[Construction and evaluation of indicator system for sustainable use of fishery resources in Zhoushan fishing ground].
In order to assess the sustainable use level of fisheries resources, Zhoushan Fishing Ground was selected as a demonstration. Based on 24 indicators related to the resource-environment 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.
