【摘要】 基于网络信息,以学生群体对汶川8.0级地震响应为研究对象,通过对搜集到的复杂网络信息的分类和分级,刻画出非灾区学生群体的灾害响应能力,探讨了学生灾后响应主要类型、强度的空间分异及灾后响应的驱动力。结果表明:①学生灾后响应的主要类型是学生自发捐款、中小学异地复课等;②造成学生灾后响应空间差异的主要因素不是交通条件,而是空间距离导致心理疏离;③学生灾后响应的驱动力随时间的变化特征不同,其中满足自我强化需要的响应速度快但持续性较低,而满足灾源地的需要的响应速度慢但持续性高。更多还原

【Abstract】 Based on web-based information,response of students to the M8.0 Wenchuan earthquake in May 2008 is explored,including the spatial differentiations of response types,its intensity,and driving forces.The major objective is to evaluate the differences of response capacity of students.The results show that:① students’ voluntary donation and resumption of classes outside the disaster affected areas are two main kinds of post-disaster response;② the main factor that determines the spatial differentiations of response is not the traffic condition,but the psychological alienation due to the long distance;③ the driving forces vary over time,in which the one to meet the need of self-reinforce has a high speed but lower sustainability,while the one to meet the needs of disaster affected areas has a low speed but high sustainability.更多还原
