The results showed that at the highest tide level, the concentration of Coliform group in the harbor area was significantly decreased, and the distribution of the concentration of Coliform group was significantly lower than that of the control group. The concentration fell below 5% at the south of the Pier 44 and near the ferry at No. 45, with about 10% of the Coliform group distribution along the north side of Pier No. 44; at the lowest tide level, the Coliform group concentration was distributed from Central South Bridge to the direction of the harbor. The range of the influence went furthest to the south sea area of the 44th South Pier. The concentration of Coliform group changed from 70% to less than 5%. According to the results of the study, the range of the pollutants is concentrated in the vicinity of Anliang Port estuary. Under the action of tide, the pollutants near the estuary are diluted by the tide and have no effect on the water quality of the water in the harbor area.On the whole,Taichung Port water body conforms to Class B sea area environmental standard; In addition to, from the analysis of the main components, salinity has a negative correlation with the Coliform group population, and the increase of salinity due to the high tide may also be the reason for the decrease of the concentration of Coliform group.
