提升土地利用效率是缓解建设用地需求与经济增长压力间矛盾的必然途径，也是构建和谐人地关系与走可持续发展道路的重战略。在构建城市群土地利用的综合指标体系的基础上，运用数据包络模型测算了2000年、2006年和2011年的城市群土地利用效率，剖析了区域差异、时空变化特征及影响因素。研究表明，中国城市群土地利用效率相对偏低，区域间的效率差异较大，中西部地区的土地利用综合效率相对较低；城市群土地素投入的非集约值大、非集约度高，与综合效率呈现显著的负相关关系。

The ascent of the land use efficiency is an inevitable way to ease the contradiction between the shortage of construction land and the grim economic growth pressure, which is also important strategy to promote environmental health and sustainable development. This essay analyzes the space - time e- volution trends of the land use efficiency of urban agglomera- tions. It selects the key input- output items respectively and builds land use efficiency measurement system. Furthermore, this essay uses DEA model to determine the temporal - spatial and distribution patterns of land use efficiency. The results show that the efficiency experiences a slow growth process, and the difference is obvious. Comprehensive efficiency of urban agglom- erations in central and western regions is lower than those in the eastern region. The spatial variation of land intensive utilization is significant, which is negatively related with comprehensive efficiency.
