摘 要: | 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。

Abstract: | Based on the reference on the basis of land resources ecological security at home and a-broad,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 evalu-ation 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 se-curity situation of Gansu province continues to improve,but it is still in the “general”condition. |
