基于模糊等价关系的聚类分析方法在鱼类种群鉴定和海洋强风暴潮灾害评估中的应用研究

摘要

Fuzzy cluster analysis based on fuzzy equivalence relation was used for modeling the identification of fish stocks and the assessment of marine severe storm tide disaster. Empirical analyses were conducted by the fuzzy clustering model using 2 340 data sets of grass carp stocks from the Yangtze River, the Pearl River, and their hybrid offspring, and data sets of 13 severe storm tide disasters that damaged Shanghai from 1981 to 2000, respectively; the results indicated that the method is practical and effective.%利用基于等价关系的模糊聚类分析方法，在鱼类形态种群鉴别和强风暴潮灾害评估方面进行建模分析。选取长江、珠江草鱼及其杂交组合的后代共2340个数据，以及1981-2000年以来对上海造成灾害的13场强风暴潮过程及灾害资料数据，利用模糊聚类模型分别进行试验和数据实证分析，结果表明该方法是实用及有效的。
