Research On Construction Lands Changes And Driving Forces Of Chizhou City

Purpose of the research are that as Wanjiang city belt of urbanization level and GDP per capital is much higher than the province average level, but per capita construction lands at lower levels, it has a certain representation and typicality, this paper analyses the status of the construction lands of Chizhou City, revealing the problems in the process of the construction lands expansion, and discussing the driving factors of construction lands changes, promoting the economical and intensive use of construction lands, and to revitalizing the stock of rural construction lands and construction lands increase or decrease hook, promoting the development of a coordinated interaction between urban and rural areas, providing technical and practical supports for relevant policy making.Methods of the research are that theoretical research and empirical analysis method, combining the cross section study and diachronic research the method of combining qualitative and quantitative analysis method of combining.The findings showed that,(1)This paper analyses the total of the construction lands in Chizhou city from2002to2010,finding that construction lands from2002to2010with53412.02hectares and41776.35hectares growth in Chizhou City and Chizhou city construction lands change of elasticity coefficient is significant,2003,2006and2009, elasticity coefficient is higher, showing that this three years of construction lands growth significantly higher than the population growth,bringing very great pressure for lands resources.(2) There is still a great distance between the construction lands use structure information entropy and the standard entropy of Chizhou city construction lands use structure (Nat)1.1in Chizhou City,and information entropy was0.632010(Nat) is lower than the standard entropy of0.47(Nat), showingthat construction structure to become disordered development, Chizhou advantage degree is low, the construction lands structure shows that the construction lands structure tend to be more balanced, more conducive to sustainable development of lands.(3) The dynamic changes of construction lands in Chizhou city is obviously, and urban village in urban village and industrial and mining lands use change rate is3.03, and the lands transportation speed is0.87, and the rate of0.42lands for water facilities and construction lands speed is3.48.(4)The influencing factors of the construction lands in Chizhou City is a lot, combining with the practical situation of Chizhou City, through construction lands the drive mechanism and various factors correlation analysis, concluded that the main factors influencing the Chizhou city construction lands expansion and the non-agricultural population and the second the proportion of tertiary industry labor, urbanization level, and so on.The results showed that, Population growth in non-agricultural population growth (correlation degree is0.7633), and the strongest correlation is the primary factor affecting the construction lands change in Chizhou City. Industrialization and urbanization factors (correlation were0.7518,0.7416) are to promote the dominant factor on the changes of construction lands, traffic level and industrial structure adjustment are is construction lands scale and structure change of the direct factors, policy factors is construction lands cyclical change of the underlying factors in Chizhou City.
