中文摘要：

通过构建PCA‐SFA模型，运用2003—2011年的相关数据，测度安徽省城市新区建设过程中土地利用效率。结果显示：在不考虑环境因素的情况下，2003—2011年间安徽省城市新区建设土地平均利用效率为0.9139，说明土地整体利用效率较高；从城市新区建设土地利用效率的动态变化来看，2003—2007年间提升速度较快，而2009—2011较为平缓。在PCA‐SFA模型中加入环境因素后，安徽省城市新区建设土地利用效率小于不考虑环境因素时的测度值，说明各城市在新城区建设过程中，对环境造成了一定的破坏，降低了土地利用效率。但二者之间的差距呈现出缩小的趋势，说明安徽城市新区建设过程中，环境保护力度正在逐渐加大。

英文摘要：

By constructing PCA‐SFA model ,using data of 2003 -2011 ,the efficiency of urban new district land utilization of Anhui is measured . Results show that without considering environmental factors ,the average land utilization efficiency of urban new district is 0 .913 9 during 2003-2011 ,w hich suggests that the overall land utilization efficiency is rather high ;dynamic changes of it grew faster from 2003 to 2007 ,while that from 2009 to 2011 grew more gently ;after considering the environmental factors ,the efficiency in Anhui is less than before . It shows land as inputs promoting economic development has caused some damage to the environment in the course of city new district construction in Anhui .But the narrowing trend of the gap show s city new district construction has intensified the efforts on the environmental protection .
