基于灰色关联和聚类分析的南极渔业资源利用评价
Evaluation of Antarctic fishery resource utilization based on grey correlation and clustering analysis
摘要
Abstract
In view of the ecological importance of Antarctic fishery resources,the special nature of its management,the involvement of multiple rights and interests,the study on the utilization of Antarctic fishery resources is currently not abundant.Scholars in different fields may have different understandings of the same issue,which is not conducive to the interdisciplinary integration of Antarctic governance issues.Based on the most recent fisheries data(1969-2021)publicly available from the Commission for the Conservation of Antarctic Marine Living Resources(CCAMLR),ten representative target species were indexed by grey correlation analysis,and the Antarctic fishery resource utilization of 26 subjects(fishery nations)were evaluated longitudinally.Based on this,combined with other indicators reflecting the status of Antarctic fishery,the fishery nations were clustered and the homogeneity and differences of Antarctic fishery resource utilization in different nations were explored from a horizontal perspective.Finally,combining with the utilization pattern of Antarctic fishery resources and the development status of Chinese krill fishery,the Chinese consideration was put forward in order to provide information for the scientific regulation of fishery resources and the protection of Chinese legal rights and interests in the Antarctica.The results show that the utilization of fishery resources in 26 nations can be roughly divided into two vertical gradients,the first gradient includes the Soviet Union,France,New Zealand and the next 10 nations with little difference in the correlation degree,while the remained 13 nations with the low correlation degree,including China,are classified as the second gradient.Horizontally,the Antarctic fisheries of various nations have their own uniqueness,but certain similarity also occurs.The clustering results indicate that 6 clusters are the optimal,which is consistent with the actual fishery situation.This study shows that the Antarctic fishery presents a multilateral development pattern with gradients and gaps.The resource utilization of some nations are diversified,while others are more specialized.China's Antarctic fishery is still in its initial stage and only krill fishery is developed,the diversity of resource utilization is at a low level.In the future,it is necessary to strengthen scientific research,deepen international cooperation,and realize diversified development integrating specialized and extensive observation to contribute more to the management of Antarctic resources.关键词
