Research On The Complex System Of Geographical National Conditions And Its Regionalization

The statistical analysis of geographical national conditions is an important part of geographical national conditions survey and monitoring. It is the transformation and promotion of geographical national conditions survey data into geography national conditions information. It is a necessary means and stage to reflect the spatial distribution of resources, environment, ecology, economy and society, and play an important role in promoting the application of survey results and spreading the survey and monitoring of geographical national conditions. The regionalization of geography national conditions complex system can intuitively reveal the interaction and mutual influence of resources, ecology, environment, population, economy, society and other factors. It is a theoretical guide to understand the characteristics of geographical national conditions and discover the law of geographical national conditions, is an effective means and method of statistical analysis, but also can reflect the results of geographical national conditions statistical analysis. The research of geographical national conditions regionalization, on the one hand, which can express the geographical national conditions information, is a comprehensive and intuitive performance of multi-source geographical national conditions data; On the other hand, it is a quantitative expression of the statistical analysis results of geographical national conditions.It is an urgent problem that how to inherit and play the advantages of traditional surveying and mapping, to realize the dual transformation of thinking and technology in the research of geography national conditions. Only in this way, we can avoid the phenomenon of "massive data, knowledge-poor". The dissertation studies the regionalization construction and analysis of geographical national conditions, mainly focuses on the concept and expression of geographical national conditions complex system, the classification regionalization based on cluster analysis and multidimensional scaling, the graded regionalization based on DPSIR model, TOPSIS and DEA, the adjustment and determination of regionalization, regionalization analysis. Aimed to the existing problems, the dissertation established the relevant models and proposed reasonable solutions. The main research work and innovation of this dissertation are as follows.1. The concept of geographical national conditions complex system is proposed, and the quantitative expression is made. As a complex synthesis consisting of man and nature, geographical national conditions is complex systems including resources, ecology, environment, economy and society. The geographical national conditions complex system can break the traditional independent state of every factors, and systematically analysed the theory system of resources, environment, ecology, economy and social subsystems, and organically integrate them. The complex system theory provided a new theoretical guidance for geography national conditions statistical analysis. Coordinate degree is an important method for complex system measurement analysis, providing a new idea for the measurement of the relationship between geographical national conditions.2. The principle and method of index selection for geography national conditions complex system are analyzed. The index of classified regionalization and graded regionalization for geography national conditions complex system were selected respectively, and the corresponding index system was constructed based on DPSIR model. The decision analysis method of geography national conditions complex system is designed. According to the development state evaluation of geography national conditions complex system's subsystem, coordination degree between subsystems, coordination degree of geography national conditions, this dissertation made decision analysis on the overall coordination situation of geographical national conditions, and determined the direction of restoration and improvement of geographical national conditions, and developed appropriate adjustment and improvement strategies to achieve the goal that resource, environmental, ecological, economic and social subsystems were most coordinated.3. The regionalization models including classified regionalization and graded regionalization for geography national conditions complex system were constructed. Through the classification and grade of geographical national conditions complex systems, this dissertation achieved an abstract, highly integrated description of the geographical national conditions classification and quantitative evaluation, and its visual expression. Geographical national conditions complex system explained regionalization from the view of resources, environment, ecology, economic and social. It is not only the method and process of geographical national conditions statistical analysis, but also the result of comprehensive statistical analysis.4. According to cluster analysis and multidimensional scaling, this dissertation designed the model and method of geographical national conditions complex system classification regionalization. The results of multidimensional scaling analysis of geographical national conditions can guide effectively the selection of the initial clustering number and clustering centers in k-Means clustering. Then, according to the clustering results, the clusters were explained and defined, and the combined features and genesis of each type were analyzed. Finally, the classification regionalization map of geographical national conditions complex system is generated. Taking the Henan Province as an example, this dissertation makes an experiment and analysis on the classification regionalization of geographical national conditions of Henan Province on the basis of the geographical national conditions survey data, and then verification of the method proposed in this dissertation.5. TOPSIS is used to evaluate the development state or classification index of subsystems in complex system. DEA is used to evaluate the coordination among the subsystems in complex system. On this basis, a universal evaluation model of the coordination of multiple complex system is designed. According the graded regionalization index system and the evaluation model, the coordination evaluation method of geographical national conditions complex system is proposed. this dissertation makes an experiment and analysis on the graded regionalization of geographical national conditions, and the improvement measures of coordinative development for Henan Province geographical national conditions had been drew up.6. Based on the classification regionalization and graded regionalization of geographical national conditions complex system, this dissertation designed the adjustment and determination method of geographical national conditions complex system by the correlation coefficient and the variation coefficient. The overlay analysis, spatial correlation analysis and correlation pattern analysis were carried out on the regionalization of geographical national conditions complex system, found the potential knowledge and rules of geographical national conditions survey data and its associated statistics data.
