Comparison Between Urban Planning Core Controlling Technologies Of America And China In The Stage Of Detailed Plan

The main function of the urban planning is for controlling and leading the city to develop in an orderly manner,which can generally be divided into master plan and regulatory plan in China. The key control technology of urban planning in detailed plan stage of China is Regulatory Plan as carrier, which includes the establishment and management. The key control technology of urban planning in detailed plan stage of U.S.A. is Zoning Resolution as carrier, which includes the establishment and management.This paper introduces the key control technology of urban planning of China and the United States in its background, development course, establishment content, manage the characteristic, extant subject problem and position in Urban planning system. To Comparative and research, it is especially in developing process, position and function, establishment content and managing. It compares the origin, essential factor, achievement in establishment content comparison process, and decision-making, execution, Feedback in manage comparison process through the System theory. Finally this paper uses the comparison experience between China and the United States for reference to the key control technology of urban planning of China. While comparing from the process of developing, it thinks that the regulatory plan developing from present technology to the guide which implements the policy, and pay attention to the realization of public interests in management. While comparing from the Position and function, it thinks that promoting regulatory plan of controlling. and accelerate legislation their especially, make city land used for determinacy of structure strengthen. While comparing from working out the content, it thinks that setting up modern property relations and promoting standardization to control index, strengthen behavioral restraint and elasticity to control index of procedure. While comparing from management, it thinks that controlling many power centre in management, and controlling and guiding the planning implement different depth of the polymorphic type, creating the regulatory plan and comprehensive control technology led in grades.In general, the zoning law system relatively meets the urban environment of slowly development at present, while the regulatory plan system meets our country city of high-speed development. Inosculate them is the long-term subject for research. Recently it should focus on and draw lessons from and improve from the relevant technological aspects of public policy of city.
