英文摘要With the fast urbanization of beijing city, the dimension of the city has largely expanded during the past 10 years, so many areas outside the third ring road of beijing city have greatly changed from outskirts to inner city. many higher buildings were set up in the original inner city, which lead to a remarkable increase of the ground roughness in beijing. based on the statistic analysis of the average data measured at the beijing 325 m meteorological tower in 1994 and from 1997 to 2003, we have reached several significant conclusions. firstly, the direction of the wind became more and more disordered on the surface layer which is strongly impacted by the underlying surface. nowadays the wind field cannot reflect the characteristics of inhomogeneous underlying surface of suburb but of the inner city. secondly, its summer mean speed is decreasing yearly below 63 m. and the nearer the earth's surface, the more remarkable decreasing trend was. a conclusion is drawn in this paper that the data of the tower below 47 m reflect the characteristics of urban canopy layer, and the height of the urban canopy layer may reach 47 m to 63 m. finally, though the mean wind has a yearly decreasing trend with fast development of beijing city, the influence on the gust is not obvious and the decreasing trend of the maximum wind speed does not exist below 47 m.
