Abstract: Comprehensive evaluation of ecological restoration effects belongs to the post-evaluation of an artificial reefs construction project, and is one of the hotspots and difficulties in artificial reefs researches. Based on the pressure-state-response (PSR) conceptual model, this paper constructs an evaluation index system of artificial reefs ecological restoration effect from the basic situation of marine ecological environment and ecosystem structure in the demonstration area and the control area. In order to reduce the information redundancy caused by the correlation between the indicators and the influence of the weight assignment on the evaluation result, this paper introduces Choquet fuzzy integral to construct a comprehensive evaluation model, and uses the data of the artificial reef area of Qinhuangdao in May 2012 as an example to carry out the evaluation. The result shows that the artificial reef has a certain ecological restoration effect.
