The Effects of the Traffic Network Evolution on the Hinterland of Central Cities——A Case of Jiangxi Province
以江西省为例，利用时间距离和场强模型分析1994、2002、2010、2020年交通网络演化对中心城市腹地的影响，发现交通优化带来时空压缩效应，腹地受自身及其他中心城市交通网络影响，且影响呈现多样化特征。
The evolution of the traffic network has a significant influence on the variety of central city’s hinterland.Select 1994,2002,2010,2020,four years as time cross-sections.With the support of the socio-economic database and the traffic geographic database of Jiangxi Province,we apply time-distance and field-strength model to divide the Jiangxi’s hinterland of central cities.At the same time,the evolution of the time-based area of central cities and the field-strength hinterland are analyzed out.Some conclusions have been put forward:(1)The optimization of traffic network can bring significant time-space compression effect to hinterland of central cities.(2)The hinterland of central cities is affected by the traffic network of itself and other central cities.(3)The effects of the traffic network evolution on the hinterland of central cities show a variety of features obviously.
