【摘要】：土地是人类社会经济活动的主要载体,区域发展过程中出现的问题均可以在土地利用上得以反映。作为区域发展子系统的乡村发展与其土地利用的变化息息相关,而耕地又作为典型农区的主导地类,因此开展乡村发展与耕地利用转型问题的综合研究,对协调区域发展与耕地利用、保护的持续矛盾,促进乡村可持续发展与耕地集约、高效利用等,具有重要的理论与实际意义。本文研究主要内容与结论：(1)从空问、用地、社会、经济等方面界定了乡村发展的概念,其可概括为外延发展与内涵发展。耕地利用转型分为显性转型与隐性转型两种类型。(2)运用关系矩阵法分析了用地转型的时序关联性,运用邻接关系法分析了用地转型的空间关联性。探讨了土地利用类型不同空间组合状态对土地利用转型的影响、转型强度、转型优势倾向。研究表明,作为典型的农区,耕地与村镇用地是其主要的用地类型,二者占全县总面积的比重高达90.62%。耕地利用显性转型易受相邻地类的驱动或制约,尤其是村镇用地。耕地与村镇间的转型是曲周县土地利用转型的主导。时序上,耕地向村镇用地的显性转型呈逐渐减弱趋势。(3)从空间发展、用地集约发展、社会经济发展三个维度构建了乡村发展评价体系,从耕地利用显性转型、隐性转型角度构建了耕地利用转型评价体系。运用属性层次模型对乡村发展、耕地利用转型进行了综合评价。依据制定的类型划分标准把曲周县划分为快速发展、中速发展、低速发展3个一级发展类型及3个二级主导发展类。社会经济发展、空间发展则是快速发展型的主导,快速发展型主要围绕着各乡(镇)的中心分布。而离乡(镇)中心较远的区域其发展水平相对较低,用地集约则是其主要特点；耕地利用转型以隐性转型为主,其与耕地利用综合转型具有明显的空间一致性。相对耕地利用中、低转型,显性转型在高转型中的比重较大。(4)二者问具有较高的耦合性,从耦合度、耦合量两个方面确定了曲周县乡村发展与耕地利用转型的6个耦合主导类型。耦合协调发展度呈不断上升趋势,从2000年的0.6676上升到2013年0.8020,并处于勉强协调发展阶段(2000-2007年)与中等协调发展阶段(2008-2013年),协调发展呈逐渐转好态势；随着乡村发展水平的不断提高,乡村发展与耕地显性转型耦合协调度呈现先增大后减小的态势,而与隐性转型呈逐年增大的趋势；2000～2007年为乡村发展滞后型,主要因为以空间发展为主导的乡村发展总体水平不高,而以显性转型为主导的耕地利用转型幅度较大所致。2007年后为耕地利用转型滞后型,此阶段以社会经济、用地集约为主导的乡村发展较快,乡村的空问外延得到了有效控制。因边际效应等的影响,以隐性转型为主导的耕地利用转型幅度较小所致。(5)曲周县乡村发展引致耕地利用转型程度呈先增加后减缓趋势,后期乡村发展对耕地利用转型影响契合经济学边际效应递减规律。2030年左右单位乡村发展水平的耕地利用转型达到极佳状态,此后乡村继续发展但对耕地利用显性转型变化影响极小。(6)从乡村空间发展与耕地利用显性转型的角度,利用CA-Markov模型,从规划、生态等方面制定调控规则,优化模拟了影响极限时的曲周县用地空间格局,并对其稳定性进行检验；从乡村内涵发展等角度,探讨了促进耕地利用隐性转型的合理调控途径。
[Abstract]:The land is the main carrier of the economic activities of human society, appeared in the process of regional development problems can be reflected in the land use change. As a subsystem of the regional development of rural development and land use are closely linked, and farmland as the dominant typical agricultural areas, so to carry out comprehensive research on rural development and land use transformation problem, to coordinate regional development and land use, sustainable protection contradiction, promote the intensive rural sustainable development and efficient utilization of cultivated land, etc., has important theoretical and practical significance. This paper studies the main contents and conclusions: (1) from space, land, social, economic and other aspects of the definition of rural development. It can be summarized as the extension development and content development. Land use transition is divided into two types as the dominant and recessive transformation transformation. (2) using the relation matrix method to analyze the timing of land transformation. Together, using the adjacency relation method to analyze the spatial correlation of land transformation. To investigate the effect of different types of land use spatial combination state of land use transition transition strength, transformation tendency. Research shows that the advantage, as a typical agricultural area, cultivated land and rural land is the main land use types, accounting for two the proportion of the total area of the county up to 90.62%. land use dominant transformation vulnerable types of drivers or adjacent constraints, especially the rural land. The transformation of cultivated land and villages between the Quzhou County Land Use Transition led. Timing, cultivated land to town land dominant transformation was decreased (3) from the space. The development, the development of intensive land use, the three dimensions of social and economic development to build the evaluation system of rural development, the transition from the dominant land use, construction land use transformation evaluation system transformation angle. Using the implicit attribute hierarchy model of Township Village development, land use transformation was evaluated. According to classification standard to Quzhou county is divided into rapid development, the speed of development, low development level of 3 development types and 3 grade two class. Leading the development of social and economic development, spatial development is leading the rapid development of the rapid development mainly around the township (town) of the distribution center. And the village (town) the development level of central remote areas is relatively low, intensive land use is its main characteristics; land use transition to recessive transition, and the land use transition space has obvious consistency. The relative use of arable land, low the transformation, transformation in the transformation of the dominant high proportion. (4) two Q coupling has a higher coupling degree, from two aspects, coupled to determine the amount of rural development and land use in Quzhou County, the 6 main types of transformation. By coupling the coupling coordination The development of a rising trend, rising from 0.6676 in 2000 to 0.8020 in 2013, and is barely coordination development stage (2000-2007 Years) and the coordinated development of middle stage (2008-2013 years), the coordinated development is gradually improving trend; with the continuous improvement of the level of rural development, rural development and land transformation of dominant coupling coordination degree increased at first and then with the trend of decreasing, while implicit transformation was increasing year by year trend; 2000~2007 years for rural development lag, mainly because of the overall level of rural development in the space of development is not high, but by the dominant transformation led land use transition due to the larger.2007 years for the cultivated land use transformation lag, at this stage of society the economy, land intensive oriented rural development rapidly, rural space extension has been effectively controlled. Because the marginal effects of the recessive turn led to Land use transition caused by a small margin. (5) the village of Quzhou county development caused by land use degree of transformation was first increased and then slow down the trend of rural development, the late transformation on the impact of land use with the law of diminishing marginal effect of economics around.2030 units of rural development level of arable land use transition to achieve excellent condition, then the country continue to develop but to the cultivated land the dominant transformation changes a little influence. (6) from the village space development and land use in the transformation of the dominant point of view, using the CA-Markov model, from the planning, ecological and other aspects of the development of regulatory rules, optimization of simulated the effects limit the Quzhou County land use spatial pattern, and to test the stability of the country; from the perspective of connotation development, explore reasonable regulation to promote the transformation of land use implicit way.
