改革开放以来济-青双核结构的空间关系演变

济—青双核结构是山东省典型的双核结构。明确改革开放以来济—青双核结构的空间关系演变,是整合济南、青岛功能的基础。改革开放的前十几年,济—青双核结构的空间关系以对抗性竞争为主。通过主成分分析,借助ArcGIS3．3软件,得出近年来在济南与青岛的竞争中,青岛的腹地范围西扩明显;从分形角度,度量出近年来济南与青岛引力不断增强,空间关系向合作性竞争转变。影响济—青双核结构空间关系演变的因素是政策因素,规模因素,资源特性因素,生产方式因素,网络载体因素。

The Evolution of the Relation of Ji-Qing Dual-Core Structure Since Reform and Opening Up

The Dual-Core Structure of Jinan and Qingdao is very typical in Shandong province. It is important to have a clear spatial relationship between Jinan and Qingdao, for it is the basis to integrate the function of the two cities. The main character of the spatial relationship between Jinan and Qingdao is confrontational competitive from 1978 to 1992. Using principal component analysis method together with the software of ArcGIS ,it has drawn a conclusion that Qingdao has been expanding the scope to western Shandong in recent years;From the fractal point of view, it has measured out the two city ever-increasing gravity trend in recent years,which reflects the space relations between the two cities has changed from competition to cooperation. The factors of impacting on the evolution of spatial relations is policy factor, scale factor, resource characteristics factor,production methods factor and network carrier factor.
