摘要
海河水系以"清"为名的大清河其实只是相对于位居其南、其北著名浊流滹沱河与永定河而言的"清"河。历史时期,随着上游水土流失的日益加剧,大清河南系各河含沙量不断增高,干流段决徙逐渐频繁。本文利用历史文献,对先秦以来在自然与人类活动共同影响下的大清河南系的变迁进行了探讨,揭示和总结了两千余年来水系格局变动的基本过程及主要特点。大清河南系又是白洋淀湖群地表径流补给最大的水源,上述研究结论还将是理解和分析这一著名湖群演变不可忽视的重要基础。
The Daqinghe River was in general not as muddy as the Hutuohe River to its south or the Yongdinghe River to its north. However, with the intensification of soil losses at the upper reaches, the southern branches of the Daqinghe River saw higher and higher sediment concentration and its mainstream frequent migration. An in-depth analysis has been carried out about the water system evolution as a result of natural factors and human activities, which leads to a clear description of water system evolution of the southern branches of the Daqinghe River and a list of the major characteristics of its migration of river channels. The southern branches of Daqinghe River are the most important water source of the Baiyangdian Lake, which is of great significance to the Haihe River basin. Thus, These findings are considered to be vital to the study on the evolution of the Baiyangdian Lake.
