摘　　要：为探究环境因子对智利竹筴鱼资源丰度的影响,根据2012—2018年4—8月中国东南太平洋智利竹筴鱼(Trachurus murphyi)渔捞日志数据,基于不同环境因子(海面温度、叶绿素a浓度、海面温度异常值和海面高度异常值)组合建立5个环境剩余产量(EDSP)模型。结果表明:海面温度对智利竹筴鱼单位捕捞努力量渔获量影响最大,其次为海面温度异常值和叶绿素a浓度,海面高度异常影响相对较小;基于海面温度、叶绿素a浓度、海面温度异常值和海面高度异常值的剩余产量模型拟合程度最好,表达式为C_(n)=1.74912E_(n)-0.00013E_(n)^(2)+0.00350T_(n)E_(n)-1.97876A_(n)E_(n)-2.75530H_(n)E_(n)+0.24674S_(n)E_(n);捕捞努力量、海洋环境因子海面温度、叶绿素a浓度、海面温度异常值和海面高度异常值均不同程度地影响智利竹筴鱼资源丰度的变动。In order to simulate the relationship between the fishing ground distribution and environmental factors,based on the fishery data of Chilean jack mackerel(Trachurus murphyi)in the Southeast Pacific Ocean from April to August,2012 to 2018,5 environmentally dependent surplus production(EDSP)models were constructed based on different combination of the sea surface temperature(SST),chlorophyll a concentration(Chl-a),sea surface height anomaly(SSHA)temperature anomaly(SSTA).The results indicated that the surplus production model based on the environmental factors SST,Chl-a,SSTA and SSHA was the best,which could be expressed as C_(n)=1.74912E_(n)-0.00013E_(n)^(2)+0.00350T_(n)E_(n)-1.97876A_(n)E_(n)-2.75530H_(n)E_(n)+0.24674S_(n)E_(n).Variation of Chilean jack mackerel biomass was controlled mainly by fishing effort,SST,Chl-a,SSTA and SSHA in the fishing ground.
