【摘要】：江汉平原地接武汉城市圈和鄂西生态文化旅游圈,倚靠长江经济带,是湖北两圈一带战略的衔接区域,也是壮腰工程的主体区域,加快对江汉平原县域经济发展对湖北区域发展战略具有重要意义。运用计量地理方法结合GIS空间分析方法对江汉平原县域经济空间格局进行研究,得出以下结论。(1)运用极差、标准差、加权变异系数、相对发展率、区位商等方法得出以下结论：江汉平原县域人均GDP据对差异城乡逐渐扩大的趋势；同时江汉平原县域人均GDP相对差异仍然呈现逐年扩大的趋势。江汉平原县域经济发展速度较高的地区有当阳、枝江、汉川、仙桃市、潜江等地；江汉平原县域经济结构在2002-2013年这段时间里有了一定的调整与优化。(2)运用主成分分析法和GIS空间分析法对江汉平原县域经济进行分析,结果显示,江汉平原各县市综合经济总体上呈现北高南低的空间格局。经济中心由西向东转移,即由荆州区向仙桃、潜江、天门三个地区转移。出现北部高于南部,东北高于西北的不均衡空间形态,经济差距有扩大的趋势。(3)对江汉平原15个县市综合经济水平测定的基础上,进一步对其进行层次聚类分析,综合2002年、2005年、2009年、2013年所得结果,进行进一步综合归纳,将江汉平原15个县市经济发展分成三种类型,即第一产业拉动型、第二产业拉动型、第三产业拉动型。(4)运用空间自相关理论对江汉平原县域人均GDP和综合经济水平进行分析,江汉平原各县市人均GDP在空间上的分布并非完全处于随机状态,而是表现出一定的空间积聚,即人均GDP较高的地市具有相互积聚的空间特征。2002年江汉平原各县市综合经济Moran's I指数为负数,说明2002、2005年江汉平原各县市综合经济空间相关性不显著,具有负相关性,2009、2013年两年江汉平原各县市综合经济Moran's I指数为正数,说明这两年江汉平原各县市综合经济空间相关性显著。2002-2013年,江汉平原各县市综合经济Moran's I指数不断增长,说明江汉平原各县市综合经济空间正相关不断增强。
[Abstract]:The Jianghan Plain is connected with Wuhan City Circle and Western Hubei Eco-cultural Tourism Circle, relying on the Yangtze River Economic Belt, which is the strategic link area of Hubei's two circles, and is also the main area of the Zhuangyao Project. Speeding up the development of county economy in Jianghan Plain is of great significance to Hubei's regional development strategy. This paper studies the spatial pattern of county economy in Jianghan Plain by using the method of econometric geography and GIS spatial analysis, and draws the following conclusions: (1) using extreme deviation, standard deviation, weighted coefficient of variation, relative development rate, Location quotient and other methods draw the following conclusions: the average GDP per capita in Jianghan Plain is gradually expanding according to the difference between urban and rural areas, and the relative difference of per capita GDP in Jianghan Plain is still increasing year by year. Jianghan Plain county economic development rate is high in Dangyang, Zhijiang, Hanchuan, Xiantao, Qianjiang and other places; The county economic structure of Jianghan Plain has been adjusted and optimized in the period of 2002-2013. (2) the principal component analysis and GIS spatial analysis are used to analyze the county economy in Jianghan Plain. Jianghan Plain counties and cities on the whole presented a comprehensive economic north high south low spatial pattern. Economic center from west to east, namely from Jingzhou District to Xiantao, Qianjiang, Tianmen three areas transfer. The disequilibrium spatial form of the north is higher than the south and the northeast is higher than the northwest. (3) on the basis of measuring the comprehensive economic level of 15 counties and cities in Jianghan Plain, the hierarchical cluster analysis is carried out. According to the results obtained in 2002, 2005, 2009 and 2013, the economic development of 15 counties and cities in Jianghan Plain is divided into three types, namely, the first industry-led type, the second-industry-driven type, and the second-industry-driven type. (4) the spatial autocorrelation theory is used to analyze the average per capita GDP and comprehensive economic level in Jianghan Plain. The distribution of GDP per capita in Jianghan Plain is not completely random. In 2002, the Moran's I index of the counties and cities in Jianghan Plain was negative. The results show that the spatial correlation of comprehensive economy in Jianghan Plain was not significant in 2002,2009.In 2013, the Moran's I index of counties and cities in Jianghan Plain was positive. The results show that the spatial correlation of comprehensive economy between counties and cities in Jianghan Plain is significant. The Moran's I index of counties and cities in Jianghan Plain has been increasing continuously in the past two years, which indicates that the positive correlation of comprehensive economic space between counties and cities in Jianghan Plain is increasing.
