摘要：交通网络演变深刻影响着中心城市腹地范围的变化.选取1999年、2005年、2011年、2018年4个年份作为时间断面,在扬子江城市群社会经济数据和交通地理数据的支持下,利用改进场强模型并结合GIS方法,研究扬子江城市群腹地范围演变,并提出扬子江城市群协同发展的思路.研究表明:(1)扬子江城市群可达性有明显改善,高等级公路大发展时期可达性相对较差,平均可达性大于1.5 h的区域面积占比为42.4%;到高铁稳定发展时期,扬子江城市群平均可达性为1.5~2 h的区域面积占比仅为0.5%,1.5 h通勤圈已基本形成.(2)扬子江城市群腹地范围演变表现为苏州的腹地较大,腹地面积占比基本在50%以上;南京腹地面积占比基本在20%左右;南通腹地面积占比基本在10%左右;无锡、常州、镇江、泰州、扬州的腹地相对较小.(3)扬子江城市群协同发展设想:打造增长极,引领区域一体化发展;优化苏中可达性,打造1 h通勤圈;加速跨江融合,缩小区域差距.
The evolution of the traffic network has a significant influence on the variety of central city’s hinterland.The four years 1999,2005,2011 and 2018,are selected as time cross-sections.With the support of the socio-economic database and the traffic geographic database of the Yangtze River City Group,we apply field-strength model and GIS to study the evolution of the urban hinterland of the Yangtze River City Group.At the same time,the ideas of coordinated development of Yangtze River City Group are analyzed.The results show that:(1)The accessibility of Yangtze River City Group has been significantly improved,and the accessibility is relatively poor in the large-scale development period of high-grade highway,and the area with average accessibility over 1.5 h accounts for 42.4%.In the stable development period of high-speed rail,the area with average accessibility of 1.5-2 h is only 0.5%,and the 1.5 h commuter circle has been basically formed.(2)The evolution of the urban hinterland of the Yangtze River City Group shows that Suzhou has the biggest urban hinterland,and the area accounts for more than 50%.The urban hinterland of Nanjing is about 20%,that of Nantong is about10%,and that of Wuxi,Changzhou,Zhenjiang,Taizhou and Yangzhou are relatively small.(3)The ideas of coordinated development of Yangtze River City Group are put forward:creating growth pole and leading the development of regional integration;optimizing the accessibility of middle Jiangsu and creating a 1-hour commuter circle;accelerating the integration of south Jiangsu and middle Jiangsu,and narrowing the regional development gap.
