中文摘要：

文章选取1949—2010年兰州市清真寺的空间矢量化数据，通过应用标准差椭圆法（Standard deviational ellipse，SDE）和重心迁移模型，分析了兰州市清真寺自1949年以来空间格局演变特征及其影响因素．研究结果表明：①清真寺空间分布经历了明显的“集聚-相对分散-分散”的变化趋势，并向西北方向延伸．②清真寺重心表现出由靖远路街道临夏路街道-西园街道的移动轨迹，相比七里河区，城关区清真寺空间变化较为稳定．③清真寺空间格局演化经历三个时期，依次是1949—1978年集中式扩散，1979—1990年跳跃式扩散，1991—2000年、2001—2010年核心-边缘式扩散，并呈倒“T型”模式④其空间演化主要受宗教政策与制度，人口增长与流动、经济发展与转型以及城市规划与建设的共同作用．

英文摘要：

This paper selects the spatial vector data of mosques in Lanzhou City from 1949 to 2010 by applying standard deviation ellipse （SDE） and gravity migration model, and analyzes space layout features of mosque in Lanzhou city and its influencing factors since the year of 1949. The results show that： ①The spatial distribution of the mosque has experienced an obvious tendency of ＂agglomeration- relative dispersion dispersion＂ and stretches northwest. ②The center of gravity of the mosques shows the trajectory of moving from Jingyuan Road to Linxia Road and then to Xiyuan Street,and mosques at Chengguan District presents a relatively stable spatial change compared with that of Qilihe District. ③The evolution of the spatial pattern of mosques has experienced three periods, namely, the period of 1949-1978 featuring centralized proliferation,the period of 1979-1990 featuring Jumping proliferation and the period of 1991-2000 and 2001-2010 featuring core-peripheral diffusion in the inverted ＂T-type＂ model. ④The aforementioned spatial evolution is mainly affected by religious policies and systems, population growth and mobility, economic development and transformation, and urban planning and construction.
