Abstract: The temporal and spatial distribution of seawater transparency was analyzed according to the marine monitoring data of Qingdao coastal area in 2014. Multiple linear regression analysis was utilized to find out seven key environmental factors as the independent variables, and an optimal multiple linear regression statistical model was established. In addition, the single-factor correlation analysis and curve fitting analysis were also utilized to further prove that the seawater transparency was significantly correlated with the content of chlorophyll a, suspended matter and water depth, and the curve fitting equation is drawn.

Key words: Qingdao coastal water, seawater transparency, environmental factors, statistical analysis
