| 摘 要： | 冲刷时间是表征河口水体交换的一个非常重要的物理量．本文在回顾潮汐河口冲刷时间研究现状的基础上，分析了影响冲刷时间的主要影响因子．结论表明冲刷时间不仅是潮棱体和淡水径流量的函数，而且与河口形态、天气要素密切相关，各要素之间的非线性关系更增加了冲刷时间研究的复杂性．在今后的研究中，应以河口界面的观点，加强河口冲刷时间界面机制的研究，并注重人类活动对冲刷时间的影响．

| Abstract: | Flushing time is a very important concept that expresses theexchangeof waters in estuaries; based on the review of the advancement of flushing time, this article analyses the main factors that affect the flushing time. Conclusion is obtained that flushing time is not only a function of tidal prism and discharge of fresh water, but also has close relationships with estuarine (geometry) and weather factors. Non-linear relationships among these factors enhance the complexity on studying the flushing time. We should strengthen the study of the physical mechanism on flushing time with a view of interface, and pay attention tothe impact of human activity on (flushing) time in future research. |
