肥城市土地利用生态安全评价与利用调控研究

Study on Land Ecological Security Evaluation and Land Utilizaton and Optimization in Feicheng City

摘要:

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。

Abstract:

On the basis of summarizing domestic and foreign related research, taking Feicheng city as an example, 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 landscape pattern. Combining with PSR framework model which is widely used in current ecological security evaluation, 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 index weights have been determined by using AHP method, and land ecological security situation in the region have been evaluated and analyzed. Finally, according to the results of evaluation, countermeasures for optimizing land utilization have been put forward.
