In the background of integrative economy all over world , forming and developing of global city is increasing , especially emergence new spatial city structure such as city cluster , metropolitan area , metropolis taenia , metropolis stretch and so on , its play a important role of cosmopolitan note city in the system of global city network , and more and more dominate global economical life line , in the meantime exceed national entity on the spatial power 在全球经济一体化的背景下，世界城市的形成和发展很快，尤其是出现了像城市群、大都市区、大都市带、都市连绵带等新的城市空间组织形式，这些新的城市空间组织形式，在全球城市网络体系中扮演着世界性节点城市的角色，它们越来越控制和主宰着全球的经济命脉，越来越在空间权力上超越国家的实体。
The notion of synergy , which makes the whole network of cities more than the sum of its parts , will be discussed in the light of a fuzzy strategic concept that qualifies rhineruhr as a “ metropolitan region ” constituting a critical mass for international competitiveness on the one hand , but hardly any steps to implement this option on the other 协同，意味着使整个城市网络的功效大于其各部分的相加，我们将在一个模糊战略概念中讨论这一问题，该战略一方面把莱茵鲁尔作为一个构成关键国际竞争力的“大都市区” ，而另一方面，对这一战略却少有实施。
But , in the backdrop of westward opening up and globosity economy , development problem of lan zhou " city on how to be in harmony with city and urban around it henceforth , how to lead to development to city and urban around lanzhou according to a more optimizing structure of city and urban , how to become a note city in the network of global city for dissolving a system of global city , turn into a deserving broody question 但是，在经济全球化、西部大开发的背景下，兰州市今后如何与周边城镇协调发展，如何以一种更优化的城镇空间布局，与周边城镇协调发展。如何成为世界城市网络中的一个节点，来溶入全球城市体系，成为一个值得思考的问题。
An exclusively mathematical approach is proposed to address the scale - free property of self ? ? organized networks of cities . defining a spatial correlation function based on the triangular lattice model of cities stemming from central place networks , a scaling relationship is established between yardstick 以河南省为研究区，对城市空间关联进行了实证分析，发现在双对数坐标图上存在明确的无标度区，从而在揭示自组织城市网络内在复杂规律的同时，证实了上述方法刻画无标度城市网络的有效性。

The result indicates that in the early days of informatization , the traffic has been increasing while the soaring of communication though it ' s very slowly , which shows that communication hasn ' t been replaced ; the degree of polarization has increased and as people being inclined to large cities ; so the degree will continue augmenting ; from people ' s recognition of information and traffic , we can see that region still plays an important roll in the city network ' s formation 结果表明，处在信息化发展初期，苏锡常地区在通讯快速发展的同时，交通量尽管增长较慢，但一直稳定增长，并没有被通讯所替代；苏锡常地区极化程度增大，而且由于人们倾向于去大城市工作和生活，所以该地区极化程度将会进一步加强；人们对信息和交通的重视，反映出区位在人们出行乃至整个城市网络的形成中仍然发挥着重要的作用。
