云南省土地经济密度空间格局演变及其影响因素

Spatial pattern evolution and influencing factors of land economic density in Yunnan Province

以云南省16个地州市为例,运用了地理探测器、泰尔指数、变差系数、相对发展率、空间自相关分析、热点分析等方法探究了2011—2020年云南省土地经济密度的空间格局演变规律及其影响因素。结果表明,2011—2020年云南省土地经济密度呈中部高两边低、南部高北部低的格局,但是随着时间的变化其差异在不断缩小;Moran’s I指数先下降再稳步上升,且均为正值,表明土地经济密度存在空间集聚状态;空间集聚特征明显,热点区主要集中在滇中城市群;地均社会零售商品总额、人均GDP等经济类驱动因子对云南省土地经济密度的解释力较大,且任何两因子的交互解释力优于单个因子的解释力。

Taking 16 prefectures and cities in Yunnan Province as an example,the spatial pattern evolution and influencing factors of land economic density in Yunnan Province from 2011 to 2020 were explored by using geographical detectors,Theil index,variation coefficient,relative development rate,spatial auto-correlation analysis and hot spot analysis.The results showed that,from 2011 to 2020,the land economic density of Yunnan Province showed a pattern of“high in the middle and low on both sides,high in the south and low in the north”,but the difference was narrowing with time.Moran’s I index value decreased first and then increased steadily,and all were positive,indicating that there was a spatial agglomeration of land economic density.The spatial agglomeration characteris⁃tics were obvious,and the hot spots were mainly concentrated in the urban agglomeration of central Yunnan.The economic driving fac⁃tors such as the total retail sales of local consumer goods and per capita GDP had great explanatory power on the land economic density in Yunnan Province,and the explanatory power of any two factors interacting with each other was better than that of a single factor.
