我国西南地区彝族人口空间分布研究

Research on the Spatial Distribution of Yi People in Southwest China

摘要: 本文主要运用中位数中心、平均中心、中心要素、方向分布、标准距离、空间自相关和热点分析等方法，对我国西南地区彝族人口空间分布进行调查和计算分析。结果表明我国西南地区彝族人口中心要素位于玉溪市，中位数中心和平均中心皆位于昆明市；西南地区的彝族人口具有空间正相关性，与空间聚集度成正比；该地区的彝族人口空间分布既不符合水平分布，也不符合竖直分布，但是我国西南地区的彝族人口在云南省区域内有一个高值的空间聚类，即该区域对彝族人口分布有着很高的置信度，而在重庆市，以及贵州省、四川省的极少区域存在一个低值的空间聚类，即该区域的彝族人口分布较少。

Abstract: In this paper, the methods of median center, average center, central element, direction distribu-tion, standard distance, spatial autocorrelation and hot spot analysis are used to investigate and calculate the spatial distribution of Yi population in Southwest China. The results show that the central elements of Yi population in Southwest China are located in Yuxi City, the median center and average center are both located in Kunming City, and the Yi population in Southwest China has a positive spatial correlation, which is proportional to the degree of spatial aggregation. The spatial distribution of Yi population in this area is neither consistent with horizontal distribution nor vertical distribution, but the Yi population in southwest China has a high value spatial cluster in Yunnan province. That is to say, there is a high degree of confidence in the distribution of Yi population in this region, but in Chongqing and Guizhou Province, and very few areas in Sichuan Province, there is a low value spatial cluster in, that is, the distribution of Yi population in this region is relatively small.
