Tempo-spatial compression effect created by integrated transport network evolution has significant effects on the spatial field evolution of prefecture-level cities.With the help of spatial analysis module of ArcGIS 10.0,using integrated urban influential index and spatial field models,the paper studied spatial field evolution of eleven cities of Zhejiang Province from 2005 to 2014 as well as dividing hinterland,extending trends analysis and deviation range analysis.The results show that:① Along with transport links improving and city's comprehensive strength rising,overall spatial field of Zhejiang Province is improving continually.However,spatial field of central area is higher than the periphery's,major transport lines higher than the surroundings,and northern area higher than southern area.② High-speed rail networks centered by Hangzhou became new spatial field agglomeration highland,and spatial field render new distribution pattern characterized by X type of high-speed railway lines;③ Some cities,such as Hangzhou,Ningbo and Jinhua and so on,have higher hinterland deviation range.Hinterland range of those cities extended beyond district area and even across to another ones;④ Hinterland coincided poorly with the administrative division,and the phenomenon of "small horse with a big cart" is prominent.Hinterland can be regarded important references for restructuring economic functional district and directing regional economic integration development of Zhejiang Province.%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ArcGIS10.0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.
