With further recession and deterioration of offshore fishery resources and increasing living demands,construction of marine ranching becomes a focal point to improve marine biological resources and environment,while artificial reef is one of the important parts for marine ranching construction. The artificial reef technology develops slowly in China compared with developed countries,such as the United States and Japan,and there are still many issues urgently to be solved.When an artificial reef is released in water,there are various kinds of forces,and its forces and flow field-effect are closely related to surrounding conditions and its own performance. Currently,there are no mature conclusions on research of hydrodynamics of artificial reef. According to review of hydrodynamics of artificial reefs,we hope to give a full understanding on hydrodynamics performance of artificial reefs,and provide reference and theoretical basis for further research on design and structure of artificial reef in China.
