技术发展日新月异，人们进行交流和沟通的平台也逐渐延伸到网络中。近年来，爱国主义精神和实践也不断向网络空间拓展，“网络”成为了“网络爱国主义”的存在方式和运作场域，网民们在掀起爱国主义热潮的同时，也产生出有别于传统话语的话语体系和表达方式。这种网络表达极具复杂性和易感染性，对网络情绪的爆发、网络舆论的形成和舆情态势的发展都有极其重要的推动作用。国际大型体育赛事往往能够激发国人的爱国情感，而国际奥林匹克运动会作为全球性的大型国际体育赛事，对中国人来说更是有着特殊的意义。

因此，本文在前人研究的基础上，梳理了网络爱国主义的演变路径，并以2021年东京奥运会和2022年北京奥运会的微博评论为例，从主体特点、呈现形式、内容议题、话语框架、话语风格五个维度，分析了新媒体环境下的网络爱国主义话语体系。在话语体系分析的基础上，又进一步从情绪表达、行为表达和表达路径三个维度分析了网络爱国主义的表达机制。研究发现，在奥运语境下的网络爱国主义表达中，网民们不仅关注赛事消息、表演仪式和国家荣誉等宏大场面，也更加关注运动员本身的个人特质和内在品质，对不同国家、种族的运动员也表现出尊重和喜爱，用一种国际主义的态度去看待这场体育盛事，从侧面彰显了国人因自强而产生的由内而外的民族自信。在民众的情感表达和行为表达中，网民们愈发用一种兼容并包和开放进取的态度面对事情，承载着民族记忆，践行着时代情怀。

但是，在网络爱国主义话语表达中，谣言四起、过分娱乐、极端情绪等网络乱象仍是突出问题。这不仅不利于新型国际关系的构建，更不利于中国“走出去”和在国际社会发挥更大、更积极的作用。为了解决在网络爱国主义表达中的非理性因素，本文也从媒体、政府、企业和个人四个话语主体的角度提出了相关的对策，以期营造良好的网络爱国主义舆论生态，更好的凝聚社会共识，推动社会发展。

With the development of Internet new media technology, the Internet has long become an important platform for people to exchange information and group socializing. In recent years, the spirit and practice of patriotism have been expanding into cyberspace, and "Internet" has become the mode of existence and the field of operation of "cyber patriotism". While stirring up the upsurge of patriotism, Internet users have also produced discourse systems and expressions that are different from traditional discourse. This kind of network expression is extremely complex and easily infectious, which plays an extremely important role in promoting the outbreak of network emotions, the formation of network public opinion and the development of public opinion situation. Large international sports events can often arouse the patriotic feelings of Chinese people, and the International Olympic Games, as a large global international sports event, is of special significance to the Chinese people.

Therefore, based on previous research, this article summarizes the evolution path of online patriotism, and takes Weibo comments from the 2021 Tokyo Olympics and 2022 Beijing Olympics as examples to analyze the discourse system of online patriotism in the new media environment from five dimensions: subject characteristics, presentation form, content topic, discourse framework, and discourse style. On the basis of discourse system analysis, the expression mechanism of online patriotism was further analyzed from three dimensions: emotional expression, behavioral expression, and expression pathway. Research has found that in the context of the Olympic Games, in the expression of online patriotism, netizens not only pay attention to grand events such as event news, performance ceremonies, and national honors, but also pay more attention to the personal characteristics and internal qualities of athletes themselves. They also show respect and love for athletes from different countries and races, and view this sports event with an internationalist attitude, From the side, it highlights the national confidence generated by Chinese people's self-improvement from the inside out. In the emotional and behavioral expressions of the public, netizens are increasingly adopting an inclusive and open attitude towards things, carrying national memories and practicing the sentiment of the times.

However, in the expression of online patriotic discourse, rumors, excessive entertainment, extreme emotions and other online chaos are still prominent issues. This is not only detrimental to the construction of a new type of international relations, but also to China's "going global" and playing a greater and more active role in the international community. In order to address the irrational factors in the expression of online patriotism, this article also proposes relevant countermeasures from the perspectives of four discourse subjects: media, government, enterprises, and individuals, in order to create a good online patriotic public opinion ecosystem, better consolidate social consensus, and promote social development.
