Urban Architectural Culture Heritage Space Environment Information Model Research

City architectural space environment, cultural heritage is the core of urban architectural culture heritage building can intact, the existence and development of health of soil, is also an integral part of human history information to the public display of the stage. Urban architectural culture heritage of space environment protection of urban architectural culture heritage is of great significance to the survival and development. The development of science and technology, the continuous renewal of urban civilization, usually leads to alternate between old and new, the contradiction between traditional culture and new culture extinct,and whether the conflict management is proper, often influence the development of social civilization, how to better deal with the contradiction, is we need to focus in current research.Information technology continues to progress and development, urban development and construction has gradually entered the information age, filled with convenient and efficient.There are a lot of people think that the application of information technology in urban development, is the end of the cultural heritage of architecture, make a lot of historical space into the way of information exists, there will be no meaning. But it is a myth, it is the wrong understanding of the process of informatization. City informatization process, I believe, for one of the architectural culture heritage is not an end, but a continuation, on a continuation of the geographical space, and extension of information space. Only we through to the information and urban architectural culture heritage protection, this paper explores the to find the balance point of the two, in the process of increasing the degree of informationization,more clear accurate expression of architectural space environment protection cultural heritage,has its own characteristics, thus forming the construction of information technology.The development of information technology, to the city space environment building cultural heritage protection brings new ideas and ways. The acceleration of urbanization, more and more have retained and protection value of urban architecture devastating destruction of cultural heritage, for those who have been protecting and restoring urban architectural culture heritage, people expect more intensification of protection.Through exploration and summary we is not hard to find, the development of the city buildings to space brings new problems of environmental protection, cultural heritage is irreversible damage problem in the first place, the second is the complicated need fine heritage in the construction of city space environment protection, the last is rapid city update the impact on the architectural cultural heritage has a huge stack of historical information. The three problem solving process is also in this article we study the urban space environment building cultural heritage information model is established in this paper, the process of the thesis tries to use virtual reality technology for the first problem is resolved, according to thesecond problem through the analysis of the space environment simulation platform of BIM to fine protection scheme, according to the last question by forming a to achieve integration information platform of protection purposes.
