摘　　要：运用C-D生产函数理论,结合投入产出原理,构建保定市耕地集约评价的数学模型,对保定市2003—2012年间耕地利用的投入产出情况进行分析,进而对保定市耕地利用集约度的变化特征进行年际间和空间上的比较研究。研究结果表明:10年间保定市耕地利用中劳动集约度较高,资金粗放度较高,综合集约度呈现波动式发展;从空间上看,保定市各县(市)呈现出东部集约程度高、西部集约度相对低的空间分布特征,空间相关性较明显。Applying the C-D production function theory, combining the theory of input and output, an evaluation mathematical model was established on the intensive use of the cultivated land of Baoding city from 2002 to 2012, and the input and output situation in the process of cultivated land use was analyzed. The variation characteristics of the cultivated land use intensity of Baoding city has carried on the comparative study between the annual and the space. The results showed that ： the labor intensity of Baoding cultivated land is the highest use during 10 years, capital extensive degree is higher, and comprehensive intensive degree fluctuated; with spatial distribution of a higher intensity in eastern area and relatively low intensity in western regions, and the spatial correlation is more obvious.
