Abstract: 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.
