Assessment and Analysis of Fotan Bay Water Quality in Fujian Province

Single-factor pollution index assessment,eutrophication index assessment and organic pollutants index were adopted to evaluate and analyze the water quality of Fotan Bay,which are based on the investigation in spring and autumn. The result shows the concentrations of all monitored items in Fotan Bay seawater are less than the limited concentrations put forward by government,except to inorganic nitrogen and active phosphate,which become to be the main limiting factors influence the seawater environment of Fotan Bay; the water environment of Fotan Bay is in a serious state of eutrophication and a moderate state of organic pollution. The water environmental quality of Fotan Bay on autumn is better than that on spring. This research was made to provide scientific basis for the development and utilization of sea resources in Fotan Bay.
