| Abstract: | The dynamic issues of urban atmospheric pollution are the core of the research on urban atmospheric pollution mechanisms and principles for improving. The multi scale interaction of processes in the urban atmosphere, the effect of building blocks and their surrounding landform, the effect of the underlying surface and land surface processes on the urban atmospheric dynamic structure, the cross sphere interactions caused by urban water soil air pollution, etc., are discussed. A comprehensive analysis is given on the dynamic characteristics and impacts of urban atmospheric pollution. Based on these theoretical discussions, the design and implementation of the BECAPEX field experiment and the structure of "big canopy" are described. |
