| 摘 要： | 随着社会经济的高速发展,生态安全问题越来越重要,它已经成为区域可持续发展的核心问题。以辽宁省的14个城市为研究区域,采用压力-状态-响应模型,选取了26个指标,运用层次分析法（AHP）和熵值法对其生态安全现状进行评价,结果表明：各个城市生态安全值位于0.31~0.8,生态安全水平差异较大。总体来说,沿海地区城市群生态安全较好,中部省会城市群生态安全次之,西部的朝阳、阜新等小城市生态安全较差。最后提出了辽宁省城市生态安全的对策。

| Abstract: | With rapid development of economy and society,the problems on ecological safety become more and more important.They have been key problems of regional sustainable development.By using analytical hierarchy process(AHP) and the entropy method and building an assessment index system including 26 targets based on P-S-R pattern,the paper assessed the ecological safety in 14 cities of Liaoning province.The results showed that the eco-safety index of each of the above mentioned cities was found to be between 0.31 ... |
