The Town Of Regional Pree System Defined In The Yinchuan Plain And The Coupling Correlation Analysis

Since the implementation of western development strategy, China’s western region, the trend of rapid urbanization significantly, to undertake the industrial transfer of the eastern part of Northwest environmentally fragile areas of socio-economic level to significantly improve the ecological environment is facing increasing pressure. The urban area is a complex adaptive system composed of a population, resources, economy, environment, multistability, non-linear, dynamic changes in the characteristics. Urban regional system evolution of the adaptive cycle characteristics of the multiple associated nested development. Urban regional system evolution of the adaptive cycle characteristics of the multiple associated nested development. The study of urban regional sustainable development is the ongoing problems in the process of the regional evolution of study towns. So.the definition of the Urban Regional PREE and multiple associated mechanisms to characterize the scope of the urban region level, the overall trend, power factor, the multiple correlation mechanism. For in-depth study of the Yinchuan Plain urban regional development potential of profound meaning.In this paper, the town area of the Yinchuan Plain is as the object of study. Summarized the main achievements of recent years on urban regional development, sustainable development and the PREE coordination of Development Research, defined urban areas. PREE related concepts. The use of temporal and spatial analysis methods and comparative analysis, Yinchuan urban population of the region, resources, economy, environment, development process and the spatial distribution pattern was studied. Through the establishment of evaluation index system and the degree of coupling econometric model to explore the area of the town in such a special location and natural conditions, evolution of population, resources, economy, environment and associated coupling mechanisms. Principal component analysis methods, and coordination model on the Yinchuan Plain urban regional systemwide coordination of the Regional PREE degree to do a quantitative calculation, then explain the mechanism of evolution of multiple correlation system based on the results analysis.
