【摘要】：城市化是现代社会发展的趋势,其发展势必与一个国家或者区域的土地资源的利用是否合理化有着不可分割的联系。城市化进程的加快伴随着一系列的社会、经济和环境问题,对城镇的可持续发展造成一定的影响。另外城市化无限外延扩张的发展模式占用了大量的优质耕地,致使耕地数量锐减、土地投入产出比下降等,从而造成城市化发展与土地利用不协调发展。因此研究土地利用效益与城市化的耦合协调关系,不仅有利于相关地区土地管理、土地政策的制定工作,实现城市的可持续发展,同时对钦州市实现城市化和土地利用的协调以及土地高效利用有着重大的现实意义。以钦州市为研究区域,借鉴国内外土地利用效益与城市化的相关概念和理论体系,分析2013年钦州市钦南区、钦北区土地利用现状以及城市化发展历程,分别从土地利用的土地经济效益、土地社会效益、土地生态效益和人口城市化、经济城市化、社会城市化六个方面选取了22个指标来构建土地利用效益与城市化耦合协调发展体系,通过耦合协调度模型、相对发展度模型、相关性模型来对钦州市土地利用效益与城市化耦合协调度模型进行了定性定量的分析,得出以下结论：(1)根据2013年钦州市钦南区、钦北区的土地变更数据分析,结果表明农用地占的比重最大,其次为建设用地与其他土地。通过分析土地利用动态情况,得出2003-2013年钦南区、钦北区土地利用类型年变化率最大的均为交通运输用地,其次为园地。通过计算钦南区土地利用的多样化指数Gm为0.77,钦北区土地利用的多样化指数Gm为0.71。(2)2002—2013年钦州市土地利用效益与城市化的耦合度除了2002年处于低水平耦合阶段,其余年份均处于颉颃阶段。耦合协调度经历了轻度失调、濒临失调、勉强协调、初级协调四个阶段。(3)采用相关分析方法研究城市化水平与12个土地利用效益指标之间的相关性。人均城市道路面积、工业废水排放量、工业二氧化碳排放量与城市化发展之间不存在线性相关关系。文中选取的土地利用效益指标中与城市化水平关联性最大的前三个分别为：地均工业产值地均国内生产总值人口密度。基于此从四个方面提出提高钦州市土地利用效益与城市化耦合的建议：优化土地利用结构、城市化发展与土地资源保护协调、合理编制土地利用总体规划和城市总体规划、保护改善生态环境。
[Abstract]:City is the development trend of modern society, its development is bound to use with a country or area of land resources is reasonable are inextricably linked. Along with the city to accelerate the process of a series of social, economic and environmental problems, have a certain impact on the urban development model of sustainable development. In the city of infinite extension and expansion of the occupies a large number of high-quality arable land, resulting in land population and land input-output ratio decreased, resulting in city development and land use coordinated development. So the research of coupling coordination between benefit and city land use, land management not only conducive to the relevant area, land policy formulation and realize the sustainable development of the city, and the implementation of city and coordination of land use and land utilization has great significance in the city of Qinzhou in Qinzhou city. As the study area, from the related concepts and the theory of benefit and the city land use system at home and abroad, Qinnan District of Qinzhou city in 2013 analysis, current situation and development of city land use in Qinbei District, from the land use of land land economic benefit, social benefits, ecological benefits of land and population of the city, city economy and society city six aspects of 22 indicators were selected to construct the land use efficiency and city coupling coordinated development system, through the coupling coordination degree model, the relative development model and correlation model of coupling coordination model and the efficiency of city land use in Qinzhou city makes qualitative and quantitative analysis, draw the following conclusions: (1) according to the Qinnan District of Qinzhou city in 2013, Qinbei district land change data analysis, the results show that the maximum proportion of agricultural land accounted for, followed by the construction land and other land. Through the analysis of Land use dynamic, the 2003-2013 in Qinnan District, the type of annual change rate was the biggest transportation land use in Qinbei region, followed by the garden. By calculating the land use diversity index Gm of Qinnan is 0.77, the land use diversity index Gm is 0.71. (2) in Qinbei District of Qinzhou city from 2002 to 2013 land by using the coupling efficiency and the degree of the city in 2002 at a low level in the coupling phase, the rest of the year were in the antagonistic stage. The coupling coordination degree experienced mild imbalance, the imbalance, force coordination primary coordination four stages. (3) the correlation analysis method of city level and 12 land use efficiency index correlation between City Road area per capita, industrial wastewater emissions, there is no linear relationship between industrial carbon emissions and city development. The land use efficiency indicators are selected The level of relevance in the city with the largest top three respectively are: industrial output is GDP population density. Based on this proposed to improve the efficiency of the proposed coupling and city land use in Qinzhou city from four aspects: the optimization of land use structure, development and protection of land resources of city land reasonable coordination. The overall planning and the overall planning of the city, to protect and improve the ecological environment.
