Abstract:“Copernicus Revolution in Literature Study”is the praise for Lotman’s healing the internal research and external research gap and eliminating the science and humanities boundaries by early domestic academics. Currently, Lotman is facing contextualization again and his cultural identity being changed. In terms of value position, domestic academics incline their theory to deconstruction and cultural poetics, emphasize its theoretical deconstruction factor and postmodernism style. From theory of forms angle, domestic academics committed to activate Lotman’s magnificent culture from the perspective of semiotics, linguistics, history of philosophy, literature, history, cultural history and interdisciplinary characteristics and methodological essence from single orbit of structural semiotics to multiorbit development of cultural semiotics. Lotman transformation of the original image not only opens up the Lotman theory of the horizon, but also inspires the" posttheoretic era" of literary and cultural studies.
