摘要: 以舟山渔场为例,选择了渔业资源环境、社会和经济3个子系统的24个指标,对各子系统的指标体系进行了主成分分析.在此基础上采用灰关联度分析,计算了舟山渔场1954~1990年的相对关联度,以此作为评价舟山渔场渔业资源可持续利用的指标,对舟山渔场的渔业资源可持续利用水平进行了评价.结果表明,1962年前舟山渔场渔业资源的可持续利用水平较低;1962年后可持续利用水平不断上升,在1974达到最高,相对关联度比1962年增加44.78%;1978年后可持续利用水平持续下降,1983年降至最低水平,只有1974年的51.72%.

Abstract: In order to assess the sustainable use level of fisheries resources,Zhoushan Fishing Ground was selected as a demonstration. Based on24 indicators related to the resource environment subsystem,social subsystem and economic subsystem,principal component analysis was employed to analyze the indicator system in each subsystem,and grey relative relationship analysis was computed as a indicator to evaluate the sustainable use level of fisheries resources. The results indicated that the sustainable use of fisheries resources was at a lower level before 1962,and gradually rose to the top in 1974. It has sharply declined since 1978,and dropped to almost the lowest level in 1983,being 51.72 % of 1974.

Key words: Fisheries resources, Sustainable use, Grey relative relationship, Zhoushan fishing ground, Indicator system
