史前郑州地区黄河河流地貌与新构造活动关系初探

Preliminary Study on the Relationship between the Fluvial Geomorphology and the Neotectonic Movement in Yellow River in Zhengzhou Prehistoric Times

虽然历史时期黄河在郑州地区与桃花峪冲积扇上的变迁已有较为系统的研究,但是由于上古文字资料的欠缺,相关研究的不足,关于史前时期黄河在大郑州地区的河流地貌特征、河道在黄河下游冲积扇上部演变的论述甚少,认识还非常粗浅.文中试就黄河下游演变意义上至关重要的郑州大区和史前黄河在桃花峪以上特定地域的河流地貌、河道演变与新构造活动的某些关联问题以及郑州西部构造地貌对于河湖水系演化的作用提出一些看法.

Though there has been systematic research on changes of Yellow River in Zhengzhou area and Taohuayu alluvial fan in the historical period, discussions about the fluvial geomorphological features of Yellow River and the channel evolution in the upper alluvial fan in the lower Yellow River in prehi storic period are little and the related understanding is superficial for lack of ancient text data and relevant researches.In the paper,some opinions are put forward for Zhengzhou district significant to the evaluation of the lower Yellow River and the special fluvial geomorphology of prehistoric Yellow River as well as some problems about channel evaluation associated with the neotectonic moveme nt and the effect of tectonic geomorphology in western Zhengzhou on the evaluati on of rivers and lakes.
