关 键 词：Tuoshan Weir flooding saline water intrusion deposition rate historical hydraulic engineering system
摘 要：This paper is to present an efficient approach to enriching the quantification model of human-rivcrinc interactions and its anthropogenic impact by a retrospective study on one of the four most famous historical hydraulic projects in China,the Tuoshan *** was constructed in 833 AD and had trajectories of natural resilience and hydraulic engineering maturity more than thousand *** historical data and maturation procedure of the hydraulic system were used judiciously to examine the spatial patterns of the long-term water conservancy system with agriculture,urbanization and civilization of Ningbo City m Zhejiang Province,Southeast *** framework is assessed from historical perspective and the deposition rate(DR)is calculated by anatyzing the continuous increase of the Tuoshan Weir *** results show that the declining DR during the 1180 years guaranteed the beneficial role the Tuoshan Weir played in spite of some negative river responses caused by the increase of sediment deposition and decrease of fresh water-retention *** following up revamped workings and well matured hydraulic system around the Tuoshan Weir also contribute a lot to the designed mission of the *** conclude that hydraulic system maturation is very important for the proper function and life span of huge hydraulic projects.
