西南地区城市土地开发强度时空格局研究

Spatio-Temporal Pattern of Urban Land Development Intensity in Southwest China

摘要: 本文以西南地区33个地级以上城市为研究单元，运用泰尔指数、莫兰指数探究城市土地开发强度的时空格局演变，结论如下：1) 在时序演进上，2006~2020年西南地区城市土地开发强度整体呈增长趋势，城市土地开发强度差异缩小。城市土地开发强度由2.38%增长至4.12%，泰尔指数由0.3873下降到0.3541。2) 在空间格局上，全域角度看，西南地区城市土地开发强度呈现显著的全局空间正相关性，但空间相关状态不稳定。局域角度看，城市土地开发强度较高的城市主要集中在省会城市和其邻近城市，而云南省的保山、临沧和普洱的城市土地开发强度呈现低值集聚现象。

Abstract: This article takes 33 cities at or above the prefecture level in the southwest region as research units, and uses the Thiel index and Moran’s I Index to explore the spatio-temporal pattern evolution of urban land development intensity. The conclusions are as follows: 1) In terms of temporal evolution, the overall urban land development intensity in the southwest region showed an increasing trend from 2006 to 2020, and the difference in urban land development intensity narrowed. The intensity of urban land development increased from 2.38% to 4.12%, and the Theil index decreased from 0.3873 to 0.3541. 2) In terms of spatial pattern, from a global perspective, the urban land development intensity in the southwest region shows a significant global positive spatial correlation, but the spatial correlation state is unstable. From a local perspective, cities with high intensity of urban land development are mainly concentrated in provincial capital cities and their neighboring cities, while the urban land development intensity of Baoshan, Lincang, and Pu’er in Yunnan Province shows a low value agglomeration phenomenon.
