摘要
Abstract
Based on the survey data of fishery resources and ecological environment in Zhangzi Island and adjacent waters during 2022-2023,a food web model of Zhangzi Island waters ecosystem was constructed by Ecopath soft-ware.Using Ecopath model,we analyzed the structure,the process of energy flow and ecosystem characteristics of the Zhangzi island waters.The results indicated that the Ecopath model of Zhangzi Island waters was composed of 31 functional groups,with the trophic level of each functional group ranged from 1.00～4.24.The energy flow of the system was mainly distributed among the five trophic levels,and the biomass and material flow between the trophic levels decreased with the increase of the trophic level,showing a typical pyramid distribution.Futhermore,the total system throughput(TST)in the ecosystem is 11 641.81 t/(km2·a),and the total transfer efficiency(TE)is 13.29%,which primary producers is 13.35%and the detritus is 13.21%.The ratio of total primary pro-duction to total respiration(TPP/TR)was 3.15,the system omnivorous index(SOI)was 0.19,and the connec-tivity index(CI)was 0.23.Through the study of Zhangzi Island waters ecosystem model,we suggest that the Zhangzi Island waters ecosystem is currently in the development stage.关键词
