Flood Control in the Lower Yongding River During the Late Qing Dynasty and Its Impact on Hydrological and Soil Environment
The measures taken by the late Qing government to control the flooding of the Yongding River fol-lowed those implemented by the previous dynasties and during the early and middle Qing Dynasty,includ-ing the construction of dams,dredging of rivers,and repair of gates and dams,which achieved certain re-sults.However,they caused many negative impacts on the hydrological and soil environment,including the aggravation of sedimentation and diversion in the lower reaches of the Yongding River,the deterioration of the original hydrological environment of surrounding lakes and lakes,and the problem of soil desertifi-cation and salinization in the lower reaches of the Yongding River,which to some extent exacerbated the difficulty of river flood control.During the reign of Emperor Jiaqing and Emperor Daoguang,due to the deterioration of the financial situation of the Qing government,the emergence of corruption in river de-fense,and the limitations of the appointment of river defense officials,the governance of Yongding River fell into difficulties.Summarizing the experience and lessons of flood control in the lower Yongding River since the late Qing Dynasty can help better understand the changes in the interaction between the river environment and the human governance environment in the region,and provide historical references for the special situation faced by contemporary Yongding River governance.
