基于AHP-熵权法的海岛海岸带脆弱性评价指标权重综合确定方法

Comprehensive method for determining the weights of vulnerability assessment indexes on islands and the coastal zone based on the AHP weight method and entropy weight method

海岛海岸带脆弱性评价过程在模型构建、指标筛选、权重确定以及数据获取和同化等方面存在技术难点。其中,脆弱性评价指标权重确定是关系评价结果科学性、合理性的重要一环,应尽快开展相关研究。基于计量数学方法,借鉴以往脆弱性评价研究的经验教训,根据主观与客观赋权法的特点,运用AHP法与熵权法提出较以前主客观赋权研究更为科学、合理的赋权方法,并通过黄河三角洲海岸带脆弱性进行应用示范。结果表明,该评价指标权重确定方法具有一定实用意义。

In terms of islands and coastal vulnerability assessment process, there are technical difficulties in building the model, indexes screening, weight determination and data acquisition and assimilation. Among them, determining the weights of vulnerability assessment indexes is an important part during the evaluation process, so related research should be carried out as soon as possible. Based on mathematical method and the previous studies, according to the characteristics of the subjective and objective weight method, applying the AHP weight method and entropy weight method, a new method which is more scientific and reasonable than previous subjective and objective empowerment studies is put forward. And finally, according to the method, to determinate the weight of partial vulnerability evalua- tion indexes shows the effectiveness and practicability of the method.
