Seasonal Variation of Nutrients and Environmental Impact Factors in Sanggou Bay
The seasonal variation and horizontal distribution of nutrients including inorganic nitrogen (DIN), phosphate (PO43--P), and silicate (SiO32--Si) as well as environmental impact factors in Sanggou Bay were analyzed based on four investigations during 2006 to 2007. The results show that the main form of DIN was nitrate (NO3--N) with proportion above 50%. The seasonal variation and horizontal distribution of nutrients were significant. P and Si were the limiting factor for the growth of phytoplankton in summer and winter, respectively. Besides, P was a potential limiting factor in spring and autumn. There was a canonical correlation between nutrients and water quality factors with the maximum coefficient of 0.898 between NO3--N, nitrite (NO2--N), PO43--P, and temperature (T), total alkalinity (TA), salinity (S), pH.
