| 摘 要： | 根据实测资料，对黄河口拦门沙区近期的演变情况进行了分析，近几年来，在人工干预及枯水枯沙等因素的综合作用下，拦门沙的顺河长度有所缩短，坎顶高程有所降低，但拦门沙淤积体仍是不断向海域推进的，在分析的基础上，提出了黄河口拦门沙的演变模式，并运用此模式对拦门沙的淤进与蚀退等现象进行了定性的描述。

| Abstract: | sing field measurements. the variation of the sediment bar at the Yellow River Mouth wasanalyzed. In recent year, the longitudinal length of the sediment bar has decreased due to humaninterference and low water runoff and less sediment load. The crest elevation of the bar has alsoreduced. However, the bar still moves forward to the sea. From this study, an evolution model for thesediment bar was proposed' Using this model, the phenomenon of deposition and erosion of the barwas described qualitatively. |
