【摘要】：综合交通网络演进产生的时空压缩效应对于中心城市辐射场时空格局演变具有重要影响。在Arc GIS10.0空间分析模块支持下,通过城市综合影响力指数和场强、场能模型对2005,2014年浙江省11个地市的辐射场时空格局演变进行测度研究,并对腹地划分、扩展趋势及偏移度进行分析。研究发现:(1)随着交通网络不断完善和综合实力不断提升,浙江省总体空间场能不断提高,但中心高于外围、干线高于周边以及北部高于南部等区域差异现象明显;(2)以杭州为枢纽的高铁网络成为场能集聚新高地,空间场能呈现以"X"型高铁线为骨架的新型分布格局;(3)杭州、宁波以及金华等地市具有较高腹地偏移度,其腹地超出自身市域并延伸袭夺周边相邻乃至非相邻地市腹地范围;(4)大部分地市腹地与政区范围吻合度较差,少数地市"小马拉大车"现象突出,腹地与政区匹配关系的研究可为浙江省重构城市经济功能区划和指导区域经济一体化发展提供重要参考。
[Abstract]:The space-time compression effect caused by the evolution of integrated traffic network has an important influence on the evolution of space-time pattern of radiation field in central city. Supported by Arc GIS10.0 spatial analysis module, the influence index and field strength of urban comprehensive influence are obtained. The field energy model measures and studies the evolution of space-time pattern of radiation field in 11 cities of Zhejiang Province in 2005 and 2014, and analyzes the division of hinterland, the trend of expansion and the degree of migration. It is found that: 1) with the continuous improvement of traffic network and the improvement of comprehensive strength, The total spatial field energy of Zhejiang Province is increasing, but the center is higher than the periphery, the trunk line is higher than the periphery and the north is higher than the south. The spatial field can present a new distribution pattern with "X" high-speed railway line as the skeleton.) Hangzhou, Ningbo, Jinhua and other cities have high hinterland migration. Its hinterland is beyond its own city area and extends into the surrounding neighboring and even non-adjacent cities hinterland. (4) most of the hinterland of the prefecture and the administrative district are in poor agreement, and the phenomenon of "pony pulling cart" in a few prefectures is prominent. The study of the matching relationship between hinterland and administrative district can provide an important reference for Zhejiang Province to reconstruct urban economic functional zoning and guide the development of regional economic integration.
