Abstract：Due to the interference of human activities and the change of environment,the area of oyster reef in China keeps shrinking,which seriously affects the stability of marine ecosystem.To re-store oyster reef,440 mu of oyster reef was first established by oyster shell material in June 2021 in the intertidal zone of Yellow River Delta.Four months later,the development of oyster reef was investiga-ted and analyzed.The results showed that the sinking depth of oyster reef varied between 15 and 20 cm,but the height of the whole oyster reef was above 1m;and the average oyster density on oyster reef was 0.216±0.128 ind/cm2.The amount of oyster on the oyster shell was distinctly higher than that in bamboo rod and polyethylene rope.These results indicated that oyster shells are suitable for the attach-ment of oyster,and the reef based on oyster shells is suitable for oyster reef restoration in the intertidal zone of Yellow River Delta.
