Study On Symbiotic Synergetic Theory Based On The Integration Of Shenyang City And Benxi City The Integration

With the progress of science and technology, economic development, cities havebecome increasingly mature, bring convenience to people also more and more big,but all sorts of problems also emerged, environmental pollution, ecological imbalance,and the excessive waste of natural resources and overdraft, how to solve theseproblems has become the important issues of urban development.To fundamentallysolve the problem of urban society, resources and environment, must be placed in thecity complex ecological system under the framework of study, considering the citynature, three subsystems of economy and society, will be the third system as a wholetogether.According to the characteristics of ecological system, the urban compoundecological system was divided into three subsystems such as the natural ecologicalsubsystem, economic ecological subsystem and social ecological subsystem. Thestructure graph of urban compound ecosystem was drawn as well. Moreover, theecosystem symbiosis model of urban compound ecological system was establishedwith the synergetic theory and application of efficiency function. The compoundecological system symbiosis degrees and the development trend for Shenyang andBenxi were analyzed by the methods of order parameter choice, order degreescalculation and symbiosis degrees assessment. And Shenyang city and Benxi city theintegration of ecological symbiotic degree of prediction in2015. The results showedthat the compound ecosystem symbiosis degrees for Shenyang from1995to2011hadbeen increased. Benxi compound ecosystem symbiosis in1999-2011degrees upwardtrend is obvious. In2015, after integration，has promoting effect on the developmentof the two cities. With the instance study, the model was proved to be scientific,reasonable and feasible, by which the ecosystem symbiosis level and developmenttrend of urban compound ecological system were evaluated and analyzed.
