长江口邻近海域春季藻华期间浮游植物生物量与环境要素的拟合分析
Fitting analysis of phytoplankton biomass and environmental factors in the coastal waters adjacent to the Changjiang River estuary
摘要
Abstract
On the basis of the 2005 survey data from the coastal waters adjacent to the Changjiang River estuary, nonlinear fitting methods were used to establish equations representing the quantitative relationships between phytoplankton biomass and inorganic nutrients, temperature and salinity during the diatom and dinoflagellate blooms. The optimum values of dissolved nitrogen, phosphate, silicate, temperature, and salinity for the diatom bloom were calculated to be 10.1μmol/L, 0.21μmol/L, 6.39μmol/L, 11.9℃, and 30.5, respectively, and those for the dinoflagellate bloom were 3.98μmol/L, 0.18μmol/L, 22.0℃, and 27.2, respectively. These optimum conditions could be treated as key environmental parameters that provide references for further studies on numerical simulation and parameter optimization of harmful algal blooms.关键词
