Territorial Features of Atmospheric Environment in Beijing and Impct of Dust-storm

The territorial features of the amospheric environment in Beijing were described in described in detail,and the transportation pathways of the atmosphere pollutants found by the dot aggregation in the form of the meshwork.The concept on convergence belt of the atmosphere pollutants was given.The vertical distribution of the atmospheric pollutants in Beijing was detected by the neighboring areas of Beijing.The sand-dust storm in China were studie by both satellite inspection technology and analysis of atmospheric flow fields,According tp tje dostrobitopms of sand-dust storm sources to impact on the air environment in China,the sand-dust sources insia were situatad in the desert and Gobi in the Inner Mongolia and Xinjiang autonomous regions .The sand-dust surces outside China were situated in the desert and Gohi in Russina,Hazakhsten and Mongolia.A very strong sand-dust storm taken place on the 20th Mar,2002 is given as exa-mple.

The territorial features of the atmospheric environment in Beijing were described in detail, and the transportation pathways of the atmosphere pollutants were found by the dot aggregation in the form of the meshwork. The concept on convergence belt of the atmosphere pollutants was given. The vertical distribution of the atmospheric pollutants in Beijing was detected by the laser techniques, showing an interrelationship between the quality of atmospheric environment in Beijing and the pollution sources in th...
