基于1982-2010年兰州市街道和乡(镇)层面人口普查数据,运用反距离权重插值和空间关联分析等方法,结合ArcGIS 9.0和GS+7.0等软件对兰州市回族人口空间演化及其社会响应进行了全面分析。结果表明,首先,兰州市回族人口呈一主一次"双峰体"结构,"峰体"之间回族人口不断填充。其次,回族人口空间分布表现出强正相关性,集聚趋势增强,空间结构相对稳定。"热点区"位于老城区,范围不断扩大,且向东西方向延伸;"冷点区"位于老城区外围,范围逐步缩小,且向西偏移。而回族人口增长空间则表现为弱正相关性,空间结构具有明显的随机性和不稳定性。"增长热点区"范围持续缩小,"增长冷点区"范围不断扩大。在此基础上,从传承民族文化,增强城市包容,繁荣城市经济,构建和谐城市4个角度对回族人口空间演化过程的社会响应进行了系统地归纳和总结。
Based on demographic data at a street level from 1982 to 2010 of Lanzhou,the essay analyzes the spatial evolution of Hui population spatial structure and social response in Lanzhou,by a comprehensive application of inverse distance weighted(IDW),spatial correlation analysis and other methods,combined with software ArcGIS 9.0 and GS+Version7.The results show:firstly,the overall distribution of the Hui population shows " double columnar peak body " structure,with a major peak body,another minor peak body,and population is increasing between the two columnar peak body.Secondly,the spatial distribution of the Hui population between neighborhoods showed a strong correlation,and the spatial concentration trend is strengthening.Population spatial structure is relatively stable.Hot spots are located in the old city,and the scope expanded to the east-west direction,but the transition was not apparent phenomenon.Cold spots are located in the old city periphery.The scope is gradually shrinking and westward shift,and cold spots are distributed in the Anning and Xigu areas.The spatial distribution of the Hui population growth rate between neighborhoods showed a weak positive correlation.Population growth pattern is likely to be more stochastic and unstable.The growth of hotspots range continues to shrink and are locate on the edge of the city.The growth of cold spots are mainly locate in the old city with the scope expanding.There are five blocks remain unchanged.On the basis,the article systematically summarizes the social response to the spatial evolution of the Hui population from four perspectives which inheriting national cultural heritage,enhancing the city inclusive,booming urban economy and building a harmonious society.This article think that with the geopolitical structure evolving from the dwelling around the mosque into the dwelling near the mosque,and the social structure evolving from "intensely segregated" into "relatively integration",and because the difference of religious beliefs,ethnic,c
