【摘要】：本文通过历史文献与考古资料综合考证出汉唐渭河三桥的位置,并以其与今天的渭河河道相对比,探讨了历史时期西安咸阳间渭水河道北移的时空特征。结论认为除汉西渭桥处的渭河基本没有侧蚀变动外,中渭桥、东渭桥两地的渭河都向北移动了较大距离,中渭桥处汉末至今1808年间渭河向北移动了3630米,平均每年北移2米左右;东渭桥处唐末至今1118年间渭河北移了2600余米,平均每年北移2.3米有余。影响渭河发生侧蚀北移的原因主要为新构造地质运动、水文特点与两岸土质等自然环境要素,而人为活动也起到了不应忽视的作用。
[Abstract]:Based on the historical documents and archaeological data, this paper comprehensively studies the location of the third bridge of Weihe River in Han and Tang dynasties, and discusses the temporal and spatial characteristics of the northward movement of Weihe River between Xianyang in Xi'an during the historical period by comparing it with the Weihe River today. The conclusion is that the Weihe River in Zhongwei Bridge and Dongwei Bridge have moved northward except for the Weihe River in the west of Han Dynasty. The Weihe River moved 3630 meters to the north between the end of the Han Dynasty and the end of 1808 in the Zhongwei Bridge, and the Weihe River moved northward from the end of the Han Dynasty to the end of 1808. From the end of Tang Dynasty to 1118 years, the Weihe River moved more than 2600 meters to the north, with an average annual northward movement of more than 2.3 meters. The main factors affecting the northward movement of the Weihe River are the neotectonic geological movement, hydrological characteristics and the soil quality of the banks, and human activities also play a role that should not be ignored.
