根据西宁市1985--2009年的城市用地情况，分别用城市扩展强度和扩展速度指标分析各阶段城市用地扩展特征，利用城市扩展图分析近24a来城市的主要扩展方向，同时利用扩展弹性系数对用地扩展合理性进行分析。结果表明：城市用地规模不断扩大；不同时期城市用地扩展强度和速度差异很大，且呈波动变化；城市用地扩展和人口增长不协调造成城市建设用地紧张。通过用地扩展影响因素分析，经济增长、人口增长、自然地理环境、交通、政府决策等因素影响着城市扩展的速度和方向。

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 laud. 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.
