2008年的5·12汶川地震作为我国建国以来破坏性最大、波及范围最广的一次特大地震，成为全国人民乃至海外华侨难以抹去的深刻记忆。对于没有亲身经历和无法经历“过去”的人而言，共享的“过去”大多来自大众媒介对“历史上的今天”的书写。那么，作为大众集体记忆重要建构者的媒介，又是如何通过“纪念性报道”来保存和再现共同记忆的呢？ 借助汶川地震十年这一契机，本研究引入集体记忆的理论视角，以2009年至2018年这十年间汶川地震的周年祭报道为例，选取具有党报及全国级性质的《人民日报》、党报及地方级性质的《四川日报》、都市报及全国级性质的《新京报》、都市报及地方级性质的《华西都市报》作为研究对象，聚焦三大问题的探讨：以这四大报纸为代表的纸媒是如何通过纪念报道建构大众对该事件的集体记忆？不同性质、地域的纸媒通过纪念报道构建的集体记忆又有什么差异？媒介如此建构背后的意义何在？ 针对这三大研究问题，本文通过汶川地震十年间集体记忆的纪念报道呈现、汶川地震十年间集体记忆的媒介建构策略、汶川地震集体记忆的建构意义这三个维度进行了详细论述。研究发现，汶川地震十年间集体记忆的纪念报道呈现主要基于报道数量、报道体裁、报道主题、信息来源、报道倾向以及报道类型这六个维度，而且不同性质、地域的纸媒通过纪念报道构建的汶川地震集体记忆存在差异。汶川地震十年间集体记忆的媒介建构策略主要包括内容层面与形式层面两大维度，即在内容层面上对社会事实、集体表征、集体意义展开选择性建构，在形式层面上借助纪念仪式的进行周期性强调与重复。汶川地震集体记忆的建构意义表现为认同与想象共同体的维护。以汶川地震这一震惊海内外的大事件为契机，刺激、唤醒并强化大众关于“中国”“中华民族”这一想象共同体的认知，从而增强国民乃至海外华侨对于中国、中华民族的认同。

As the most destructive and widespread earthquake since the foundation of China, the 5·12 Wenchuan Earthquake in 2008 has become a profound memory that Chinese at home and abroad can hardly erase. For those who have no personal experience and cannot experience the "past"，the shared “past” mostly comes from the writing of “history today” of mass media. As an important constructor of collective memory, how do media preserve and reproduce the common memories through "commemorative reports"? Due to the 10th anniversary of the Wenchuan earthquake, this study introduces the theoretical perspective of collective memory and take the anniversary report of the Wenchuan earthquake from 2009 to 2018 as examples. By selecting People's Daily (party newspaper and central level), Sichuan Daily (party newspaper and local-level ), West China City Daily(metropolis daily and local-level) and Beijing News (metropolis daily and central level)as the research object, this study focuses on three major issues: How do the paper media represented by these four major newspapers construct a collective memory of the incident by commemorating the report? What is the difference between the collective memory constructed by commemorative reports of paper media of different natures and regions? What is the significance behind the media's construction? For these three major research questions, this article will be discussed in detail through these three dimensions: the commemorative report on the collective memory of the "10th anniversary of the Wenchuan earthquake", media construction strategy of collective memory of the "10th anniversary of the Wenchuan Earthquake" and the construction significance of the collective memory of the Wenchuan Earthquake. The study found that the commemorative report of the collective memory of the "10th Anniversary of the Wenchuan Earthquake" was mainly based on the six dimensions, which including the number of reports, the genre of the report, the subject of the report, the source of the information, the tendency of the report, and the type of the report. What’s more, there are differences in the collective memory of the Wenchuan earthquake constructed by commemorative reports of paper media of different natures and regions. The media construction strategy of collective memory in the "10th anniversary of the Wenchuan earthquake" mainly includes two dimensions: content level and form level. At the content level, the social facts, collective representations, and collective meanings are selectively constructed, while at the formal level, periodic elaboration and repetition are carried out by means of commemorative ceremonies. The construction meaning of the collective memory of the Wenchuan earthquake is manifested in the maintenance of the identity and imagined community. Taking the Wenchuan Earthquake, a shocking event at home and abroad, as an opportunity to stimulate, awaken and strengthen the public's perception of the "China" and "Chinese nation" imagined community, thereby enhancing the recognition of Chinese and overseas Chinese for China and the Chinese nation.
