摘　　要：柔鱼是我国远洋渔业重要的经济对象之一,实现柔鱼资源可持续利用是研究的重要内容。本研究以Gordon-Schaefer生物经济模型为基础,根据1995—2019年北太平洋柔鱼生产作业数据及相关经济数据,构建生态效益、经济效益和社会效益相结合的综合优化配置模型,分析燃油成本变动对柔鱼资源可持续利用的影响,模拟9种不同方案下燃油成本的变动对于北太平洋柔鱼短期(1—5年)、中期(10年)和长期(20年)的累计资源量、累计渔获量以及累计经济利润变动的影响。结果表明,方案6(燃油成本降低2.5%)和方案7(燃油成本降低5%)既能够获得可观的渔业利润,又可以兼顾柔鱼资源量,使其免受过度捕捞,综合考虑生物、经济、社会和生态等方面因素的影响,可作为实现柔鱼资源优化配置的最适方案。Ommastrephes bartramii is an important economic species of the pelagic fishery of China,and the sustainable use of fish resources is an important part of the research.In this study,basing on the Gordon-Schaefer bioeconomy model,the bio-economic social synthesis was established by considering the impact of biology,economy and society.We used the production and related economic data of the north Pacific Ocean from 1995 to 2019 to analyze the impact of the change in fuel cost on the sustainable use of fish resources.Up to 9 fishing scenarios were drawn to simulate the accumulative stock biomass variation,accumulative catch and accumulative profit changes under different scenarios of fuel cost for short-term(1-5 years),medium-term(10 years)and long-term(20 years)resources.The results showed that both scenarios 6(2.5%reduction in fuel cost)and scenarios 7(5%reduction in fuel cost)obtained not only considerable fishery profits but also protected soft fish resources from overfishing.Considering the influence of biological,economic,social and ecological factors,they can be used as the optimal scenarios to realize the optimal allocation of resources.
