The Spatial Development Characteristics And Pattern Of Erhai Lake Basin In The View Of Ecological Civilization

Man-land relationship is the eternal subject and the main direction of geography research,the stage of human civilization development has been gradually transition from industrial civilization to ecological civilization,harmonious coexistence between man and nature is the basic state of ecological civilization stage man-land relationship.Actually human activities are always based on a certain geographical space,the supply of earth's surface space is limited but the needs of human are unlimited,space scarcity has become an inevitable characterization between Man-land relationship,only by building ecological civilization and improving the pattern of land development can realize the coordination between human activities and space,the bright future of the production space with intensive and efficient use,the living space with being livable and amenity and the ecological space with green mountains and clear waters will come ture.This article attempts to consider man-land relationship as the basic theory of the research,form the view of ecological civilization to research the space development of drainage area,intend to provide a practical evidence for space optimization of Erhai Lake basin,and to provide theoretical basis for study of space development.Full text is divided into six chapters:The first chapter is introduction that introduces the research background,research significance and research ideas.Based on the theory of man-land relationship and ecological civilization,the strategy of ecological civilization construction,the contradiction between space development and protection,put forward the source of problem in this paper.Through literature study,clarify research emphasis about space development both at home and abroad to provide referential significance of the research of this paper.Comprehensive research background and the research achievements of predecessors,puts forward the research train of thought in this paper.The second chapter is ecological civilization and development of space.This chapter is the theoretical basis of full text research.To interpret ecological civilization with man-land relationship and to survey space development with ecological civilization,combing the main types and space base of human activities,and analyze the relationship between them,then extende out of the spatial structure of land development,besides,unscramble the connotation and meaning of the production space,living space and ecological space.The third chapter is the development characteristics of Erhai Lake basin.Based on analysis of production function,agricultural,industry and tourism distribution of Erhai Lake basin is centralized,the first industry development is weak but secondary industry and tertiary industry development showed a slight advantage,the ecological level of the industry has generally declined,some townships have higher ecological level.Based on analysis of living function,the population urbanization level of Erhai Lake basin is slightly below the Dali Prefecture and Yunnan Province,The spatial structure of urbanization is the pattern of "central leading and pole support",in recent years,rural lifestyle and facilities guadually improve step by step.Based on analysis of ecological function,ecological space of Erhai Lake basin is wedge shape,the ecosystem function and value difference are wide in different townships.The fourth chapter is the space development pattern of Erhai Lake basin.Based on the analysis of the types of human activities and the functional characteristics,take townships as units,dividing the production space as agricultural production space,industries-services space and tourism production space,spatial structure is "multi-core linkage","a nuclear dominant" and "dual-core tripartite confrontation",respectively.Dividing the living space as urban living space and rural living space,spatial structure is "a main a","multiple-center",respectively.Dividing the living space as urban ecological space,natural ecological space and resource ecological space,spatial structure is"a main a","multiple-center" and "a nuclear dominant,muhi-point supporting",respectively.The fifth chapter is space optimization strategy of Erhai Lake basin.Scarcity is the power of space development,spatial heterogeneity is the basic for the development of space,space structure is the key to space development,policy regulation and control is the guarantee of space development.From the target orientation,functional orientation and optimization direction to put forward the optimized path of production space,living space and ecological space.The sixth chapter is conclusion.On the basis of summary the main conclution of this article,expecte to continue to study in the following two aspects.One is the research on the dynamic change of spatial distribution about production space,living space and ecological space,second is considering land use types as spatial analysis unit for spatial pattern analysis.
