On The Protection Of The Historic Urban Environment Design

Urban historical environment is the physique the city left behind. From 18 century to today, people have protected it in the round. The protective area has been from individual historical architecture to individual historical architecture around, from historical region to the whole city. The protective mode has been from congealing mode to the mode that protection and renovate tie in. Urban design is the organizing for urban physique environment in urban space, it has gonethrough five periods-the design of before urbanization, the design of form creed, the design offunction creed, the design of configuration creed and the design of humanitarian creed. The protection of urban historical environment and urban design are inseparable. The protective design for urban historical environment is what the protection of urban historical environment and Urban design combined, it means we can carry out protecting urban historical environment by the meansof urban design. It is explanation of time-space view, it means we can compress time factorinto urban space. We should stick to the whole principle, the dynamic principle, the zone principle, the multiplicity principle and zoology principle in the protective design for urban historical environment. People have had a lot of study and gained some theories or modes in the protective design for urban historical environment. They are the theory of organic order of Eliel.Saarinen, the mode of collage city of Rowe.Colin, the theory of urban imago of Kevin.Lvnch, Japanese theory of metabolism city and intergrowth city, the theory of site spirit of Norberg.Schulz, the mode of analogous city of A.Rossi and the theory of pattern language of C.Alexander.We can protect urban historical environment by the means of urban design, which has three arrangements in city. The first arrangement is individual architecture that involves in historical architecture and new architecture. Historical architecture involves in itself and historical architecture around.. New architecture involves in optic protection and nonfigurative protection for urban historical environment. The second arrangement is historical region. We should do design in miniature little by little because historical region is complex. The design means of nonfigurative inherit is a good means for historical region. The third arrangement is the whole city, it involves in different cities. Some cities have whole historical scene, so we should focus on the design of plane setup, urban layout, urban contour line and architectural style. The others should adopt the means of network design. Urban renewal is the focus in the protective design for urban historical environment, it involves in all arrangements before. We are facing a lot of difficulties and having a lot of problems during urban renewal of our country, we should take measures to solve them.
