大凌河及小凌河历史变迁分析

Analysis on Historical Changes of Dalinghe River and Xiaolinghe River

大凌河及小凌河是东北地区非常重要的两条河流。通过追溯两条河流的历史,采用研究历史文献和对比各时期地形图相结合的方法,系统分析研究两流域历史变迁过程及原因,有助于分析今后发生河道变迁的可能性,为因势利导地安排工程措施提供参考。

Dalinghe river and Xiaolinghe river are two important rivers in Northeast China. By tracing the history of the two rivers, using the method of combining researching on the historical documents and comparing the topographic map in every period, this paper made systematic analysis and research of historical changes process and causes in two drainage basins. It was conductive to analyze the possibility of channel change in the future, and provided reference for improving the occasion to arrange engineering measures.
