摘要
mary name="EnDivSummary">Land subsidence shows a nature of hysteresis effect comparing with the fluctuation of groundwater table. An Almon Lag model is built taking hysteresis into account, which is used to forecast the subsidence based on the data of a specific time step collected in Cangzhou. In addition, the result is compared with the outcome exported from GM (1,1) model and NN model. It shows that the Almon Lag model has a superior result and higher precision with regard to the other two models.
