This paper determines the calcium carbonate content in 213 surface sediment samples from the South China Sea (SCS) in order to have a comprehensive analysis of the distribution character of calcium carbonate and its controlling factors in surface sediments of the SCS. The results show that there are different influence parameters in distributions of calcium carbonate in various regions. In the shelf, calcium carbonate contents are low owing to largely terrigenous material input. In the slope, calcium carbonate contents are high due to abundant supply of calcareous organisms, low terrigenous material input and weak dissolvability. In the deep basin, calcium carbonate contents are very low because of strong dissolvability.
