ICTs(信息与通信技术)的迅速发展促使目前信息社会特征日渐清晰,其特征的研究受到了越来越多的地理学关注,特别是在信息网络及其空间范围、结构等领域。文章在计算了信息网络节点城市的信息吸引力指数基础上,利用断裂点公式计算了部分城市的信息辐射面积,运用SPSS软件进行了信息指数与信息辐射面积的函数模拟,确定了省会城市信息节点辐射空间,并探讨了其地区差异。
The ICTs (information and the correspondence technique) quick development urge currently social characteristic of information gradually clear, the research of its characteristic was subjected to more and more geography concerns. Especially in the information network and its space scope, structure realms. This text makes use of to split some formula to compute the information radiation area of parts of cities in computing the foundation of the information attraction index number of the information network node city, making use of the SPSS software to carry on the information index number and informations to radiate the function emulation of the area, applying to really settle in the provincial capital city information node radiation space and space discrepancy.
