Because of the special social and cultural background,underdeveloped ethnic areas in Western China have become the exact areas with the lower level of development,and its urbanization has been the more difficult thing to promote,which are the weaknesses in the process of urbanization development both at national and regional levels.Under the new historical period and developmental ideas,promoting urbanization in underdeveloped ethnic areas in Western China is an important part of building a well-off society and sharing development achievements by the whole people.To study the process of urbanization in underdeveloped ethnic areas from the perspective of internal coupling and coordination can build the pathway from non-coordination to coordination development,which is based on the logic of construction of reverse thinking and problem diagnosis.It is of great theoretical and practical significance to enhance the cognition and quality of urbanization and to promote the intensive use of resources within the system and the coordinated development of the region.The complexity of urbanization with different scales mean the research areas will be more difficult both in breadth and depth.The complexity of population and geography and the richness of contents are reflected on the research of different pattern and distinctive areas.Underdeveloped together with multiculture,the urbanization system in this kind of areas,how to analyze the basic concepts,develop features,types division,evolution mechanism etc.the basic theoretical research and to extract the basic theoretical framework for this kind of area with the particularity and typicality?Based on the theoretical researches,how to study the spatial and temporal evolution pattern of its urbanization system via quantitative study and to build the coordinated development model of urbanization?According to the literature on urbanization at domestic and abroad in recent years,less research on the coupling and coordination between the internal subsystems of urbanization has been done,the micro-scale urbanization system research in underdeveloped minority areas are lacked especially.A complete system has not yet formed on systematic research of urbanization,which needs to be improved in terms of research scale,index selection and method system.Based on the spatial justice and flow spatial theory,a series of related concepts have been defined with the help ofspatial analysis software and data analysis software.Coupling coordination model and structural auto regressive model and other research methods are employed in this paper to study the spatial-temporal correlation and regional differentiation characteristics of Population-Land-Economic(PLE)urbanization system in Linxia Prefecture from 1996 to 2015,the mechanism of urbanization system coupling is analyzed in a dynamic way,so the optimal control strategy of PLE urbanization system in underdeveloped minority areas is constructed,in order to accelerate the urbanization process and improve the quality of the typical areas.The research contents and main conclusions of this paper are as follow:Firstly,the coordination of urbanization system lies in the coupling and coordination of “system---structure”,“system---scale” and “speed---level”.Secondly,the urbanization process of Linxia Prefecture is generally better,but its development is still slow compared with other regions of Gansu Province and even the whole country.The scale and grade of cities and towns are at a lower level,the industrial development is not balanced,and the intensive use of urban land is low.At the same time,the five problems in the process of urbanization development in Linxia Prefecture are pointed out.Thirdly,the model of PLE urbanization system coupling coordination in Linxia is constructed to analyze the coordinated development process of PL urbanization system,PE urbanization system,LE urbanization system and PLE urbanization system in Linxia is in time and space.Linxia City and Yongjing County are outstanding "star" areas in the process of urbanization development in Linxia Prefecture.Fourthly,constructing the stable model of structural has strong explanatory ability to PLE urbanization dynamic mechanism in Linxia Prefecture.The results of causality test show that the role of population urbanization is obvious for both land urbanization and economic urbanization in Linxia,and the role of economic urbanization in population urbanization is obvious.The results of impulse response show that the positive impact of population urbanization on both land urbanization and economic urbanization system is quite obvious,and it also shows a trend towards long-term stability.Land urbanization has a positive impact on population urbanization and economic urbanization,but it has a great impact on itself.The positive impact of economic urbanization on population urbanization is evident in both short-term and medium-term.The results of variance contribution show that impact of population urbanization on land urbanization and economic urbanization is the most obvious one.Fifthly,the goal of coordinated optimization of PLE urbanization system in underdeveloped minority areas is to generalize population attraction,optimize land carrying capacity and strengthen economic support.The main contents of regulation and control are as follows:firstly,to liberalize the household registration system and accelerate the absorption of agricultural transfer population;secondly,to reform the land system and reconstruct compact urban spatial planning;thirdly,to promote the regional coordinated development layout through the agglomeration of related industries;fourthly,to ensure the supply of the system and to enhance the institutionalinnovation of the government's effective measures.The innovations of this paper include:Firstly,to identify the process of agglomeration and diversification.According to the different steps of social system,the develop characteristics of Linxia Prefecture have been analyzed.To study the changes of its population,land and economy etc.within the research period is to analyze the venation of urbanization in Linxia Prefecture.Making the problems existed in the urbanization in Linxia Prefecture clearly will clarify the coordinate and systematic development ideas of population-land-economy urbanization in underdeveloped ethnic areas.Secondly,to depict the spatial and temporal pattern.The relationship between systematic coupling and coordinate development of PLE urbanization system in Linxia Prefecture has been whole depicted both from two systems and three systems from the dimensions of time and space.Choosing the rational index,establishing the model of urbanization systematic coupling and coordinate development,taking the characteristics of different subsystems in the different spatial positions into consideration will provide the further understanding for systematic and coordinate development rule of population-land-economy urbanization in underdeveloped ethnic areas.Thirdly,to analyze the dynamic mechanism.Based on the data of subsystems chronological order of urbanization in Linxia Prefecture,the systematic relation of population urbanization system,land urbanization system,economic urbanization system and their rate of contribution have been evaluated.Given the static analysis previously,analyzing the mechanism and the intensity of population urbanization,land urbanization and economic urbanization will open the “Black Box” of mechanism of urbanization in underdeveloped minority areas,and further enrich the experiment of population-land-economy urbanization in underdeveloped ethnic areas.
