摘 要：
以兰州市市区土地利用状况作为研究对象,结合该区所处发展阶段及土地利用现状特点构建评价指标体系。运用数据包络分析(DEA)方法中的C2 R模型对该区1997—2008年城市土地利用经济效益进行定量分析和评价。结果表明,兰州市土地利用经济效益水平较高,但DEA无效年份土地投入冗余,且产出不足。结合兰州市的土地利用实际情况,从加大土地集约利用力度,盘活低效率用地,调整产业结构和注重人地协调4个方面提出提高兰州市城市土地利用经济效率的建议。

摘 要：
The land use status of Lanzhou City was investigated,and an evaluating indicator system was constructed by combining the economic development and the land use characteristics of the city.The C2R model and data envelopment analysis(DEA) approach were used to quantitatively analyze and evaluate land utilization economic benefit of the city from 1997 to 2008.The results show that the land utilization of Lanzhou City had high economic benefit level.However,in non-DEA efficient years,the land input was sufficient while the land output was not.Lastly,four suggestions were proposed to improve the economic benefit,including promoting intensive land use,improving low efficiency land,adjusting the industrial structure and paying more attention to the coordination of man-nature relationship.
