在参考国内外对土地资源生态环境安全研究成果的基础上,以甘肃省为例,基于压力-状态-响应（Pressure-State-Response,简称PSR）结构模型,构建了一套包括22个指标变量的土地生态安全评估指标体系。运用熵值法确定指标权重,采用综合指数评价法计算了甘肃省2005—2013年的综合生态安全值并对结果进行分析。结果表明：总体来看,甘肃省土地生态环境安全状况逐渐改善,但还处于＂一般＂状态。

Based on the reference on the basis of land resources ecological security at home and abroad, taking Gansu province as an example, and based on the Pressure-State-Response （PSR） structure model, a set of 22 indicators variables in evaluation of land ecological security index system was constructed. Using entropy method for determining attribute weights, comprehensive index evaluation method was used to calculate the integrated values of ecological security 2005-2013 in Gansu province and to analyze the results. The results show that the overall land ecological environment security situation of Gansu province continues to improve, but it is still in the ＂general＂ condition.
