土地利用转型,即在社会经济变化和革新的驱动下,某一区域在一段时期内由一种土地利用形态转变为另一种土地利用形态的过程。在中国,耕地和农村宅基地乃土地利用转型的重要源头。本文综合利用2000年和2008年两期LandsatTM影像解译土地利用数据及2000-2008年国土资源部土地利用年度变更调查数据,分析了中国耕地和农村宅基地利用转型的时空耦合特征。研究表明：①2000-2008年期间,中国耕地面积与农村宅基地面积变化的相关系数为-0.921,呈现出明显的增减逆协同演进格局;②耕地—宅基地变化相关系数与农村宅基地利用变化率的Spearman等级相关分析结果表明,在耕地和农村宅基地利用的相互转化过程中,农村宅基地利用的变化起主导作用;③通过计算全国各省2000-2008年间的耕地—宅基地变化耦合系数,发现期间耕地和农村宅基地利用变化耦合程度高的省份主要分布在胡焕庸线的东南部。社会经济—生物自然—土地管理三维驱动因素通过＂农村人口—耕地—农村宅基地＂三者之间的相互联系与相互作用驱动着耕地和农村宅基地利用的转型。然而,耕地和农村宅基地利用转型的时空耦合现象及其发生机制在很大程度上要归因于中国特殊的城乡二元结构社会体制。

英文摘要：

Land use transition refers to the changes in land use morphology of a certain region over a certain period of time driven by socio-economic change and innovation, and it usually corresponds to the transition of socio-economic development phase. In China, farmland and rural housing land are the major sources of land use transition. This paper analyzes the spatio-temporal coupling characteristics of farmland and rural housing land transition in China, using high-resolution Landsat TM （Thematic Mapper） data in 2000 and 2008, and the data from Reports on China＇s Land-use Survey and Update during 2000-2008 released by the Ministry of Land and Resources of China. Conclusions are summarized as follows： 1） During 2000-2008, the correlation coefficient of farmland vs. rural housing land change is-0.921, showing that the change pattern of farmland and rural housing land is uncoordinated; 2） The result of Spearman rank correlation analysis of the change rate of rural housing land and the correlation coefficient of farmland vs. rural housing land change shows that rural housing land change has played a major role in the process of farmland and rural housing land transformation from each other; and 3） During 2000-2008, a high-degree coupling is found between farmland and rural housing land change in the southeast China, based on the calculation of the coupling coefficient of China＇s farmland and rural housing land change at provincial level. In general, farmland and rural housing land transition in China is driven by socio-economic, bio-physical and managerial three-dimensional driving factors through the interactions among rural population, farmland and rural housing land. However, the spatio-temporal coupling phenomenon and mechanism of farmland and rural housing land transition in China are largely due to the ＇dual-track＇ structure of rural-urban development.
