【摘要】：江漢平原地接武漢城市圈和鄂西生態(tài)文化旅游圈,倚靠長江經(jīng)濟(jì)帶,是湖北兩圈一帶戰(zhàn)略的銜接區(qū)域,也是壯腰工程的主體區(qū)域,加快對江漢平原縣域經(jīng)濟(jì)發(fā)展對湖北區(qū)域發(fā)展戰(zhàn)略具有重要意義。運用計量地理方法結(jié)合GIS空間分析方法對江漢平原縣域經(jīng)濟(jì)空間格局進(jìn)行研究,得出以下結(jié)論。(1)運用極差、標(biāo)準(zhǔn)差、加權(quán)變異系數(shù)、相對發(fā)展率、區(qū)位商等方法得出以下結(jié)論：江漢平原縣域人均GDP據(jù)對差異城鄉(xiāng)逐漸擴大的趨勢；同時江漢平原縣域人均GDP相對差異仍然呈現(xiàn)逐年擴大的趨勢。江漢平原縣域經(jīng)濟(jì)發(fā)展速度較高的地區(qū)有當(dāng)陽、枝江、漢川、仙桃市、潛江等地；江漢平原縣域經(jīng)濟(jì)結(jié)構(gòu)在2002-2013年這段時間里有了一定的調(diào)整與優(yōu)化。(2)運用主成分分析法和GIS空間分析法對江漢平原縣域經(jīng)濟(jì)進(jìn)行分析,結(jié)果顯示,江漢平原各縣市綜合經(jīng)濟(jì)總體上呈現(xiàn)北高南低的空間格局。經(jīng)濟(jì)中心由西向東轉(zhuǎn)移,即由荊州區(qū)向仙桃、潛江、天門三個地區(qū)轉(zhuǎn)移。出現(xiàn)北部高于南部,東北高于西北的不均衡空間形態(tài),經(jīng)濟(jì)差距有擴大的趨勢。(3)對江漢平原15個縣市綜合經(jīng)濟(jì)水平測定的基礎(chǔ)上,進(jìn)一步對其進(jìn)行層次聚類分析,綜合2002年、2005年、2009年、2013年所得結(jié)果,進(jìn)行進(jìn)一步綜合歸納,將江漢平原15個縣市經(jīng)濟(jì)發(fā)展分成三種類型,即第一產(chǎn)業(yè)拉動型、第二產(chǎn)業(yè)拉動型、第三產(chǎn)業(yè)拉動型。(4)運用空間自相關(guān)理論對江漢平原縣域人均GDP和綜合經(jīng)濟(jì)水平進(jìn)行分析,江漢平原各縣市人均GDP在空間上的分布并非完全處于隨機狀態(tài),而是表現(xiàn)出一定的空間積聚,即人均GDP較高的地市具有相互積聚的空間特征。2002年江漢平原各縣市綜合經(jīng)濟(jì)Moran's I指數(shù)為負(fù)數(shù),說明2002、2005年江漢平原各縣市綜合經(jīng)濟(jì)空間相關(guān)性不顯著,具有負(fù)相關(guān)性,2009、2013年兩年江漢平原各縣市綜合經(jīng)濟(jì)Moran's I指數(shù)為正數(shù),說明這兩年江漢平原各縣市綜合經(jīng)濟(jì)空間相關(guān)性顯著。2002-2013年,江漢平原各縣市綜合經(jīng)濟(jì)Moran's I指數(shù)不斷增長,說明江漢平原各縣市綜合經(jīng)濟(jì)空間正相關(guān)不斷增強。
[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.
