- Abstract
This paper established the system dynamics simulation model and the evaluation model (CN-AM) of the IRSN inNandu River. The development trend of IRSN and its subsystems in the Nandu River in 2012, 2014, 2016, 2018 and 2020 were obtained. The water system connecting link value and evaluation grades of the water systems in different periods were got through five programs. The results show that a) in 2012, 2014, 2016, 2018 and 2020, the connectivity of subsystems in the Nandu River system are 2.698-2.745, the natural function and social function subsystems are 3.682-3.731 and 3.616-3.662. The overall condition of the Nandu River system is 3.485-3.529, being in a state between the middle and good. The main limiting indicators are river frequency, water connectivity, annual average runoff guarantee rate, water body pollutant capacity, river water quality compliance rate, percentage of surface agricultural water supply, reservoir regulation ability index and percentage of surface urban water supply and; b) IRSN in Nandu River rates between the middle and good. In 2020, the evaluation grades of the water systems for other 4 programs are higher than that of the regular development mode. The ecological priority mode (0.332), the resource development mode (0.312), the flood control mode (0.352) and the comprehensive development mode (0.397) are all bigger than that of the conventional development mode (0.200).
