基于河流连续性的渭河西安段历史变迁研究

Research on Historical Changes in Xi’an Section of Weihe River Based on River Continuum

本文以河流连续性的视角,借助历史地理学的方法,对渭河水文变迁及其原因进行研究梳理,旨在从景观生态学的角度给出一定的规划指导。通过研究渭河向北偏移和水量变化两个方面的变迁历史,以及影响其变化的自然因素和人为因素,得出人类在大肆改造和利用自然的过程中,对渭河自然过程的连续性造成了破坏,加剧了渭河的变迁的结论。

From a view of river continuum,the purpose of this paper is to study the hydrological changes of Weihe river and corresponding reasons by the method of historical geography,and to give certain planning guidance from the perspective of landscape ecology.Through research on the change history of northward move and runoff of Weihe river and also the natural factors and human factors resulting in the changes,it can be concluded that human beings have destroyed the continuity of the natural process of Weihe river and aggravated the vicissitudes of Weihe river during transformation and utilization of the nature.
