摘　　要：选用湘潭市1996年土地利用详查和1997-2005年期间土地利用变更数据及相关经济统计数据，分析了城镇建设用地的时空变异特征；通过构建城镇建设用地驱动指标体系，运用主成分回归分析法对城镇建设用地变化的驱动力进行了分析探讨。初步研究表明：湘潭市城镇建设用地增长存在明显的阶段性变化特征；各类城镇建设用地变化的空间差异明显，且具有向城镇边缘及沿主要交通干线向周边丘岗山地扩展的特点；导致湘潭市城镇建设用地时空分异的主要驱动力分别为城市人口增长、城市化、工业化以及经济发展。Based on the detailed survey data of land use in 1996, the updated data from 1997 to 2005 and relevant socio-economic statistical data, the spatial-temporal variability of urban construction land use in Xiangtan, Hunan province is researched. A driving indicator system of urban construction land use is established. The driving forces are then analyzed by the principal component regression method. It is shown through the results that there exists an obvious periodic variation of the growth of urban construction land and that there is a great amount of regional difference among various kinds of urban construction land as well, the main expansion direction of urban construction land change being the vicinity of the edge of town and major traffic route of the hilly mountain. The main driving forces are identified as the growth of population, urbanization, industrialization and economic development.
