摘      要：Abundance and distribution of jumbo flying squid(Dosidicus gigas)are evidently influenced by the changes of marine *** this study,the maximum entropy(MaxEnt)model was applied to examine the impacts of marine environmental variables on its potential distribution,and identified habitat hotspots of *** in summer and autumn along the coast of *** MaxEnt model was constructed by using the fisheries data of *** from summer to autumn during 2011–2017 combined with critical environmental factors including mixed layer depth(MLD),sea surface salinity(SSS),sea surface height(SSH)and water temperature at depths of 0 m,25 m,50 m,100 m,150 m,200 m,300 m,400 m and 500 *** showed that the actual fishing efforts of *** in summer and autumn were mostly distributed in the suitable habitat,indicating that the MaxEnt model can well predict the habitat hotspots of *** off *** key environmental factors and their suitable ranges for *** showed significant intermonthly changes from December to *** critical environmental factors of *** off Chile were MLD,SSH,water temperature at different depths in summer(Temp_25 m in December,Temp_300 m in January and Temp_400 m in February)and SSH,SSS,Temp_400 m in *** findings suggest that selecting the key environmental factors is vital to study the potential distribution of *** off Chile in each month to explore its habitat hotspots.
