To fulfil the"setting up market regulations"function, the government usually applies legal means, administrative means and preceptoral means; to fulfil the"adjusting distribution of incomes"function, the government mainly employs legal means and economic means, while occasionally uses political means and administrative means when necessary; to fulfil the "maintaining macro economic stability"function, the government mainly makes use of economic means and administrative means though legal means also can not be ignored; when the"coordinating external economic relations"function is carried out, the role of political means is very prominent, the effect of administrative means is very outstanding while the ability of economic means is relatively limited.

We used NCAR/NCEPT anew analyze data and the method of bilinearity insert to fix on profile distribution of several physical field in the air on observation point and the stream field of 700hPa. We primary discussed the possible mechanism to influence aerosol size distribution.The atmospheric condition of 1000hPa~700hPa level had great influence on aerosol size distribution, and influence on coarse particle mainly below 850hPa level. The horizontal wind velocity of 925hPa level is a primary gene which contributed to coarse particles in the air. Vorticity profile especially below 700hPa level is a key gene to influence diffuse and convergence of local aerosol. The air vertical motion velocity greatly influenced aggregation and remove of aerosol particles. The vertical distribution of air temperature mainly influenced vertical transportation of aerosol.
