The Increase And Decrease Connecting Potential Analysis And Empirical Research On Urban And Rural Residential Land

Land, being the carrier of all human activities, is the most important natural resource and productive factor, and is the premise and base of economic and society development. In order to plan the coordinate growth of cities and towns, to effectively solve the contradiction between urbanization, industrialization and cultivated land protection,"Pilot Management Methods of Connecting the Increase in Urban Construction with Decrease in Rural Residential Land" is raised by the national innovation existing land use management system. By using these management methods of CUR (connecting the increase in urban construction land with decrease in rural residential land) policy, the pressure of urban and rural construction land supply is retarded, rural productive and living environment is improved, rural urbanization and modernization is accelerated.Under this circumstance, it has an important theoretical and practical significance to analyze the capacity and research the spatial distribution of CUR. On the one hand, the CUR theory is enriched and completed. It is practical to broaden research area of land reclamation, providing theoretical reference to land policy innovation. On the other hand, measuring CUR potential can provide data reference to all areas applying CUR pilot, distributing CUR index, launching CUR project, and lay a foundation to land renovation plan.The combination of theoretical research and empirical study is applied in this research. On the basis of CUR related concept definition, land utilization planning, supply and demand of land, sustainable development, location theory, and differential land rent and other theories are used to analyze the influencing factor and the potential measure model choice of CUR. Tianjin city is used as the example to thoroughly and systematically study CUR demand, CUR supply, CUR division, CUR model and CUR balance index distribution.The prime tasks innovation points of this research are:(1) On the basis of related literature review, the theoretical foundation of the CUR is system combed. The guidance function of different theories to CUR work is discussed.(2)From deciding peg implementation necessity to CUR effect influence, the influencing factors of CUR are deeply analyzed. CUR potential analysis related regression an-analysis; method of moving average and weighting method are presented and chosen.(3)Tianjin city being the example, CUR potential analysis and spatial distribution are empirically analyzed. CUR measurement method and the potential technical route based on overall plan of land utilization is first raised. The foundation of application CUR pilot, distribution CUR index and CUR project is laid.(4)Many suggests to promote the smooth development of CUR work are put forward, providing decision making reference to the pilot projects being conducted CUR work in Tianjin city and even the whole nation. Science and operability are strengthened.
