本文利用社交网络分析法和GIS可视化,在地理学视角下,对微博中"山东毒疫苗事件"信息传播路径进行定量分析.研究发现:①空间结构与社会经济具有相对一致性,表现为网络中节点的出入度与社会城市发展具有指向性,在个别中心城市间(北京、 广东、 上海)有所区别;②舆论微博传播具有地域性,不同的地域都形成中心节点城市,这些城市主导着周边乃至全国范围内的舆论方向;③相同时间段内的舆论信息传播路径数量在空间分布上呈现出不对称性,东部地区要比中西部地区密集.%The dissemination of internet-based information changed the previous pattern of geography, while micro-blog has formed an important platform for exchanging information. Using the method of social network analysis ( SNA) and GIS visualization, this paper tries to analyze the path of information transmission in micro-blog from the perspective of geography. Eventually the results show as fol-lows.①The spatial structure and the social economy are relatively consistent. The number of in-out degree in network is consistent with the development of the economic level, while situations of dissemination are different in certain central cities.②The space of network information has the geographical features. Those cities as center-nodes dominate the direction of public opinion in the surrounding areas, even nationwide direction.③In network, the dissemination number of public opinion is regional during the same time frame.
