Port And City Of Coupling Mechanism And Analog-control Study

With the accelerating process of economic globalization, global economic center of gravity shift to the coastal port city trend becomes more obvious, the port city to enhance our national competitiveness as the key. " to promote port by urban, to promote the urban areas by port, balance urban and port development" is the universal law of development of the world's ports. The development of urbanization in China is fast in this period, but have not formed a world type of port city. The coupling mechanism between port and urban is not smooth is the key factor which led to the weak comprehensive competitiveness. Thus, choose a typical area to research the coupling mechanism, laws and analog control between port and urban development and in order to provide theoretical and practical support, is related to our economic and social development subject. Based on low-carbon economy, sustainable development requirements, This paper comprehensive geographic science, systems engineering, information science, management theory and methods, adhere to the theory comes from practice principles to guide practice in turn, follow the "content-mechanism-Evaluation-law-policy "research ideas, focusing on the coupling mechanism and reveal the system control system design, attempts to explore both theoretical and coupling system, and research applied to the practice of Lianyungang city.Based on consulting many documentaries at home and abroad, the paper summarizes the research course,research results and future research direction of the relationship between port and urban,from which we can seek breakthrough point of the researeh.From the port and urban system and its constituent elements influence each other to form the PU framework which reflecting the complex relationship between port and urban,emphatically analyzes the coupling mechanism is that the internal structure decided to inner behavior, and environment and rule are also the important factors which influence the coupling system.Using the entropy theory of dissipative structure theory to founded the external discriminant system, using system dynamics of causality analysis and investigation of the inner harbor coupling system structure. Using qualitative analysis and quantitative analysis method, constructed the city coupling index screening procedures based the PU framework; comprehensive analysis on the basic situation of lianyungang city coupling, with the index screening program establishes lianyungang city coupling index system. Basis by the City system entropy determination mode analysis of coupling between 1996-2008 coupled condition of Lianyungang City, as the external behavior and function of the measure.Looking from the perspective of dissipative structure, city-urban is a system of dissipative structure supported by external environment of nature,society and economy,based on coupling between systems of port and urban both temporal and spacial. According to the analysis of its evolution process,the system develops towards a orderly and senior direction through fluctuations of its size.To make the system to achieve low entropy and orderly state, and must make the system open, and gets from the outside world enough negative entropy flows. The Law of evolution of the system is the system evolution over time, there is the process of bifurcation, to ensure the evolution of the system in the right direction, you need to play at a critical moment to rely on the multiplier effect of the negative entropy flow to ensure that the system entropy decreased.According to the port and urban coupling characteristics, this paper established PU-SD model in coupling between port and urban, which analyzed multiple feedback mechanisms of port-urban coupling system and interactive process of each system. Taking Lianyungang City in Jiangsu Province as an example, the model which has been proved reliable and applicable,choose relevant parameters as control variables for strategic scenario simulation. The results indicate that it is necessary for lianyungang to change the structure and use of development planning of resources to achieve the port-city coordinated and sustainable development. The paper puts forward maero-eontrol eountermeasures to promote the interaction of Port and urban.
