Controlled Urban Design Function Duality System In Operation

After its conception was brought forward independently, Moden Urban Design has been more arid more popular in a short period. Not only it's study scopes extend largely in depth,width and span, but also the involved people including designer, governor and all the citizen have touched upon all kind of social positions or ranks. URBAN DESIGN , the production and cosset of the pluralistic thought of design, has such a complicated backgroud which involves plenty of factors that we should pay attention to: style of the social organization, form of the economy development, statute systems and so on and so forth.Academe in China began to put attention and developed their study in this thesis at 1980's. Most of the design problems have got a new dimention of thought after that: urban site planning, transportation organization, enviornment landscaping, urban conservation and renewal, steet landscaping, pedestrian design, fa9ade reconstruct etc. Before long, insurgent waves of urbanization bring us lots of "urban design" items. Without forearmed, flurried architects and planners work out many kinds of urban design "productions" which have different depth, degrees of statutes, tangly functions and unable to put into application.-what's wrong with them ?According to the experience about the theoretics of urban design,we then get some standpoints of our own.The most important thing we need is to develop a rational and canonical procedure for urban design operations. In other words, we should work over some technique policies to protect urban design operations.Function duality system of urban design illuminatd by this article, is a research on this thesis for urban design operations. Inthis funcion system we will focus on the design categery,funcions,operation procedure and power in use.
