摘要
对全新世以来山东半岛东北部沿岸的相对海面（基准面）变化，不同河流有截然不同的地貌响应方式。大沽夹河型河流的下游河谷中有分别与相对海面升降对应的溯源堆积期和溯源侵蚀期，但不同规模的河流仍有差异。黄水河型河流河谷未因基准面升降而发生侵蚀或堆积，河谷仅起了输沙通道的作用。此外，大沽夹河型河流的中下游河型在相对海面上升或下降时，还可能发生相应地网状化或曲流化。
To the same Holocene relative sea level (base level) changes along the Northeastern Shandong peninsula, different rivers have adopted two different geomorphic response ways. In the middle and lower Dagujia type river valleys, there are backfilling and headward erosion stages which accompanied relative sea level rising and falling stages respectively, and there are still differences among rivers with different scales. In the Huangshui type river valleys, no aggrading and incising stages, which resulted from the Holocene base level changes, have been found, and the valleys have only played a role of transporting the debris from the upper drainage basins into the sea. For the middle and lower Dagujia type rivers, the meandering and braided river systems have developed in response to the relative sea level falling and rising respectively.
