西海固回族聚居区空间分布研究对该地区制定经济发展战略、优化居民点空间布局和编制生态移民规划具有重要意义。文中借助ArcGIS的空间分析和统计方法分析西海固回族聚居区空间分布特征及影响因素。结果表明:西海固回族聚居区空间分布整体呈现“大分散、小集中”的特征,分布密度呈现北、西、南三面高,东部低的“扇形”特征。另外,受坡度、海拔、河流水系和道路交通的影响较大,具有强烈的低坡度、低海拔的区位取向以及明显的河流、道路趋向性分布特点。影响回族聚居区空间分布的因素有:历史演进、人地关系演变、宗教文化和政策制度。
The study on the spatial distribution of the Xihu-Gui area is of great significance to formulating the economic development strategy, optimizing the spatial distribution of settlements and planning the eco-immigration. In this paper, spatial analysis and statistical methods of ArcGIS are used to analyze the spatial distribution characteristics and influencing factors of the Huihai inhabited by the West Sea. The results show that the spatial distribution of the Hui nationality in Xihaigu area shows the characteristics of “large dispersal and small concentration” as a whole. The distribution density shows the characteristics of “fan-shaped” with high elevation in the north, west and south and low in the east. In addition, it is greatly affected by slope, altitude, river system and road traffic, with strong low gradient, low altitude location orientation and obvious river and road trend distribution. The factors influencing the spatial distribution of the Hui people are: historical evolution, the evolution of man-land relationship, religious culture and policy system.
