摘　　要：基于三维非结构网格有限体积海岸与海洋模型(FVCOM),模拟了湄洲湾受某电厂温排水影响海区的温度场分布与变化特征,并结合5个站位连续24h同步海流、温度观测资料,对该海区温度场进行分析研究。结果表明,该海区不同区域在不同潮时下,温度垂向分布具有明显不均匀特征,出现这一特征主要同各区域与电厂排水口相对位置、潮流场及地形因素有关。Based on a 3-dimensional unstructured grid finite volume coastal ocean model （FVCOM）, the distributions and variations of the temperature field in the Meizhou Bay waters influenced by warm water discharge from a power plant are numerically simulated, and the characteristics of the temperature field are studied based on the current and temperature data observed 24 hours synchronously at 5 stations in the region studied. The results indicate that the vertical distributions of water temperature are distinctly non-uniform in different areas and at different time of tide. Such characteristics are mainly related to the distance between the individual areas and the outlet of the warm water discharge, and to the tidal field and the seafloor topography as well.
