中文摘要	为了探究一带一路重要节点中典型绿洲城市的扩张特征,该文以乌鲁木齐市为例,应用DMSP/OLS夜间灯光数据和统计数据,采用二分法提取建成区范围,选取扩张速度、紧凑度、分型维数、城市扩张弹性系数等指标,运用扇形分析、同心圆分析等方法,探究典型绿洲城市扩张的时空特征;结合统计数据等分析城市扩张的驱动机制。研究结果表明:乌鲁木齐市建成区面积在1993-2013年20年间从64km~2扩张到428km~2,净增约6.69倍。城市扩张经历了由中速到高速扩张,由分散到集中扩张,重心由东向西、由南向北扩张转移的过程。研究发现,在扩张过程中,城市扩张弹性系数从1.96增加至7.93,城市人地关系不和谐程度加剧,城市布局的合理性有待提升,边界趋于简单化。
英文摘要	In order to explore the expansion characteristics of typical oasis cities in the important nodes of the Belt and Road,this paper took Urumqi as a study area,applied DMSP/OLS nighttime light data and statistical data,and used the dichotomy method to extract the built-up area,the indicators of expansion speed,aggregation Index,fractal dimension,and urban expansion elasticity coefficient were used to explore the spatiotemporal characteristics of typical oasis city expansion by using fan analysis and concentric circle analysis.The driving mechanism of urban expansion was analyzed in conjunction with statistical data.The results showed that:the built-up area of Urumqi expanded from 64km~2to 428km~2in the period of 1993-2013,with a net increase of 6.69times.Urban expansion had experienced a medium-to-high-speed expansion,from decentralization to concentrated expansion,with the center of gravity moving from east to west and from south to north.The study found that in the process of expansion,the coefficient of urban expansion elasticity increased from 1.96to 7.93,the degree of disharmony between urban and urban areas increased,the rationality of urban layout needed to be improved,and the boundary tended to be simplified.
