Study On The Three Channels Of The Water Conservancy Cultural Heritage Of The Northern Song And Central Plains

This paper discusses three water conservancy projects named Xianghan Canal,Yin Luo Qing Bian and Yin Huang Ru Yu in the northern song dynasty.They communicate with the Yangtze river,the Huai river,the Yellow River and the northern boundary river.This paper studies the three channels from historical background,geographical environment,influence factors of selection,the causes of failure and the present situation of the site.Furthermore,a more rational and comprehensive proposal for protection of water conservancy cultural heritage is put forward,which can be used for reference for the protection of water conservancy cultural heritage.The Xianghan Canal was planned to communicate with the upper source of the Ying River and the upper source of Bai River,a tributary of the Han River.The aim is to shorten the journey of southwest supplies to capital city.The natural selection of "baihe" water transportation,water conservancy development and "xia lu" and "nanxiang pass",Making the canal line design more rigorous and meticulous.Taking full advantage of the geographical and natural channels along the canal canal to consider the water supply of the canal.However,the low elevation,the flow of water,the quality of the project and the technical level caused it to fail.After the failure,the canal was not protected,and the site of the canal was broken and badly needed.The Yin Luo Qing Bian was a water diversion project of the bianhe diversion port,Reducing the influence of Yellow River water on bianqu,and better contact the Yellow River and huaihe river system.The use of the Yellow River to excavate the channel,save the trouble of digging the valleys,but it is not easy.Underestimating the interaction between the Yellow River,the Bian River and the Luo River,the hydraulic technology and the politics have led to the failure of the project.The remains of the ruins have disappeared under the sharp erosion of the Yellow River,but the archaeological excavation can still witness the glory of the project.It is in the convenient position of the water and land transportation,combined with the "Liangjing Yidao",for better protection and utilization.The Yin Huang Ru Yu project used the Old Sha River to bring the Yellow River into the river,It is convenient for the Yellow River to the north boundary river to consolidate national defence.However,due to the short working time,and the historical record is brief,The previous scholars have discussed the specific situation of the project.Based on the literature and the field study,this paper argues that the Dong Meng Jiangnu River is likely to be the relic of the Yin Huang Ru Yu project.On the basis of this,the protection of the Yin Huang Ru Yu project is integrated into the construction of the Grand Canal and the construction of "eco-cultural tourism belt" in the south-to-north water diversion project.
