| 摘 要： | 本研究运用重心分析模型，从移动方向、移动距离、空间相关性等层面，阐述了福建省1985-2010年耕地重心的动态演变规律；通过与同期人口和经济重心移动轨迹的对比分析，探讨了耕地重心时空变化与经济发展、人口增长的空间关系。研究表明，福建省耕地、人口与经济重心均偏于几何中心东南，耕地重心更靠近几何中心，人口及经济重心则偏离显著；耕地重心呈东南-西北方向移动，并渐趋接近于几何中心，与人口、经济重心的空间演变轨迹完全相反。即改革开放以来，福建省人口增长、经济发展重心的南移、东移，是导致耕地重心呈现反向变化的主要推动力；耕地重心与人口重心的移动速度更为吻合，说明人口增长对耕地占用的影响更为直接，人口增长所带来的城镇化过程对耕地的占用，是当前耕地资源所面临的最大的威胁。

| Abstract: | Using gravity-center model, dynamics of cultivated land gravity centers in Fujian province during 1985 and 2010 are examined, from multi-aspects such as moving direction, moving distanceand spatial correlations. By comparing with moving patterns of population and economic gravity centers in the same period, relationships between cultivated land gravity center changes and economic development as well as population growth are elaborated. Results show that the three gravity centers are all located to the southeast of geometrical center of Fujian province. In particular, cultivated land gravitycenters are relatively closer to the geometrical center. For population and economic gravity centers, an obvious deviation from the geometrical center can be observed. During the study period, cultivatedland gravity centers moved from southeast to northwest, approaching closer to the geometrical center. This moving direction was opposite to those of population and economic gravity centers, demonstratingthat the eastward and southward movements of population and economic gravity centers since the reform and opening up were the very impetus. And, the moving speeds of cultivated land and population gravity centers coincide more with each other, reflecting direct impacts on cultivated lands occupation from population growth. The occupation, as a result of urbanization, is nowadays imposing a major threat tocultivated land resource. |
