近海海水养殖海域海底地下水排放的研究进展

Submarine Groundwater Discharge（SGD），a natural phenomenon in estuarine，coastal and offshore regions，is an important conduit for terrestrial materials input to the sea，and plays a dominant role in coastal biogeochemical cycles and environmental effects. With the rapid development of marine aquaculture in recent years，the relevant studies of the impacts of SGD on mariculture species are described，and the importance of SGD on different marine aquaculture ecosystems is illustrated. Firstly，the results of the bibliometric analysis show that the published literatures on the relationships between SGD and mariculture have significantly increased in the last 25 years，and it has been distributed with broad space and prospect worldwide. Through the summarized study cases，it was found that SGD and the associated nutrient substance can modify hydrological condition and can enhance the primary productivity in coastal waters，and then promote the growth of mariculture species such as macroalgae，fish and shellfish，showing positive impacts of SGD on mariculture. However，SGD was also suggested to have negative impact on mariculture species by reducing the production and even driving them to death. Meanwhile，the coastal mariculture was thought to affect SGD process and the associated materials from land to the sea. Therefore，with respect to the riverine input，although SGD is generally hidden，its-derived nutrient substances have been shown to play an increasingly important role in mariculture regions. More attention and robust research should be given to SGD and the associated materials in mariculture ecosystems，in order to make better use of SGD for sustainable development of marine aquaculture，which can provide scientific support for fishery rational arrangements and ecosystem managements of marine aquaculture in China.
