The Evaluation Research On Ecological Carrying Capacity Of Zhongyuan Urban Agglomeration

Today, the world is facing a series of problems of Global warming, Resources and Environment damage, Population expansion and so on. Facing the predicament of the development of major issues, humans began to reflect on their behavior, think about the future development mode, and the way of sustainable development is an inevitable option. Realizing the sustainable development of our urban agglomeration determines whether the sustainable development strategy in China. Based on the background, evaluate and research ecological carrying capacity of Zhongyuan Urban Agglomeration, find out ecological environment problems and seek solutions, has very important practical significance.This paper is divided into four parts:The first part is the first chapter, introduces the background of the topic and proposes research topic, determines the research target, ideas and methods. Through reviews of the research situations about bearing capacity, ecological carrying capacity and urban ecological carrying capacity, to analyze the development direction of ecological carrying capacity.The second part is the second chapter. Through the related research, define the concept of urban ecological carrying capacity, analyze factors and theoretical foundations of urban ecological carrying capacity. The third part including the third to the seventh chapters, empirical research ecological carrying capacity of Zhongyuan Urban Agglomeration. First from natural resources, social economy, urban development and ecological environment, introduces the basic situations of Zhongyuan Urban Agglomeration. Second analyzes urban ecological carrying capacity of target and index system principles, determine the evaluation index system of Zhongyuan Urban Agglomeration. By using entropy method calculate weight, and using state space method to evaluate, bases on the domestic and foreign relevant documents, standards established under the condition of sustainable development, and the ideal situation value. From social, economic and ecological environment of three subsystems respectively, and comparatives study Wuhan city circle and Changsha-zhuzhou-xiangtan urban agglomerationin. Aims at the evaluation results, proposes the problems existing in the development and relevant countermeasures. The fourth part is the eighth chapter, summarize the methods and research results in the article, specific analysis insufficient in the research work, and put forward the improvement measures and future prospects.The datas in this paper come from social, economic and environment aspects about Zhongyuan Urban Agglomeration and inner cities in 2007. Using extreme normalized method to process these datas, and using the state space method to evaluate. Compares with wuhan city circle and changsha-zhuzhou-xiangtan urban agglomeration lastly.This innovation for: Using qualitative and quantitative methods to do systematic analysis about internal subsystem of Zhongyuan Urban Agglomeration and nine cities, and also compares with wuhan city circle and changsha-zhuzhou-xiangtan urban agglomeration.Research results show that: In 2007, the urban ecological of Zhongyuan Urban Agglomeration are serious overloading, the pressure of economic development is large, belongs to an unsustainable development. Compares with other parts of the central region to show that the central urban development status is similar, ecological pressure difference are heavy. The pattern of economic growth, the adjustment of industrial structure change urgent task is still heavy.
