中文摘要：

文章推荐了一种半封闭海湾纳潮量的直接观测方法，主要利用ADCP在封闭湾口的观测断面上进行周期性的往还式周日连续走航观测，通过观测到的湾口流量变化序列直接计算海湾的纳潮量。文中提供了较为系统的观测方案以供借鉴。

英文摘要：

A direct observation method of storage capacity for tidal water of semiclosed bays is proposed in this paper. If the continuous, come and go underway observation has been done recurrently by ADCP at the section which close the doorway of the bay among at least 2 6 hours, a series of flux of the bay could be obtained and the storage capacity for tidal water of the semiclosed bay could be computed directly. In addition, a systemic observation project about the method is proposed in this paper.
