| Organic city is a city model formed under the guidance of organic thought. Under the background of new era, the organic city and its development pattern has produced new changes. Organic city has two characteristics: one is urban system itself with the body of a living organism has the same structural and initiative; inherent reason of urban development on the other hand, showing a virtuous circle, and to be able to build maximally meet the healthy living of urban residents. This paper through in-depth investigation of Chongqing Bishan district and Wuxi city of Jiangyin, in the existing research results on the basis of reference organism theory, bionics theory, city ecology theory, circular economy theory and the theory of sustainable development, the organic city thought connotation, definition and characteristics of the city organic and organic city model building, the formation of science awareness of organic city comprehensive, and on the basis of constructing the evaluation index system of organic City, establishing a logical starting point and starting point of the analysis, by using the econometric analysis, examples of test methods, from the two dimensions of quantitative and qualitative evaluation method of comprehensive index of organic City, to explore the development path and organic city effect of organic texture factor and city improvement, and explore the city development under the principle of organic City. On this basis, we get the conclusion of this paper and put forward the corresponding optimization ideas and suggestions.The content of this article is from the structure can be divided into introduction, basic theory research, specific research and analysis, case study and application and countermeasures suggested five parts of a total of six chapters.Chapter one is the introduction, main content involves background research, clarify the research problem and the problem of the research clearly define the scope, and further clarify the research purpose, significance and perspective, clarifies the research content, thus combing the logic of research ideas and appropriate use of research methods, in problem solving research also show the innovation of the research.The second chapter is a part of fundamental research: first of all, in the idea of the city, of organic urban thoughts and its similar both urban idea of qualitative research and definition and through horizontal and vertical comparison that organic city idea is different from other existing characteristics of the idea of the city. Secondly, in urban pattern, in western urban development patterns were combing research, summarized the rules of urban development patterns, focus on the "urban organism" model of development, for the establishment of organic urban pattern lay a theoretical basis. Finally, evaluation index system for the existing urban development patterns of classification research, summed up the urban development pattern evaluation techniques, methods and standards, to provide technical guidance for the establishment of the evaluation indicator system of urban organic. The above content provides a theoretical support for the research of this paper.Chapter three to chapter four specific research and analysis part: this part consists of two chapters, the connotation of the definition of the first chapter focuses on the urban organic thought evolution process, organic urban thoughts and the thought of urban organic and in organic city thought based on the proposed organic city(mode); the second chapter is establishment of a systematic and scientific evaluation index system, make further quantitative study on organic city idea and mode, and put forward the urban organic criteria, to further improve the composition system of urban organic.The fifth chapter is the application research: through the analysis of Bishan and Jiangyin municipal case on the structure and evaluation system of urban organic for confirmatory testing. For two cases of cross comparison, and try to explore further under the influence of the same period in different areas, culture, economy and population factors of urban organic composition and construction characteristics, provide examples of support for urban organic classification, structure and system development.The sixth chapter is the conclusion part: the main contents of this chapter are divided into the following points:First, a careful analysis of organic urban thoughts, organic urban pattern and evaluation system of urban development in China, and to the full text of the study by combing summary.Second, specific analysis in organic city under the guidance of the characteristics of the development of different cities, advantages and restrictive factors of, on the specific implementation method of organic city make a summary.Third, based on the analysis of the research, conclusions and suggestions on the problems of further research prospect. |
