| 摘 要： | 对 1 994年 8月在鸭绿江河口的水文和悬浮泥沙的观测资料进行分析。结果表明 ,在洪季鸭绿江河口的最大混浊带 ,出现在第一个河口锋面内侧。它的核心处盐度小于 1 ,从上游带入河口的细颗粒泥沙多数被河口第一锋面截留 ,还有一部分上游来沙穿过该锋面 ,聚集在河口第一和第二锋面之间。垂向密度环流作用和絮凝作用在鸭绿江洪季最大混浊带的维持过程中起着主导作用

| Abstract: | Based on the observation data from two transects and two time\|series stations in Yalujiang River estuary in August 1994, the hydrological features and features of suspended silt of the turbidity maxium belt in wet season are described. The selinity at the center of the belt was below 1, which occurred at the inner side of the first estuarian front. Most of the suspended load from the upper reaches was trapped by the front and the rest deposited bewteen the first and second front. Vertical density circulation and flocculation played important roles in keeping the turbidity maximum belt of Yalujiang River estuary during wet season |
