唐代淮河北岸主要支流流量变迁及其现代保护

The change of main tributary flow in the north coast of Huaihe during the Tang Dynasty from the angle of shipping

唐代淮河北岸的主要支流有颍水、泗水、沭水、沂水、汝水等,通过归纳总结文献资料以及对它们的航运情况进行分析,可以看出这些主要支流的流量从先秦至唐一直都保持一个比较稳定的水平。影响唐代淮河北岸主要支流流量的最重要因素是森林,颍水、泗水、沭水、沂水、汝水流域,尤其是上游地区良好的森林覆盖状况保证了这些河流流量的相对稳定,也从侧面说明唐代淮河北岸水文环境优良。而面对现代淮河北岸支流新出现的水污染严重、水环境恶化等问题,需要严格控制污染源、综合利用各种物理、化学和生物——生态修复措施才能逐步改善。

In the Tang Dynasty, the main tributary of the north shore of Huaihe was covered with Yingshui, Sishui, Shushui, Yishui, Rushui, and so on. Through the summary of literature and the analysis of their shipping conditions, we have found that the main tributaries flow had been maintained at a stable level from Pre Qin to Tang Dynasty. The most important factors affecting the flow of the main tributaries of the north shore of Huaihe in the Tang Dynasty are the forest, the basin of Yingshui, Sishui, Shushui, Yishui,Rushui, especially the good forest coverage in the upper reaches which ensures the relative stability of stream flow, indirectly indicting that the hydrological environment on the north shore of Huaihe was excellent in Tang Dynasty as well. In the face of water pollution and serious deterioration of water environment and other issues in the north coast of Huaihe, we should take measures to control pollution source strictly and utilize comprehensive of all kinds of physical, chemical and biological-ecological methods, and the situation may improve gradually.
