Urbanization Under The Background Of Urban Construction Land Intensive Utilization Research

Since the 21 st century, China has entered the rapid urbanizationofstage, the demand for land, especially the urban construction land needs to be very inevitable. But, our country land resources nervous, land use efficiency is low compared with developed countries. As the rapid development of urbanization, the outward expansion of city scale is very serious, occupied with good suburb of cultivated land, threat to national food security further. Therefore, urban rapid development of the construction land intensive use saving research is necessary, urban construction land intensive use saving help urban healthy development and the stability of the national food security.Experience in land use theory at home and abroad for reference, this study, on the basis of field investigation and data analysis, to rent land, sustainable development, such as location theory as the theoretical support, from the perspective of theoretical research and empirical research both the importance and urgency of the urban construction land intensive utilization. Adopts the method of qualitative and quantitative analysis, combining with the analytic hierarchy process(ahp), mean square error, a comprehensive evaluation method, linear regression analysis method, the key to build in baoding city urban construction land intensive utilization evaluation index system of saving, analysis of baoding city in 2004-2013 time series of urban land intensive utilization change and the intensive degree of various spatial difference.By studying the main conclusions obtained are as follows:(1) through the data analysis and theoretical elaboration, shows that urbanization and urban construction land intensive utilization is complementary relationship. Among them, the urban population, industrial structure, urban scale, technology level, economic development and government policy on the level of intensive utilization of urban construction is vital to the improvement. On the other hand, improve the urban construction land intensive degree can also help the smooth progress of urbanization.(2) the relative abundance of data, current situation of urban construction land intensive utilization in baoding city dynamic contrast analysis, found that the construction land supply, land use structure is not reasonable; Urban development model of a single, lack of three-dimensional development; The government and the market mechanism is not close; The ecological environment deterioration trend; In view of the urban land intensive utilization monitoring mechanism is not sound; Intensive consciousness of public.(3) the intensive utilization of urban construction land index quantitative. Based on land use degree, land input intensity, the efficiency of land use and land use ecological benefit from four aspects, selected 16 indicators factors constructing evaluation index system of intensive construction land use in cities and towns, the town of baoding city from 2004 to 2013 is analyzed on the time series of intensive construction land use change and its various counties in the city of the level of intensive use of space. The results showed that intensive urban construction land of baoding city in 2004-2013 level in general is on the rise, but still in a lower level of intensive utilization, and baoding city to reduce the degree of intensive space of various regions is of remarkable difference.(4) based on the intensive construction land use in cities and towns of baoding existing problems, puts forward some corresponding countermeasures and Suggestions. Including: the residential areas, clean up the idle land; Construction land supply and orderly, industrial land use structure optimization; Explore the urban three-dimensional development pattern; Combined with the government and the market, the effective management of land market; Land consolidation in harmony with the ecological environment, to ensure the healthy development of the town; Improve the system of dynamic monitoring and early warning; Consolidate the consciousness of intensive use of land, deepen the concept of reasonable land use.Innovative: from the perspectives of research, the research on intensive construction land use of baoding city is relatively small, in baoding city as the research object of urban construction, built in view of the baoding city urban construction land intensive utilization evaluation index system. From the research methods, choose the linear regression analysis method and analytic hierarchy process(ahp) and quantitative qualitative analysis, and put forward the view that baoding city urban construction land intensive level remains to be further improved, urban planning and implementation, government supervision and market allocation of resources needs to be further strengthened.
