辽宁省海洋渔具渔法结构调整的研究

根据辽宁省海洋捕捞产量的统计资料，运用灰色关联法分析了拖网、围网、流刺网、钓具、定置网5种主要渔具渔法的产量与海洋捕捞总产量的关联度，运用改进的层次分析法确定了5种主要渔具渔法产量的权重。结果表明，海洋捕捞产量与定置网、拖网的产量的关联度高，与围网、钓具和流刺网的产量关联度低；拖网、围网、流刺网、钓具、定置网产量的计算权重分别约为23．3％、16．1％、31．1％、20．4％、9．1％。对辽宁省渔具渔法产量结构调整进行了讨论。

The study on the structure regulation of marine fishing gears and methods in Liaoning province

Based on marine fishing yields statistics data in Liaoning province, an analysis of the correlativity between all marine fishing yields and each main fishing gear (trawl, seine, gill net, hook and fixed net) yield was made by grey association analytic process. The improved analytic hierarchy process (AHP) was used to calculate the percentage of five kinds of main fishing gears in Liaoning province. The result indicated that the correlativity was higher between marine fishing yield and the yields of fixed net and trawl, but was lower between marine fishing yield and the yields of seine, hook and gill net. The calculated percentage of five kinds of fishing gears, which included trawl, seine, gill net, hook and fixed net, were 23.3%, 16.1%, 31.1%, 20.4% and 9.1% respectively. And a discussion about the structure regulation of marine fishing gears was made.
