摘　　要：沿海地区生态环境恶化与不合理的区域开发有关。以驱动力-压力-状态-影响-响应(D-P-S-I-R)为框架,构建指标体系;基于突变理论,应用方法处理数据,选择生态环境问题较突出的大连市为例,识别其自2005年至2012年的生态安全综合指数值,为大连及其他沿海地区的经济与环境保护协调发展,实现生态安全提供借鉴和参考。Environmental degradation can not be separated from the sustainable regional develop-ment in coastal areas. This paper, firstly, tries to set up an indicator system for ecological secur-ity assessment using DPSIR framework;secondly, it utilizes dimensionless to process data, tak-ing Dalian city which is beset with serious environmental problems as an example for the analysis of its ecological security status based on catastrophe theory. The result reveals that the most dan-gerous year is 2005 , the relatively safe years are 2008 , 2010 and 2011 , while the critical years are 2007,2009 and 2012 respectively. Lastly, it provides references for Dalian city and other coastal areas to realize the coordinated development of economy and environment and ecological security management.
