在总结国内外相关研究成果的基础上，以肥城市为例，采用 RS 和 GIS 技术对研究区地形地貌、植被覆盖、地质灾害、土地利用景观格局等土地生态安全影响因子进行提取和分析，同时结合当前在生态安全评价中广泛使用的 PSR 框架模型，分别从压力、状态、响应三方面选取18个对土地生态安全影响密切的因子构建土地生态安全评价指标体系，采用层次分析法确定各指标权重，对该地区土地生态安全状况进行评价和分析。最后，提出土地利用优化调控措施。

On the basis of summarizing domestic and foreign related research,taking Feicheng city as an ex-ample,by using RS and GIS technologies,some factors which will affect land ecological security have been extracted and analyzed,such as topography,landform,vegetation coverage,geological disasters and land-scape pattern.Combining with PSR framework model which is widely used in current ecological security e-valuation,selecting 18 factors respectively which has close relation with land ecological safety from the pressure,state and response,evaluation index system of land ecological security has been set up.The in-dex weights have been determined by using AHP method,and land ecological security situation in the re-gion have been evaluated and analyzed.Finally,according to the results of evaluation,countermeasures for optimizing land utilization have been put forward.
