Reserch On Urban Planning With Extenical Methods

The problems in urban planning system gradually develop to tendency of comprehensive and complex. Information involved in these problems is also too much, and is difficult to handling. For urban planning subjects, complexity and contradiction of the problem always is the core of solution to the problem. In the process, if they can be targeted with theory and method of guidance and information processing tools auxiliary, planners can efficiently solving these problems.Extenics is a new subject which use logic language to describe and analyze the contradictory problem by establishing quantitative analysis model, attempts to solve many stress to the perceptual, abstract problems, which are difficult to use logical initialization language to describe before. These characteristics of Extenics help to use visual logic language to interpret complex thinking and creative process in urban planning, then summarizes the design rules for the realization of artificial intelligence, which helps to improve work efficiency.Proper theories and methods are chosen from Extenics system in research on urban planning based on the Extenics, which are extension thinking, extension set and extension transformation, transforming bridge method are used in research on urban planning based on the Extenics, and land layout, space design, management control rules, three aspects are composition of the urban planning. Research problem with different properties determine the solution also are different.Plan design is the most fundamental in research on urban planning. City land contains lots of independent city land, and each independent city land have their own unique geographical location, cultural traits, economic value, environmental quality and various factors of the influence. These independent land interact each other, produce intricate relationships, thus formed the complex and changeable city land pattern. In the complex conditions, it's easier to applying research methods of first macro then microscopic. At first, independent city land are analyzed, and then established the problems related net to analyze the macro angles city land utilization, with using relevant tree, extension set and extension transformation method to describe and solve the urban land layout design problems faced by the various contradictions.Space design is in microscopic field of urban planning, different from master paln and zoning planning, it's a kind of detailed planning of urban space design, and it's necessary for comprehensive consideration of the architectural entity, set space, environment shaping the combination of various elements of the mutual relationship with integral layout. In applying first micro then macroscope research methods, at first thinking modes of Extenics is used in the space design process involved in various factors, we can describe and analyze the microscopic level of analysis results; then to establish the relationship between the network forming macro analysis model by all sorts of microscopic analysis results, this method can meet the various conditions of planning and design scheme.Management regulation is the most complex research in urban planning. It's content refers to non-drawings achievements in various parts of the planning scheme, performance in text, control guideline for planning and other forms. In the application of first micro then macroscope research method, extension thinking mode, problem contains system are used to analyze the independent manage regulation from microscope angle, by establishing problems related net to analyze the macroscopic angle of manage regulations, turning conversion channel, extension set and extension transformation method are used to describe and solving manage regulations, facing in the various contradiction problems.The effectiveness of the method system only can be proved through the practice. Harbin master plan (2004~2020) is compiled by Harbin urban planning and design institute, using Extenics methods to describe and analyze have realistic meanings. According to project characteristic, dimension table system was used to describe, with Extenics research methods in the land layout, space design, management regulation, overall analysis of the project can be completed.Through theoretical methods research and analysis of the projects, this paper discusses the possibility and vista of cross-research on Extenics and urban planning, and also pointed out further research direction in this field.
