摘要
基于EES模型,从经济、环境、社会三个方面构建了土地生态安全评价体系,以连云港为例运用集对分析法对研究期内的土地生态安全进行诊断研究,结果显示,连云港在研究期内的土地生态安全等级由"不安全"升至"较安全",整体安全水平趋势变好,但"较安全"的联系度趋于区间下限,土地生态安全状况形势依然严峻.
Based on EES model in this article,land ecological security evaluation is constructed from three aspects of economic,environmental,and social system,in Lianyungang for example,set pair analysis method is used to study the period of land ecological safety,the results showed that Lianyungang during the study period of land ecological security level by"unsafe" to "safer",overall safety level trend is getting better,but "safer"connection degree range,land ecological security situation is still grim situation.
