摘要
选取贵州省县域人口、国内生产总值（GDP）等数据,基于重心变化和探索性数据空间分析等方法,分析贵州省2006～2014年人口与经济分布格局时空演变特征。结果表明：1）贵州省人口分布重心从几何重心的西北部逐渐向西部迁移,在2009年迁移距离减小,分布重心的位置逐步稳定;GDP的重心分布于贵州省几何重心的西部,位置变化较小;第二、三产业分布重心与GDP分布重心较近;第一产业重心不断向人口分布重心靠近。2）贵州省经济空间分布处于低水平均衡发展阶段,县域人口、GDP和第三产业Global Moran＇s I指数均未通过显著性水平检验,仅第一产业和第二产业通过了该检验,要素集聚水平低。3）贵州省县域人口和GDP变化热点区呈现集聚特征,进一步向黔中地区集聚。4）在推进工业化、城市化过程中,贵州省要进一步提高城市首位度,提升工业、服务业发展水平,以产业发展吸引人口集聚。
Based on the method of the center of gravity change and exploratory spatial data analysis, we applied county population, GDP, etc. to explore the spatio-temporal evolution of the regional popu- lation and economic of Guizhou province from 2006 to 2014. The results indicated that： 1 ） The gravity center of the population distribution in Guizhou province has moved from the northwest to the west, and the migration distance was smaller, gradually became stable in 2009 ; the gravity center of GDP located in the west which became the geometric center and changed little ; the distribution center of the second- ary and tertiary industries was close to the GDP center; the gravity center of the primary industry was continuously close to the gravity center of the population. 2） The spatial distribution of the economy in Guizhou province was at a low level balance development stage, the Global Moran＇s I index of the coun- ty＇s population, economy and the tertiary industry did not pass the significance level test, only the pri- mary industry and the second industry changes of the population and GDP in passed the test, the factor agglomeration level was low. 3 ）The the hot spots of the county in Guizhou province presented the characteristics of agglomeration, and growth was further concentrated in central Guizhou. 4） In theprocess of promoting industrialization and urbanization, we must improve the primary index of Guizhou,improve the level of industry and service industry in Guiyang, use industrial development to attract population agglomeration.
