The Development Strategy Of Urban Space Integration In Metropolitan Area

Regional integration is one of the most dynamic economic phenomena and an important mode of modern regional development.Metropolitan area is in the globalization,informatization and traffic system formed under the influence of geographical form,its emergence has changed the city’s geographic space and scale,this study choose the Xianyang as the research object,which in the Xi’an international metropolis core component.Based on the literature review,night lighting remote sensing data in 1992-2019,the land use data from 1980-2015 and point of interest(POI)data,the Xianyang in blend in Xi ’an international metropolis city in the process of outer space and urban internal space changes process were analyzed,the main conclusions were following:(1)From 1985 to 2015,urban land use in Xi ’an and Xianyang increased significantly from1987(P<0.05).In Xi ’an and Xianyang administrative regions,from 1980 to 2015,woodland area and urban residential area showed an increasing trend,wetland water area and desert area remained basically unchanged,and grassland area,irrigated farmland area and dry land area showed a decreasing trend.(2)From 1992 to 2013,the change of night lights in Xi’an and Xianyang administrative regions showed an increasing trend.During the 1992-2013,the center of gravity in the builtup area of Xi’an first moved to the southwest and then to the northwest.From 1992 to 1997,the moving speed was 199.7 meters per year,and then decreased to 117.9 meters per year from 1998 to 2003.After 2000,the moving speed of the center of gravity in the built-up area accelerated,reaching 948 meters per year from 2010 to 2013.And built up area of Xianyang center of gravity in 1992-2013,first to southeast direction,to the northeast direction,after the movement speed to 187 m a year between 1992 and 1997,and reached the maximum in 1998-2003(1350 m)a year,and then down to 2004-2009 of 300.5 m a year,in 2010,built up area center of gravity,movement speed reached 889 meters per year in 2010-2013.On the whole,the center of gravity in Xianyang built-up area tended to move to the northeast from 1992 to 2013.(3)The POI data were used and kernel density analysis showed that different types of POI in Xianyang city had basically the same spatial distribution,with the old urban area formed by Leyu Road and Renmin Road at the junction of Qindu District and Weicheng District as the main center,and the Southern area across Weihe River gradually connected with the old urban center to form a larger main urban center.Xingping city,Jinggan Street jingyang County and Liquan County Chengguan town as the sub-center of the city...
