| 摘 要： | 本文报道了５套泥沙捕集器在１９８７年８月１３－１７日和１９９０年２月２２－２６日期间在长江口北槽航区域现场投放和观测，集沙杯由有机玻璃制成，内径为５ｃｍ，杯高２１ｃｍ。对在小风情形，小风转大风情形和寒潮大风情形下集沙杯捕获沙样的干重和沙样的中值粒径垂直分布的特征分别作了描述，阱而为大风浪引起航槽游积及其底沙粗化提供了确凿证据。

| Abstract: | Field deployment of five sediment trap arrays in the area of the North Passage in the Changjiang Estuary in Aug. 1987 and in Feb. 1990 are reported in this paper. Sediment traps are constructed of cylinders, 5 cm in diameter and 21 cm tall, of plexiglass. The characteristics of vertical distribution of mass of captured material in sediment traps and its median sediment size under the conditions of light breeze, of light breeze to strong breeze and of cold wave are respectively described. Thus, furnished here are the convincing proves of accretion of the North channel and bed-load sediment coarsening due to wind and wave actions. |
