| 英文摘要 | A one-year field study was conducted to determine the conversion ratio of phytoplankton biomass carbon (Phyto-C) to chlorophyll-a (Chl-a) in Jiaozhou Bay,China.We measured suspended particulate organic carbon (POC) and phytoplankton Chl-a samples collected in surface water monthly from March 2005 to February 2006.The temporal and spatial variations of Chl-a and POC concentrations were observed in the bay.Based on the field measurements,a linear regression model II was used to generate the conversion ratio of Phyto-C to Chl-a.In most cases,a good linear correlation was found between the observed POC and Chl-a concentrations,and the calculated conversion ratios ranged from 26 to 250 with a mean value of 56 μgμg-1.The conversion ratio in the fall was higher than that in the winter and spring months,and had the lowest values in the summer.The ratios also exhibited spatial variations,generally with low values in the near shore regions and relatively high values in offshore waters.Our study suggests that temperature was likely to be the main factor influencing the observed seasonal variations of conversion ratios while nutrient supply and light penetration played important roles in controlling the spatial variations. |
