| 摘 要： | 介绍了几种关于水交换的概念和模型。认为以水质模型模拟半交换时间研究海域的水交换能力更全面、客观。对渤海水交换的研究表明 ,由于渤海环流结构及季节变化 ,使得渤海 3个海湾及渤海中部交换能力相差很大 ,莱州湾交换能力最强 ,辽东湾特别是其西部海域交换能力最弱。交换时间与物质初始浓度无关 ,与投放时刻、外源强迫密切相关。在治理渤海环境时 ,应分区进行 ,注意选择污染物排放时间和位置

| Abstract: | In this paper some concepts and models for water exchange in the coastal sea are introduced. Half life time, simulated by a dispersion model, can represent the exchange ability of an area more completely and objectively. Study on the water exchange of the Bohai Sea by using this approach shows that the Laizhou Bay has the highest exchange ability and the Liaodong Bay, especially in the northwest part, has the lowest one. Half life time is independent of the initial concentration, but dependent on the initial time and the extra load. The best time and place for discharging the waste water should be chosen for different areas. |
