摘要
由于潮滩组成要素不稳定、地理区位特殊以及人为因素的制约,导致潮滩极易受外在和内在因素的影响,发生自然系统脆弱性(包括固有脆弱性和特殊脆弱性)。在总结国内外关于潮滩脆弱性评估方法(诸如综合指数法、层次分析法等综合评估方法以及主成分分析法、高程面积法等单一影响评价法)基础上,根据潮滩脆弱性评估的选择原则,构建了潮滩脆弱性评估指标体系,以期为沿海地区的可持续发展提供理论和技术支撑。
Because of the instability of tidal lfats, the particularity of their geographical location, and human inlfuences, tidal lfats are vulnerable to various external and internal factors, which lead to both intrinsic and speciifc vulnerability. This paper reviews the methods for assessing the vulnerability of tidal lfats in both China and other countries, including comprehensive assessment methods such as the comprehensive index method, the AHP （Analytic Hierarchy Process） method, and single-impact assessment methods such as principal component analysis and the elevation and area method. On the basis of the review, an index system of tidal-lfat vulnerability assessment is constructed that should provide theoretical and technical support for sustainable development in coastal areas.
