A Theoretic And Positive Research On Urban Comprehensive Carrying Capacity

Urban is the concentrated area of the population distributing,the resources consumption and the environment pollution.With the dramatic growth of the urban population and the fast extending of the city scale,it is gradually becoming the common focus of the society that the carrying capacity of the resources and environments restrict the development of the city.The harmony between the urban sustainable development and the carrying capacity of the resources and environments not only affect the future destiny of the urban,but also relate to the realization of the sustainable development objectives of its peripheral region.Based on above,the dissertation aim at systematically defining the core concept of Urban Comprehensive Carrying Capacity(UCCC),refining the main factors of UCCC, conceiving the structural model of UCCC,analyzing the function mechanisms of UCCC,designing the evaluation indicators framework,making out the counterpart early-warning tactics and selecting target city to make the positive research according to the key elements to support the sustainable development of the urban population and social economic activities.Thus it can provide the macro regulation,the government management,the performance appraisal and the policies make-out with the theoretic reference.The.main content of the dissertation can be concluded the follows.Chapter 1 firstly illustrated the research aim,background and significance.Secondly,it systematically reviewed the relevant literature.Finally,it indicated the research content and its realization methods of UCCC.Chapter 2 mainly demonstrated the theoretic base for the research of UCCC such as Complicated System(CS),Urban Economic (UE),and Sustainable Development(SD) and Multi-attribute Decision(MAD) theories and so on.Chapter 3 mainly introduced the evolution of UCCC,defined the concept of UCCC,analyzed the characters of UCCC,conceived the structural model and its elements and indicated that the functions and objectives of UCCC.Chapter 4 concluded the dynamic evolution of the concept and research of UCCC,analyzed the conditions,the motivations,the ways and the scenarios of UCCC,indicated that the factors to affect the dynamic evolution of UCCC and put forth the evolution modes of system and function of UCCC according to the dynamic evolution mechanism of CS. Chapter 5 firstly analyzed the synergy content and framework of UCCC,then conceived the mutual action model of UCCC,finally analyzed the mutual action mechanisms according to the synergy and mutual action mechanism of CS.Chapter 6 mainly illustrated the concept and characters of the brittleness of UCCC,analyzed the elements and process of the collapse resulted from the brittleness,and indicated the collapse appearance of UCCC and its application according to the brittleness collapse of CS.Chapter 7 mainly put forth the core idea and principles of the evaluation of UCCC,designed the counterpart evaluation indicators,determined the power of each indicator based on Triangular Fuzzy Number Analytical Hierarchy Process(TFAHP) and then formed the integration appraisal framework.Chapter 8 firstly conceived the main early-warning indicators of UCCC,secondly refined the key indicators through Main Composition Analysis Method(MCAM),thirdly conceived Multiple Variable Return Model(MVRM) to forecast the changes of UCCC,thus put forth the counter tactics and plans to enhance UCCC.Chapter 9 put UCCC theories into practice to make the positive research.The dissertation indicated the concurrent situations of Beijing city that is a typical target city,analyzed its main problems based on the water carrying capacity through the evaluation system,and then made the counter tactics. Chapter 10 firstly concluded the whole dissertation content,and then indicated the main innovations,the limitations and the prospects.The main innovations can be concluded the follows.Firstly,the dissertation put forth the structural model and elements of UCCC,Secondly,the dissertation analyzed such mechanism of UCCC as dynamic evolution,synergy mutual action and brittleness collapse and so on.Thirdly,the dissertation designed the evaluation framework of UCCC based on TFAHP.Finally,the dissertation conceived the early-warning evaluation model and dynamic forecasting model based on MCAM and MVRM. Additionally,the dissertation put forth the counter tactics and plans to enhance UCCC.Therefore,The dissertation conceived the whole theoretic system of UCCC through defining the basic framework,conceiving structural model,analyzing system mechanisms,evaluating UCCC,making out the enhancing tactics of UCCC and doing the positive research and so on.I believed that the theoretic system will not only provide the relevant theory research with the theoretic reference,but also instruct the specific practice of UCCC in our country.
