Abstract: An Ecopath model of artificial reef ecosystem was established in the Zhangzi Island by the software known as Ecopath with Ecosim（EwE）6.4 and the energy flow pattern and the system attributes were evaluated in the ecosystem in summer from 2010 to 2012 in order to investigate the structure and function of Zhangzi Island arti- ficial reef ecosystem. The model was found to be comprised of 23 functional groups, including the main processes of the energy flow in the artificial reef ecosystem in Zhangzi Island. The results showed that yesso scallop Patinopecten yessoensis, Schlegel＇s rockfish Sebastes schlegelii, fat greenling Hexagrammos otakii and other marine organisms had higher trophic level value from summer in 2010 to smnmer in 2012. The prey overlap index was found to be in- creased from O. 123 to 0. 139 in disk abalone Haliotis discus hannai and the prey overlap index from 0.112 to 0. 165 in disk abalone Haliotis discus hannai. The predator overlap index was increased from 0. 063 to 0. 185 in Schlegel＇s rockfish and from 0. 062 to 0. 132 in fat greenling. The ecological efficiency（EE） index was increased from 11.1% in summer of 2010 to 14.4% in summer of 2012, with finn＇s cycling index （FCI） of over 0.1 and high net system production （NSP）. The system omnivory index （SOI） was increased from 0. 136 to 0. 172, the connectance index （CI） from 0. 203 to 0. 224, and Finn＇s mean path length （MPL） from 2. 555 to 3. 486 in Zhangzi Island artificial reef ecosystem in summer from 2010 to 2012. In conclusion,the Zhangzi Island artificial reef ecosystem was tound to be in stable mature stage from 2010 to 2012.
