摘要:
社会感知技术是研究重特大地震事件中灾区民众行为反应时空特征的一种有效手段。采用情感词典和规则相结合的方法,以2013年四川芦山7.0级和2017年九寨沟7.0级地震为例,用震后24 h微博数据分析了地震灾区民众微博数量特征、情感极性特征、情绪时间序列特征、情绪反应空间分布特征。研究结果表明:芦山地震灾区民众负面情绪大于正面情绪,而九寨沟地震后民众正面情绪大于负面情绪,微博活跃数量程度与人口密度、生命线破坏程度、震中距离和烈度密切相关,微博活跃数量呈现空间分布不均衡特征。分析认为,2次地震后,灾区民众情感行为反应差异主要与灾区人口密度、房屋抗震性能、当地民众防震减灾意识、地震知识了解程度等密切相关。
Abstract:
Social perception technology is an effective means to study the temporal and spatial characteristics of people's behavior response in earthquake-strichen areas. Taking Lushan M7.0 earthquake in 2013 and Jiuzhaigou M7.0 earthquake in 2017 in Sichuan as examples,we obtain the 24 hours Weibo data after the earthquake by emotional dictionary and rules,and analyze the quantitative characteristics,the emotional polarity characteristics,temporal and spatial distribution characteristics of emotional response in the earthquake-stricken area. The results show that the negative emotions of the people in Lushan earthquake-stricken area are greater than the positive ones,and the positive ones in Jiuzhaigou earthquake are greater than the negative ones. The degree of microblog activity is closely related to population density,lifeline damage,epicenter distance and intensity and the spatial distribution of it is unbalanced. The main reasons for the difference of people's emotional and behavioral responses in the two earthquake-stricken areas are closely related to the population density,the seismic performance of buildings,the awareness of earthquake prevention and disaster reduction of local people,and the awareness of earthquake science popularization.
