Title: Research on Spatio-temporal Expansion of Urban Land of Xining City
Abstract: Based on the urban land condition of Xining City in the period of 1985 to 2009,adopting the urban expansion intensity index and the pace of expansion of urban land expansion,this paper analyzes land expansion of the city at different stages and the main urban expansion direction in the past 24 years by means of urban expansion graph.Meanwhile,it analyzes the rationality of urban land expansion using elastic coefficient of expansion.The results indicate that the urban land scale of Xining has been expanding,that velocity and intensity of urban land expansion vary greatly and fluctuate at different stages,and that urban land expansion does not coordinate with population growth,resulting in the shortage of urban construction land.The analysis reveals that the speed and direction of urban expansion have been influenced by such factors as economic growth, population growth,geographic and natural environment,transportation and governmental decisions.
