Research On Geographical Space Optimization In The Context Of Ecological Civilization

As the basic requirement and national development strategies,ecological civilization has been included in the overall layout of " Five-point Strategy ",and has been widely recognized by the whole society in China.The Nineteenth National Congress of the Communist Party of China regards "Sticking to the harmonious coexistence of human and nature" as the basic strategy for upholding and developing socialism with Chinese characteristics in the new era.The 2018 National Conference on the Protection of the Ecological Environment regards it as an important principle that must be adhered in advancing the construction of ecological civilization in the new era.Therefore,it is imperative and important duties to be performed for Chinese governments at all levels to promote the construction of ecological civilization and put it into practice.At present,the prominent problem of regional ecological civilization construction is not lack of theory,but the transformation of theoretical guidance into practical operation and the promotion of ecological civilization construction.For example,for local governments,one of the key issues is how to integrate ecological civilization construction into geographical space development,accordingly making ecosystem concept of "Mountains,rivers,forests,lakes and grasses are the life community" the solid foundation of the green development concept of " Lucid waters and lush mountains are invaluable assets",and therefor realize the harmonious coexistence of human and nature.As a subject with human-land relationship as its main research object,one of the main tasks of human geography is to focus on the dynamic relationship between environment and society,to promote regional development's transition towards sustainable development mode,and to build a bridge between science and decision-making.Therefore,based on the discipline system of human geography,it has great theoretical and practical significance to innovate the methods of ecological civilization construction and geographical space optimization,comprehensive and in-depth understanding of the complex human-earth system,and then better serve the decision making.This research mainly includes seven parts: The first chapter is introduction,which introduces the background,purpose,significance,basic content,possible innovations,research methods and technical routes.The second chapter summarizes the research progress at home and abroad,main theories and basic problems of ecological civilization,the development of geographical space,and chooses three typical cases at home and abroad to analyze from the practical level,draws inspiration from theory to practice.The third chapter analyses the close relationship between the construction of ecological civilization and the development of geographical space from perspectives of scientificity and decision-making.The forth chapter puts forward the analysis principle of geographical space optimization,collects and collates the basic data of different main functional spaces in Gansu Province,calculates the spatial structure proportion relations of four main functional spaces in Gansu Province and fourteen cities and prefectures in detail,and analyses the characteristics of land spatial structure according to the present situation of land spatial development,put forward an optimization scheme of geographical space structure.The fifth chapter designs the coordination degree function of geographical space development around the core issues of geographical space development and construction of ecological civilization,calculates the coordination degree of resources-environment-ecosystem,population-resources-environmentecosystem,economy-resources-environment-ecosystem and geographical space deveopment in Gansu Province and 14 cities and prefectures.The changes of coordination degree under the influence of single factor and multi factors are analyzed comprehensively.Based on the calculation results of coordination degree of geographical space development and the present situation of geographical space structure,the geographical space development patterns of Gansu Province and 14 cities and prefectures are analyzed quantitatively,then put forward an optimization scheme of coordination degree of geographical space development.The sixth chapter combs the quantitative analysis method of geographical space development pattern,clarifies the objectives,principles,contents and index system of geographical space optimization,and puts forward the method of geographical space optimization.Then,taking the construction of ecological civilization as the goal,optimizing the structure of geographical space development and improving the coordination degree of geographical development,the paper puts forward the policy suggestions of geographical space optimization of Gansu Province and 14 cities and prefectures respectively,and constructs the geographical space optimization model based on the construction of ecological civilization.The seventh chapter summarizes the research conclusions,discusses the existing shortcomings and future directions that need to be further improved.This study attempts to make theoretical innovation and application expansion on geographical space optimization basing on the land evaluation of the Major Function Oriented Zoning,and the results mainly embodies the following points: 1.From the perspective of human geography,this paper defines the practical connotation of ecological civilization,and holds that in practice.The core of ecological civilization construction is to adjust human-land relationship,Human-land system coordination is the common core of ecological civilization construction and geographical space development.The main path of ecological civilization construction is the optimization of geographical space development pattern,which can be realized by optimizing the external space structure and improving the coordination degree of internal factors.2.Based on the requirement of ecological civilization construction,the principle of geographical space analysis is clarified.Four new types of main function spaces are named,survival space,ecological space,production space and reserve space.Taking Gansu Province as an example,the spatial structure relations of four main functions in Gansu Province and 14 cities and prefectures are quantitatively analyzed.3.The concept of "coordination degree of geographical space development" is coined.The coordination degree function of geographical space development including five categories and eight indicators such as population,resources,environment,ecology and economy etc.The optimization method of geographical space development pattern aiming at the construction of ecological civilization is designed,and bring forward niche targeting policy proposals on the provincial and city level perspectively.
