【摘要】：以甘肅省縣域人均GDP為測度指標(biāo),運(yùn)用變異系數(shù)、錫爾系數(shù)和空間自相關(guān)等方法,結(jié)合Arc GIS 10.2及Geo DA軟件對甘肅省2001~2013年縣域經(jīng)濟(jì)的空間差異及演變過程進(jìn)行研究。結(jié)果表明,在時(shí)間上甘肅縣域經(jīng)濟(jì)的差異在逐年增大,2011年后呈現(xiàn)急劇增大的趨勢;在空間上縣域經(jīng)濟(jì)總體有顯著的聚集態(tài)勢,局部空間分析發(fā)現(xiàn),甘肅省縣域經(jīng)濟(jì)兩極分化明顯,河西地區(qū)經(jīng)濟(jì)發(fā)展水平較高,隴中和隴南的大部分縣域經(jīng)濟(jì)發(fā)展水平較低;從分解分析來看,分區(qū)內(nèi)部差異略大于分區(qū)之間差異,區(qū)域內(nèi)部差異是構(gòu)成差異的主要因素。
[Abstract]:Taking the per capita GDP of Gansu county as the measure index, using the methods of variation coefficient, Sier coefficient and spatial autocorrelation, combining with Arc GIS 10.2 and Geo DA software, this paper studies the spatial difference and evolution process of county economy in Gansu province from 2001 to 2013. The results show that the difference of county economy in Gansu is increasing year by year, and the trend is increasing sharply after 2011. On the whole, the county economy has a significant aggregation situation in space. Local spatial analysis shows that the county economy in Gansu Province is polarized obviously, the level of economic development in Hexi region is relatively high, and the level of economic development in most counties in Longzhong and Longnan is relatively low. From the analysis of decomposition, the difference within the region is a little larger than the difference between the regions, and the difference within the region is the main factor of the difference.
