摘要： The oyster reef restoration has raised concerns worldwide due to the advantage of alleviating eutrophication and other ecosystem services. The necessary prerequisite for oyster restoration is identifying suitable sites. A resto-ration suitability index model for C. gigas reefs was built by combining the Monte Carlo simulation, analytic hierarchy process, hydrodynamic modelling and geographic information systems and applied in Laizhou Bay (LZB), China. The model outputs and sensitivity analysis showed that the east coastal area, the southern part, and the western part of LZB were restoration sites with the maximum suitability, accounting for 15.3 % of LZB. The middle and northern parts of LZB were unsuitable sites restricted by water depth and flow velocity. Ship wa-terways and marine industries were the major factors causing degradation of the historically recorded oyster reefs. This model can support oyster restoration planning, and can be applied to other oyster species with adjusted indicator system.
