Construction of Price System Dynamics Model of Water Resources Under the Promotion of Unconventional Water Sources——Through Taking Ningxia Area as an Example
Construction of Price System Dynamics Model of Water Resources Under the Promotion of Unconventional Water Sources——Through Taking Ningxia Area as an Example
The study analyzes the water resource pricing under the promotion of unconventional water sources utilization;reduces the contradiction between supply and demand of water resources;builds a system dynamics model of water resource price within the region with system dynamics method and vensim software;determines the time range and space range based on the economy,society,environment and ecology of Ningxia;and analyzes various factors affecting water supply price.According to the causal relationship between the factors,the study determines the variable equation,and conducts historical test and sensitivity analysis of the model with the historical data.The results show that the model can be used for subsequent simulation analysis through historical test and sensitivity analysis.
