| 电厂温排水对海域环境影响倍受关注，依托现场原型监测资料验证基础对其温升影响范围合理科学评估是目前面临的新问题。本文采用数值模拟、现场水面观测、遥感监测对某滨海电厂海域温度场的影响开展了对比研究，研究结果表明：计算的温升影响区和遥感监测的温升影响区位置和形态符合，并且计算的温升影响面积与遥感监测值平均偏差在±20%以内；现场固定点水温观测结果，模型计算值与水面实测值的随潮过程吻合较好，计算值与水面实测值温升平均误差在±0.5℃以内。依据验证研究，探讨了在海域温度场验证中应把握的温升分布形态和位置、温升梯度和温升面积等验证原则和顺序，以及背景温度场的取值依据和遥感资料分辨率等问题。本研究可供温排水环境影响评价参考借鉴。 |

| The impact of thermal discharge from power plants on the marine environment has attracted much attention. Based on on-site prototype monitoring data verification, a reasonable and scientific assessment of the temperature rise impact range is currently facing a new problem. This article conducts a comparative study on the impact of numerical simulation, on-site water surface observation, and remote sensing monitoring on the temperature field in the sea area of a coastal power plant. The results of the study show that the location and morphology of the calculated and remotely monitored temperature rise impact zones are consistent with, and the calculated temperature rise influence area has an average deviation of ±20% from the remote sensing monitoring value; The on-site fixed point water temperature observation results show good agreement between the calculated values of the model and the measured values on the water surface during the tidal process, with an average temperature rise error of ±0.5℃ between the calculated values and the measured values on the water surface. Based on verification research, this paper explores the verification principles and sequence of temperature rise distribution patterns and locations, temperature rise gradients, and temperature rise areas that should be grasped in the verification of sea temperature fields, as well as the basis for background temperature field values and remote sensing data resolution. This study can serve as a reference for environmental impact assessment of thermal drainage. |
