摘　　要：为解普兰店电厂温排水对海水环境的影响,采用水动力及对流-扩散方程的二维潮流及温度扩散数学模型进行了潮流及温度场数值模拟,分析了温排水排放对周边海水的影响,统计了不同温升的包络面积。结果表明:由温排放导致的温度扩散主要集中在排水口附近区域,冬季温升超过0.5℃的面积约为0.0572km^2,温升大于1℃的范围仅0.0001km^2;夏季温升大于1℃的范围均位于水道内,面积为0.0551km^2,不会影响到水道外侧的普兰店湾海域;温升大于0.5℃的海水面积约为0.0118km^2,影响范围为水道内及水道外侧约0.0045km^2的局部海域。To research the impact sonsea water environment by warm water emission for power plant in Pulandian, hydrodynamics and advection--diffusion equation, a 2--D numerical model for tidal current and warm water were used. We used this model to understand warm water drainage＇s impact on the surrounding seawater, then made sta- tistics on the envelopes of different temperature rise. The results showedthat thetemperature diffusion caused by the warm water emissions were mainly concentrated in the vicinity of drain. The diffusion area with temperature rise a- bove 0.5℃ was about 0.0572km2 when the temperature rise above 1℃ was about 0.0001km2 in winter. The diffusion area with temperature rise above 0.5℃ was about 0.0118km2 when the temperature rise above 1℃ was about 0. 0551km2 in summer.
