In light of the recent study of bioturbation in the coast areas of Jiangsu-Zhejiang, it has been shown that the burrow forms of benthos are related to water depths. Most of shallow benthos tend to live in various vertical burrows in order to avoid or reduce the influences of changeable environmental variables. The intensity of bioturbation is obviously different and closely related to the rates of sedimentation. In general, the lower the rate of sedimentation the more intensive the bioturbation.In addition, the bioturbation can affect directly the microchemical environment near the interface between water and sediment and even changes the extension of oxidation zone within sediments. Perhaps, it not only influences the determination of ancient redox environment, but also shows indirectly some critical environmental factors.
