摘要:
为探究云南省彝语地名与自然社会因子的关系，采用相关分析、自动线性建模、空间回归等方法进行不同侧面的分析。分析结果如下：1) 从相关分析与回归分析结果来看，各项自然社会因子重要性从大到小依次排列为：彝语地名与铁路距离、高程、彝语地名与道路距离、彝语地名与农用地距离、彝语地名与主要城市距离、彝语地名与水系距离、坡度。2) 从空间回归结果看，地区生产总值、人均GDP、年均温、年降水量、人均受教育年限、文盲率、成人识字率、彝族人口数量与彝语地名数量成负相关。第一产业增加值、第二产业增加值、第三产业增加值、医疗机构床位数、总人口与彝语地名数量成正相关。医疗机构床位数、年降水量通过显著性检验，表明彝语地名数量多的县市区医疗机构床位数相对也多，医疗条件相对较好；彝语地名数量多的县市区降水量相对较少。
Abstract:
In order to explore relationship between natural and social factors and placenames named in Yi nationality language in Yunnan province, the paper used correlation analysis, automatic linear modeling and spatial regression analysis methods to analyze it, then these conclusions could be drawn as follows. 1) From the correlation analysis and regression analysis results, the importance of natural and social factors were arranged in descending order: the distance between placenames named in Yi nationality language and railway, elevation, the distance between placenames and road, the distance between placenames and agricultural land, the distance between placenames and main cities, the distance between placenames and water system, slope. 2) From the spatial regression analysis results, GDP, real GDP per capita, annual mean temperature, annual precipita-tion, education years’ per-capita, illiteracy rate, adult literacy rate and size of Yi population were negatively correlated to the number of placenames named in YI nationality language. The value- added of the primary industry, value-added of secondary industry, value-added of the tertiary in-dustry, number of beds in medical institutions and total population were positively correlated to the number of placenames named in Yi nationality language. And the number of beds in medical institutions and annual precipitation passed the significance test, this indicated the counties and cities that had more placenames named in Yi nationality language had more beds in medical in-stitutions, they had relatively good medical conditions, however, their annual precipitation was relatively little.
