trajectory method. Preliminary result shows that this dusthaze episode in Northeast China is inherently related to that in North China, and the former is influenced by the transportation of air pollution form the latter. The air pollutant transportation channel between Northeast China and North China is the Bohai Bay and its neighborhood Liaohe Plain. This conclusion was proved by MODIS image, backward trajectory analysis and the phase delay of PM10(inhalable particulate) concentration upspring along the transportation route. This brings forward a challenge to the air pollution regional control strategy.
