摘要
海峡西岸的生态环境质量位居全国首列,但是,由于生态环境的脆弱性和生态环境的污染,以及海峡西岸的快速城市化发展,其生态安全面临着严峻的挑战。利用漏斗模型即压力-支撑-响应模式进行海峡西岸的生态安全评价,通过主成分的分析方法计算压力度指数、支撑度指数、响应度指数,最后根据漏斗模型对海峡西岸的生态安全度进行评价。结果表明:1)泉州市、福州市、厦门市、莆田市的生态安全度较高,而漳州市、三明市、宁德市的生态安全度较低;2)生态安全度并不仅仅由环境承载力决定,而且与经济社会发展程度有着较密切的相关关系,较高的生态安全度需要较强的经济基础作为支撑。
The ecological environmental quality of the Economic Zone in Western Coast of Taiwan Strait ranks the top of China, but the ecological security is facing serious challenges due to the vulnerability and contamination of ecological environment and the rapid urbanization. Based on the pressure-support-response model of ecological security assessment, the indices of pressure, support, and response were calculated by the method of principal component analysis, and then, the ecological security of the Western Coast was assessed. Among the cities in the Western Coast, Quanzhou, Fuzhou, Xiamen, and Putian had a higher ecological security index （ESI）, while Zhangzhou, Sanming, and Ningde ranked in lower place. The ESI was not only determined by environmental carrying capacity, but also closely related to the development degree of economy and society. A higher ESI needed stronger economic basis to support.
