摘　　要：为了定量地分析不同温升梯度的温排水对浮游植物的影响,采用FVCOM三维水动力模型计算2011年夏季大小潮、涨落潮时期不同温升梯度温排水的分布特征、影响面积和体积,并根据2011年夏季在象山港海域进行的海上围隔实验数据,分析不同梯度温升范围内浮游植物优势种琼氏圆筛藻的损失量。研究结果表明,夏季表层温排水扩散范围主要分布于1.5℃温升包络线内,底层主要分布于1℃温升包络线内。弱温升区和强温升区内温排水影响海水体积分别为93.650×106 m3及1.073×106 m3,总计94.723×106 m3。温排水影响范围内琼氏圆筛藻的总损失量为3.258×1013 cells,弱温升区占94.76%,强温升只占5.24%。In order to quantitatively analyse the impact of thermal discharge on Coscinodiscus Jonesianus biomass at different temperature rise gradient.A three-dimensional hydrodynamic model was set up to simulate the distribution characteristics,impact area and volume of thermal discharge at different temperature gradient in the summer of 2011 with FVCOM model,and based on the experiment data of enclosure experiments in Xiangshan Bay in summer of 2011,the losses of Coscinodiscus Jonesianus biomass at different temperature gradient ranges were analysed.The results showed that the surface temperature rise range in summer was mainly distributed within the envelope of 1.5 centigrade temperature rise,while the bottom one was within the envelope of 1.0 centigrade temperature rise.The seawater volume affected by weak temperature rise zone and strong temperature rise zone were 93.650 million m3 and 1.073 million m3 respectively,with a total of 94.723 million m3.The total losses of Coscinodiscus Jonesianus biomass influenced by the thermal discharge were 32.580 trillion cells,and the weak temperature rise zone accounted for 94.76 percent,while the strong temperature rise zone was only 5.24 percent.
