| 摘 要： | 华北山地的水系在第四纪有过重大变迁。其变过时段主要发生在早更新世早期和晚更新世早期，其次是早全新世和晚全新世。变迁方式主要是河流自下游面上游的溯源侵蚀袭夺，且袭夺点逐渐向下游移动；其次是断陷盆地的阻隔与诱导。变迁方向多是东西向河道袭夺南北向河道，使河流向东改道。目前许多河流仍处在进一步袭夺中，从而可看出，华北山地的水纱变迁严格受新构造运动控制，且以断块差异活动为主，水系变迁方向可能与青藏高原在第四纪强烈隆起和太行山，燕山在第四纪迅速抬升有关。

| Abstract: | significant changes had taken place in the river system in north China mountain area.They happened mainly in the early stage of Early Pleistocene and the early stage of Late Pleistocene,secondly in Early Holocene and Late Holocene.The main form of change was river erosion and capture from the up reach to the lower reach,and the capture site moved toward the lower reach;second is the obstruction and inducement of downfaulted basin.The changes mostly were the rivers in west-east direction captured the river in north-south direction,and made river change its riverway toward east.At present,many rivers are still on capturing.Hence,the river system's change in north China was controlled strictly by the new tectonic movement,and mainly by the movement of blocks' difference.The direction of river system's change may be relevant to the uplift of Qinghai-Tibet plateau and the quick rising of Taihang Mountain and Yanshan Mountain in the Quaternary period. |
