Sea reclamation will pollute the environment and reduce the quality of marine water. In order to discuss the impact of reclamation on seawater, 4 heavy metals (Cu, Pb, Zm, Cd) in seawater near Qixingtu were analysized for three time periods: 2007(before the reclamation), 2016(not long after the reclamation) and 2018 (after the reclamation). As a result, concentrations of all the 4 heavy metal met the standard requirements in surrounding seawater of Qixingtu, which indicated a good sea water quality in this area. Except for Cd, all the other heavy metals showed a trend of increasing first and then decreasing. Sea reclamation could indeed aggravate the heavy metal pollution in the surrounding seawater but the impact would recover through reasonable treatment and protection.
