Evaluation And Prediction Of The Urban Niche Of The Beijing-Tianjin-Hebei Ministry

At present,with the deepening of the process of economic globalization,regional integration has become the mainstream trend of economic development in the future.As a key development area of urban integration process,Beijing-Tianj in-Hebei junction area is in the stage of rapid development of integration process,the industry in this study area is continuously transferring and upgrading,and the level of social and economic integration is constantly deepening.However,with the deepening of regional integration process,the problems of uneven development level,unreasonable allocation of resources and extensive industrial development are gradually exposed in the administrative region of Beijing-Tianjin-Hebei junction area.Therefore,this study used niche theory and SD model to evaluate the urban niche of Beijing-Tianj in-Hebei junction area,and analyzed its influencing factors,forecasts its future urban development,and puts forward corresponding countermeasures and suggestions,which provides some reference for the efficient integration of other cities in china.First,this paper discusses the research of city ecological niche research background and significance,reviews the related literature collection,discusses the connotation of related concepts and theoretical foundation;After that,this paper introduces and analyzes the basic situation of the research area,and introduces a large number of data sources and their processing methods in the process of research;Then,based on the design principles of the evaluation index system,this paper establishes the index system of urban ecological niche evaluation in the study area and establishes the index standard value and the weight,based on these results,the ecological niche width,ecological niche index and niche overlap index of the study area were measured and the causes were analyzed;Finally,this article will use the system dynamics theory to design the system dynamics model of urban development,and predicted that 2020 specific level of urban development in the study area,then put forward the future research area by relying on the developing countermeasures.
