云南省人口与经济区域结构特征研究

The Research of Characteristics of Regional Structure of Population and Economy in Yunnan

基于云南省2000、2005、2010、2015年的人口与经济指标和云南125个县(市)的空间矢量数据,借助空间分析技术(GeoDa和ArcGIS),运用Moran I指数、Moran I散点图及LISA集聚图,揭示云南各县(市)人口与经济空间分布形态、集聚特征以及时空演变规律。结果表明:云南各县(市)人口与经济的空间分布具有较明显的空间自相关性,即存在较强的空间集聚特征。其中,人口空间格局的演变总体上变化不大,滇中地区、滇东北部分地区为高-高型,滇西北、滇西南地区为低-低型;经济空间格局与人口分布大致吻合。基于人口、经济的双变量分析表明,人口与经济发展存在明显的地域不均衡性,最终以人口、经济发展的协调程度把云南省划分为高-高型、低-低型、低-高型、高-低型4类,并提出了不同类型区域人口—经济结构形态的优化对策。

Based on the indicators of population and economic in2000,2005,2010,2015,and spatial vector data of125counties(cities)in Yunnan Province,With the Spatial analysis techniques(GeoDa and ArcGIS),the Moran I index,Moran I scatter plot and LISA agglomeration map are used to reveal The spatial distribution pattern of population and economy in Yunnan counties(cities),and the temporal and spatial change.The results show that the spatial distribution of population and economy in Yunnan counties has obvious spatial autocorrelation,that is,there is strong spatial clustering characteristics.Among them,the evolution of population-spatial pattern is not changed in the middle of Yunnan,and the northeastern part of Yunnan is high-high,northwest Yunnan and southwest Yunnan is low-low.The economic-spatial pattern is in good agreement with the population distribution.Based on the population and economic bivariate analysis,there are obvious regional imbalances in population and economic development.Finally,Yunnan Province is divided into high-high type,low-low type,low-high type,High-low type by using the coordination degree of population and economic development,and put forward the different types of regional population,economic structure of the optimization strategy.
