摘要： 为了给土地资源的可持续利用提供决策依据，基于土地利用效益及其协调度，建立了评价体系，运用熵值法对玉门市2002—2012年的土地资源可持续利用进行了综合评价。结果显示：（1）研究期内土地利用综合效益从2002年的55.74增加到2012年的88.89，总体呈逐年增加的趋势，土地利用的状态由可持续利用的起步阶段升级到基本可持续利用阶段；（2）土地利用各效益的协调度值从0.68降为0.20，协调度由比较协调状态变化为不协调状态。研究期内土地利用的总体状态是良好的，但在社会经济发展过程中片面追求经济效益而损害了土地利用的生态效益和社会效益，玉门市单纯追求经济发展而忽略生态效益的发展方式在土地利用中越来越突出。

Abstract: In order to provide decision making basis for the sustainable use of land resources, we established evaluation system based on efficiency of land use and coordinated degree. Entropy value method was used to carry out the comprehensive evaluation on the sustainable utilization of land resources in Yumen City from 2002 to 2012. The results indicated that: (1) integrated benefits of land use increased from 55.74 in 2002 to 88.89 in 2012, representing an overall increase trend year by year, and the status of land use changed from starting to the basic stage of sustainable utilization; (2) coordination degree of land use benefit decreased from 0.68 to 0.20, changing from relatively coordinated stage to uncoordinated stage. It was concluded that the overall status of land use turned to be good during the study period, but the one-sided pursuit of economic benefit in the process of social and economic development damaged the ecological and social benefits of land use. Simply pursuit of economic development without taking ecological benefits into consideration in land use was more and more obvious in Yumen City.
