This paper takes the redevelopment of Donghuamen Relic Park(and its surrounding area)in the CBD of the old city of Chengdu as a research object, and makes an analysis of the core of the"Conceptual Planning of Donghuamen Relic Park of Chengdu" with theory of the production of space from the perspective of Neo-Marxism, by finding that in the process of conceptual transformation,city images changed from "Donghuamen Historic Site" to "Donghuamen Relic Park" then to "central park of CBD," while the "production of space" was disguised of "construction of place." And by the means of blurring concept, monopolizing discourse,differentiating the city image, symbolizing the historical culture, the government still continue to seek "land finance" from urban renewal, which did not turn to inheriting historical culture and constructing local characteristics due to the planning and constructing of new CBD in Tianfu New Town.
