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
