Abstract

The mobile surveys were conducted by vehicles equipped with meteorological instruments and GPS in Lanzhou.With the corrected data and the method of spatial interpolation, this paper model urban thermal field in three periods of Lanzhou in summer and analyzed the cause of formation.Results show that the thermal field of Lanzhou presents regular distribution.The thermal space distribution characters have directly relations with land use type, urban energy consumption, population density, building volume rate, and thermodynamic properties of underlying surface.Two automatic meteorological stations were used to observe meteorological elements contrastively at urban area and suburb from 2006 to 2007, combining with the routine meteorological data of urban meteorological station in recent 70 years and the routine meteorological data of suburb station in recent 40 years, large time scale temperature variation, heat island effect, and change of heat island intensity.Results show that interannual variation characteristics of temperature are consistent with the large scale oscillation characteristics in last century; urban heat island effect is more remarkable, and urban heat island intensity has become strong gradually from the 1980s, these characteristics have close relations with development of urbanization and industrialization in Lanzhou.
