Public historiography has become an important discourse space for people's survival and development nowadays.Under the background of media convergence, the space for public historiography expression has been expanded and diversified, and the writing and dissemination of public historiography have been characterized by timeliness, diversity and integration.The inclusive characteristics of media convergence make the public historiography writings appear equality and universality. The production of historical knowledge begins to be transformed from the monopoly of elite historians to the socialization. The public's discourse power in historiography is been gradually strengthened, and the new concept of “civilian historiography” has been gradually formed. Writings of public historiography has been constantly deconstructing the original historical narrative framework, and the grand historical narrative and historical concepts of mainstream historiography have been challenged.The combination of public historiography and media convergence is promoting the change of the traditional historiography form and the repositioning of the historical values. 当下,融媒体成了人们生存和发展的重要话语空间。在融媒体背景下,公众史学的表达空间得以拓展并出现多元化,公共历史书写和传播出现了及时性、多样性和融合性的特点。融媒体所具有的包容性使公共历史书写出现平等性和广泛性,历史知识的生产开始由精英史家垄断向社会化转化,公众的史学话语权在逐步加强,新的"民史"观念逐步形成。公众历史书写不断解构着原有的历史叙述框架,主流史学的历史宏大叙事和历史观念受到挑战。公众史学和融媒体的结合,正在推动着传统史学编纂形态的改变和历史学价值的重新定位。
