摘　　要：通过1992年冬、夏季盐度资料分析,认为黄茅海的盐度最大值和最小值均发生在涨憩和落憩时刻,通常比潮位的峰、谷值滞后1～2h.盐、淡水主要呈缓混合和强混合型.盐水楔活动范围较大,夏季随涨、落潮进退于赤鼻岛与栏门浅滩之间;冬季逼近口门,咸水可入侵到河口内陆20～50km.Analysis of the salinity data of the summer and winter 1992 shows that the maximum and minimum salinity value in Huangmaohai Bay came, respectively, about 1 to 2 hours after the peak value of high tidal level and valley value of low tidal level. The saline water and fresh water mixed slower in summer but stronger in winter. The active range of the saline wedge was large, advancing and retreating between the Chibi Island and the sand bar at flood and ebb tide in summer, while going up by 20-50km into the river mouth on the bay in winter.
