摘要： 海洋灾害造成贝类养殖损失的价值评估是海洋科学与水产科学交叉产生的新科学命题,同时也是渔业经济学与保险价值核算的难题。本文从海浪导致贻贝脱落致灾的角度展开研究,采用第三代海浪模型SWAN,以嵊泗海域作为研究区,通过P-Ⅲ曲线拟合、波高重现期分析,定量研究了台风期间贻贝脱落率与有效波高之间的相关性。研究表明,当有效波高达到3 m时,贻贝开始出现脱落的可能性较大;当有效波高超过9 m时,出现脱落率达100%的可能性较大。研究结果可作为海洋水产养殖损失保险理赔的参考。

关键词: 贻贝, SWAN, 有效波高重现期, 脱落率

Abstract: The evaluation of mussel loss rate caused by marine disasters is a new scientific proposition produced by the intersection of marine science and fishery science. At the same time, it is also a difficult problem in fishery economics and insurance value accounting. The effect of sea wave disaster on mussel loss rate was studied in this research, adopting the third generation wave model SWAN to calculate the significant wave height. The significant wave height with different return periods around Shengsi sea area was calculated, and the relationship between mussel loss rate and significant wave height in Shengsi sea area was analyzed. The results show that when the effective wave height is up to 3 meters, mussel begin to fall off; when the effective wave height is bigger than 9 meters, the probability of mussel loss rate reaching 100% is high.

Key words: mussel, SWAN, significant wave height return period, loss rate
