| Abstract |
In Jinhae bay, the physicochemical, biological and ecological surveys were carried out 65 times at six sites both in surface and bottom water from July 1976 to December 1982. Twenty one abiotic and biotic parameters were determined on each sample. These data were subjected to factor analysis to scrutinize the effects of environmental conditions on water quality and ecosystem. The phytoplankton blooming was the major factor of the variance of the water quality and ecosystem in Jinhae bay. Fresh water inflow was second factor at site 1 and 6, and it was third factor in site 3 and 5. The nitrogen inflow was also play an important role, which was second factor at site 2, 3, 4 and 5, and third factor at site 1. Beside above factors, the increasing of organic materials, waste water inflow, precipitation and recycling of nutrients, upwelling of sediment, nutrient salts and photosynthesis were also determined for the variation of water quality and ecosystem. |
