| 摘 要： | 根据3艘舟山灯光围网渔船的生产统计数据,通过层次 分析法(AHP),分析了影响渔船捕捞能力的因子(总吨位、主机功率、作业天数和水下灯功率),并根据各影响因子的重要性确定其权重,建立影响灯光围网渔船捕捞能力的多因子评价模式。结果表明:总吨位对灯光围网捕捞能力的影响最甚,其次是主机功率、作业天数和水下灯功率,其所占权重分别为0. 461 2,0.342 4,0.137 1和0.059 4。

| Abstract: | Based on the production of 3 fishing vessels, the weight of factors including gross tonnage, power of the main engine, operating days and underwater light power that affect the catching capability of light-purse seine vessels in Zhoushan waters were analyzed with AHP and the weights of the factors were defined according to their importance and evaluation model of factors affecting catching capability of light-purse seine vessels was established. The results show that the weight score for gross tonnage,power of the main engine, operating days and the underwater light power is 0.461 2, 0.342 4, 0. 1371 and 0.0594 respectively. |
