摘要
渔业资源可持续利用是涉及经济、社会、资源环境等各方面的综合性问题。本文以灰色系统理论为基础,提出了渔业资源可持续利用综合评价方法和步骤。该方法具有比传统的生物-经济模型更为全面,它可量化地反映渔业资源可持续利用的各个方面。本文以1978-1990年东海区渔业资源的发展状况作为实证分析,结果表明;1978年以后,东海区渔业资源可持续利用水平基本上呈现下降的趋势,1983-1986年处在较低的水平,1987年后可持续利用水平有所上升。
Sustainable use of fisheries resources is a comprehensive subject related to economy, society, resources and environment. The paper primary puts forward the general ways on the synthesis assessment of sustainable use of fisheries resources based on grey theory. The way possess the advantages over the traditional bio-economic models since it fully reflects the system of sustainable use of fisheries resources. The paper takes the fisheries resources in East China Sea from 1978 to 1990 as an example. The results indicate that the level of sustainable use of fisheries resources in East China Sea generally falls, the value from 1983 to 1986 droped into the lower level, the value after 1987 improves slowly.
