Study On The Theory And Method Of Extension Urban Ecological Planning

Theoretical research of city ecological planning is not only an important research field of urban planning,representing the future direction of development, but also in the field of urban planning a new theory and method of the platform. This paper based on Extenics theory, with city planning and ecological planning, from foundation theory and theory framework, some aspects such as method system, planning program and content, have carried out system research, have founded theoretical frame and method system of extension city eco-planning preliminarily. Meanwhile, it provided theoretical support and approach platform for computer aided solving the contradiction problems of ecological planning.Firstly, theoretical foundation of extension city eco-planning has been discussed. Including of theory evolution of city ecological program, have demonstrated extensionality of city ecological planning and its contradictory problems, present research system. established basic theory for the later working.Fundamental theory of extension city eco-planning was established preliminarily, its definition was put forward that it is an urban eco-planning based on Extenics, is a new theory & method of urban eco-planning for solving its contradictory problem, and realizing its goal. It does not only replace original theory, but enriched them. Based on basic-element of Extenics theory and urban ecology, it put forward concept, characteristic and types of basic-element of city eco-planning; drawing support from extension modes to describe & express numerous and complicated problems, it has made it clear that the research of this paper, aiming at solving its contradictory problem, by means of building problem extension modes, extension analysis, extension transformation etc. achieved the solution of ecological planning problem; Urban eco-planning based on extension thinking modes are expounded. They are combined with extension and city ecological program in basic theory together.On the foundation of theory framework of extension city ecological planning, its method system is presented. Following ecological planning problem-oriented, it carries out researching its application method. Namely, its method of problem finitude, problem analysis, problem transformation and problem solution. Meanwhile, it simulates a few solution process of urban eco-planning case, and inspects and verifies its rationality. The establishment of method system provides a good path for computer aided urban eco-planning.The process of extension city ecological planning is put forward, this is a deepened content and the improvement of method against traditional city ecological program. Its' program has divided 4 stages: preparative stage and ecological investigation stage, analysis transformation stage and program production stage. Its establishment make method system have gotten to extend, have offered program guarantee, for solving formally ecological contradictory problems have offered process support for the specific operation of theoretical accomplishment.From city region and urban, street district layer,paper discuss major content of city ecological program, have extended the application scope of theoretical method. Through simulating different example of the ecological planning, it formally express solution course of contradiction problem, have verified the reasonability of theory and method of this paper; have solved some actual problems of ecological planning. This is reification or extraversion of theoretical method of the city ecological program. For further theoretical application to establish foundation, it is a specific practice application of city ecological program research about extension architecture design theory.In a word, Theory and method of Extension city eco-planning are based on Extenics, city eco-planning and urban planning, this paper will integrate them to Cross-over study, it have founded preliminarily its' theoretical framework. On this foundation, it have founded method system, planning process and major content, and gotten certain innovation accomplishment. It opens up the new field of the city ecological program theoretical research in city development theory, offers a new method and solution means for city ecological program contradictory problem, enriches the theory and method of city ecological program. it is a kind of improvement of existing eco-planning in aspect of operability formalization and clarity, has promoted the intelligent and quantitative development of city ecological program, the thesis tries to provide theoretical principle and approach platform for computer to solve the contradictory problems of eco-planning.
