摘要: 了解种间关联性对正确认识生物群落结构和功能等具有重要意义。本文根据2013—2017年海州湾及其邻近水域渔业资源底拖网调查所获得数据,应用χ2检验、Jaccard指数和Spearman秩相关系数等方法研究了海州湾15种主要鱼类的种间关联性。χ2检验、Jaccard指数与Spearman秩相关分析结果一致,不同年份间正相关物种对所占比例较高,但显著或极显著正相关物种对数量较少,不同年份Jaccard指数检验显著或极显著关联物种对数分别有9、6、7、1、0;Spearman秩相关检验显著或极显著相关的物种对数分别为12、20、13、5、6。关联物种对存在一定的年际变化,但显著关联物种对年际间比较稳定,表明海州湾主要鱼类群落具有比较稳定的种间关联性。相同生态类型的种类在生态位上可以相互替代,与其他物种形成相互关联。

Abstract: It is important to reveal the interspecific association and correlation of main species for deep understanding of fish community structure and function. Based on data collected from the bottom trawl surveys from 2013 to 2017 in the Haizhou Bay and the adjacent waters, we analyzed interspecific association of main species using Chi-square test, Jaccard index, and Spearman rank correlation coefficient. There were consistent results from χ2-test, Jaccard index, and Spearman’s rank correlation analysis. The proportion of positively correlated species pairs was high in different years, whereas the number of significant or extremely significant species pairs was low. There were 9, 6, 7, 1, 0 significant or extremely significant species pairs over different years based on Jaccard index. There were 12, 20, 13, 5, 6 significant or extremely significant species pairs over different years based on Spearman’s rank correlation coefficient. While there were inter-annual changes in related species pairs, the relationship between significant species pairs was relatively stable, indicating a relatively stable interspecific association in the main fish communities. The species within the same ecological type could replace each other in the niche, which have adapted to environmental changes in Haizhou Bay and its adjacent waters.
