| 摘 要： | 如何通过科学的指标体系和评价方法，对土地生态安全状况进行客观评价，对促进土地资源可持续利用具有重要意义。以山东省为研究区域，依据“驱动力—压力—状态—影响—响应”（DPSIR）概念框架模型，构建土地生态安全评价指标体系，建立土地生态安全的TOPSIS评价模型，对山东省的土地生态安全状况进行了评价。评价结果表明:山东省2006—2013年的土地生态安全状况总体上处于不断转好的趋势，但仍然不容乐观。并从维护土地资源生态安全及其可持续利用视角，提出具体对策。研究表明通过DPSIR建立土地生态安全评价指标体系，采用TOPSIS方法对土地生态安全评价是科学可行的。

| Abstract: | How to establish the appraisal index and adopt scientific method for the objective appraisal of land ecological security is important for maintaining sustainable land use. Taking the Shandong Province as example for the research, we adopted the conceptual model of ‘Driving forces-Pressure-State-Influence-Response’ to set up the land ecological appraisal index system. The TOPSIS model was used to the appraisal of land ecological security of Shandong Province. The appraisal results showed the land ecological kept improving during the period from 2006 to 2013. But it was not optimistic because it was still graded ‘Sensitive’. The countermeasures were put forward for maintaining land ecological security and land sustainability for Shandong Province. The research can prove that DPSIR model and TOPSIS method are scientific and feasible for the appraisal of land ecological security. |
