Northwest China Landscape Beautification Comprehensive Zoning Study

This dissertation comes from the nation item " the graceful landscape with green mountains and clean and limpid rivers (GLGMCR) 's the expermenting area construction and important science and technology problem researches of different ecosystem region in the Chinese northwest", it is the expected study of the prophase regionalization, very necessary for the GLGMCR construction. GLGMCR 's comprehensive regionalization research is to carry on the comprehensive evaluation to the ecosystem, economy, social factor of every area, and provide the theories and implements bases for the GLGMCR construction, aiming at the northwest region's different characteristic of ecosystem environment and the concrete target of the GLGMCR of everyplace.The main researches contents is as follows::(1)The theories and method of the GLGMCR 's comprehensive regionalization;(2)The establishment of the index system of the GLGMCR's comprehensive regionalization;(3) The establishment of management information system for the GLGMCR 's comprehensive regionalization;(4) Case study.By investigating, this paper carries on a deep research for the comprehensive regionalization theories, method, establishment of index system of the northwest region, and takes concrete realization of the GLGMCR 's comprehensive regionalization of ShaanXi province based on the system theory, information theory, the ecosystem economics theories and sustaining development theories, applying the Analytic Hierarchy Process (AHP) , fuzzy cluster analysis and GIS spatial overlay analysis, which lead to the following research results:1. Analyzing the various regionalization results and the method systemsMany research results have been achieved about the nature regionalization. It is the foundation of comprehensive regionalization to analyze the results and theories of the previous research. Because the comprehensive regionalization consists of three systems of the ecosystem- economy- social, therefore, it is a very complex system, we make a deep research in the principle and targets of ecosystem, economy and the social development in northwest...
