Comparison of realistic geo-space and virtual cyberspace in China
Wu Shi · 2008
The aim of this study is to compare and analyze Chinese traditional geo-space and cyberspace.Some characteristics of the two spaces are compared taking China as an example,including connection frequency in provinces,connection types basing on the main network and connection speed between nodes of cities.Some basic types and characteristics of the two spaces are obtained using the method of principle component,the characteristics of connection types are concluded using the method of network analysis,and by analyzing the program exam data from five exam spots in China using the method of distance attenuation of servers the comparison analysis and rule cognition of connection speed are made.The results show: 1) In connection consequence,strong connection area and weak one are corresponding in the rough and the weak connection area surrounds the strong one.Connection consequence of cyberspace is not degression because of far away from the center,which is different from geo-space.2) In connection type,city centripetalism is obvious but center spots are different.The hierarchy of node is relatively accord but the barycenter of main network is not accord.The distribution types of network line include easy and complex ones.The distribution type of flow include one-direction and multi-direction,stability and instability,and continuity and discontinuity.And 3) In connection speed,relation spots of the two spaces appear scatter distributing,but aggregation is still exist in scatter distributing while out the aggregation area,geo-space distance and cyberspace distance is isochronous.Cyberspace distance has the rule of instantaneous and geo-space has the rule of distance-depending.
