摘　　要：基于中心地和网络城市理论,利用潜力模型对省级国土经济空间结构进行识别。该模型以百度地图服务为基础,建立时间可达性分析模块,提取网络城市节点之间的时间距离;以GDP等指标作为网络城市节点经济实力的综合性度量,并利用双对数Pareto交通流模型建立各中心节点影响力势能场衰减模型。以中部地区湖南省为案例,分析了网络城市组织下的国土空间经济结构。结果表明,湖南省当前呈现出多中心组团模式,整体格局表现为单中心圈层式结构,长株潭城市群是整个国土经济空间的增长极;交通网络带动的经济势能场对传统"点-轴"结构认知具有重要影响。国土经济空间结构识别对湖南省国土规划关于经济空间布局具有重要的参考作用。A potential model is applied to recognize the provincial land economy structure according to the theories of central place and network cities.Based on the Baidu service map,the potential model builds the tool to retrieve the time distance among cities.GDP and some other indices are used to measure the economic effect for different central place.Furthermore,a Pareto model is used to represent the potential attenuation of economy among different urban areas.Hunan province,which is located in the central part of China,is taken as a case study area.The results indicate that the current economic zones of Hunan Province present obvious single-center structure,and the metropolitan area of Changsha-Zhuzhou-Xiangtan is the core of the whole territorial space.In addition,traffic network is an important factor which has influenced the distribution of economic zones.The economic zones under the background of network cities can help the planners to allocate economic activities more reasonably for territorial spatial planning.
