为探索甘肃省近十年来耕地集约利用的驱动力，运用综合分析法、聚类分析法以及因子分析法，分析影响其耕地集约利用时空差异的各种因素。研究结果表明：(1)甘肃省耕地集约利用虽在逐年提高，但总体水平较低，增长速度缓慢，时间特征不明显；(2)受到降雨、地形等因素的限制，甘肃省耕地集约利用空间特征较为显著，尤其是以黄河为界，河东和河西的差异比较明显。以2008年为例，集约度最高的是嘉峪关市达到了0.12，而最低的甘南州只有0.05，相差一倍多；(3)通过因子分析法，确定甘肃省耕地集约利用的驱动力主要有社会经济因素、耕作条件及自然因素三类。通过研究发现，甘肃省的耕地集约利用主要受到人口、科学技术水平、政策制度、经济发展、自然灾害的限制。相关部门应该从上述五方面着手提高甘肃省耕地集约利用水平。

In order to explore the intensive use of arable land in Gansu Province over the past decade the driving force, the use of comprehensive analysis, cluster analysis and factor analysis, analysis of the impact of its intensive use of land space and time differences in various factors. The results showed that: (1) Cultivated land intensive use in Gansu province is increased year by year, but the level is low and improved slowly. The time characteristics is not obvious; (2) Restricted by different factors such as rainfall, terrain etc., the cultivated land intensive use of spatial characteristics is significant in Gansu province. There is more outstanding in the west and east of Yellow River. In 2008, for example the highest intensive degree city is Jiayuguan, it's up to 0.12. The lowest intensive degree city is Gannan, it's only 0.05; (3) Through the factor analysis, there are three major types of the driving forces of cultivated land intensive use in Gansu province: social economic factors, farming conditions and natural factors. Through the research，we found that the cultivated land intensive use of Gansu province mainly affected by the population, the scientific and technological level of policy and system, economic development, natural disasters restrictions. Relevant departments should from the above five aspects improve the level of cultivated land intensive use of Gansu province.
