Abstract

Dissolved inorganic carbon(DIC) in the waters of the Daya Bay was investigated to analyze its spatial distribution in May 2010,and to discuss the correlation between DIC and other environmental factors.The values of DIC ranged from 24.26 to 26.13mg·L^-1 at surface waters,and at the bottom layer waters the values ranged from 24.06 to 26.89 mg·L^-1.The high values of DIC at surface were found at the north area of Dalajia-Sangzhou line,and they were gradually decreased outside.At the bottom layer,the high values were in the south west region,namely,the south of Dalajia.The DIC was found to be negatively correlated with temperature and chlorophyll a,but positively correlated with pH,DO and salinity.Nevertheless,the correlation coefficients were not significant with the environmental factors.

Key words： Daya Bay DIC distribution characteristics
