摘　　要：为了深入探究海州湾及其邻近海域鱼类群落功能冗余,更好地理解群落稳定性,本研究基于2013—2023年该海域鱼类资源春、秋两季调查数据,应用功能冗余指数和相关性分析等方法研究了该海域鱼类群落功能冗余的时空变化及影响因素。结果表明:该海域2013—2023年秋季功能冗余指数均值为9.39,春季为8.62,秋季的鱼类群落较春季稳定,其中,2015、2016、2018和2023年的功能冗余指数存在显著的季节差异,其余年份两季节间差异不显著。鱼类群落功能冗余指数呈现出一定的年际波动且该波动在秋季更为显著;在秋季,2021年的功能冗余指数最高,为10.36,2020年最低,为8.61;在春季,2022年最高,为9.64,2018年最低,为7.96。春季的功能冗余指数在大多年份呈现由北向南增加的趋势,且多在20 m以浅水域值较高,而秋季大多年份呈现由西南向东北方向降低的趋势。鱼类群落功能冗余的时空变化与鱼类生物量、种类数以及水温、盐度和水深等环境因素变化有关,功能冗余指数与鱼类生物量、种类数和水温大多呈正相关关系,而与盐度和水深呈负相关关系。To explore the functional redundancy and better understand the stability of fish community in the Haizhou Bay and its adjacent waters,we examined the temporal and spatial variations in functional redundancy of fish community and the influencing factors using functional redundancy index(FR)and correlation analysis based on fish resource survey data in spring and autumn from 2013 to 2023.The results showed that the average value of FR was 9.39 in autumn and was 8.62 in spring.Fish community was more stable in autumn than in spring.There were significant seasonal differences in FR in 2015,2016,2018,and 2023.The FR of fish community showed interannual fluctuation,which was more significant in autumn.In autumn,the highest FR(10.36)was found in 2021,while the lowest value(8.61)was found in 2020.In spring,the highest value(9.64)was presented in 2022,and the lowest value(7.96)was in 2018.The FR increased from north to south in spring in most years,and the values were generally higher in the shallow waters less than 20 m in depth,but decreased from the southwest to northeast in most years in autumn.The spatio-temporal variations in functional redundancy may be related to fish biomass,number of species,and environmental factors such as water temperature,salinity and depth.The FR was positively correlated with fish biomass,number of fish species,and water temperature,but negatively correlated with salinity and depth.
