Prediction and Assessment of Potassium Salt Resources Carrying State in Qarhan Salt Lake Based on System Dynamics
With the increasing demand for potassium chloride,the intensity of potash resource exploitation in Qarhan Salt Lake is constantly improving,and resource depletion is imminent.Aiming at this situation,the carrying rate index of potash resources was designed to describe the degree of overmining,and a dynamic model of potash resource mining system in Qarhan Salt Lake was constructed.Five scenarios were set to de-scribe the future developments,and the carrying status of potash resources in Qarhan Salt Lake in the next 20 years was predetermined.The results of salt lake water resources and potash resource carrying rate in forecast period show that due to the trend of climate warming,the carrying rate of water resources of Qarhan Salt Lake will decrease in the future,but the overall situation is still in an overloaded state.The sustainable supply of pot-ash resources can be ensured by reducing mining intensity and improving the technical level.So it is necessary to rationally formulate production plans and improve technical research.
