IOWGA operator and Markov chain to groundwater depth prediction

摘要：

　　The groundwater depth change is a complex nonlinear process.Falling groundwater level will rise to a series of environmental problems.A groundwater depth combination model which based on vector cosine angle IOWGA Operator and Markov chain is proposed to solve the problems about not extensive source of information for the single model and the shortage of tixed weights for the combined model.Take the long-term observation well (16 years) groundwater depth date in Daan for example,the combination prediction method which based on index model,grey model and linear regression model is used to simulate and predict groundwater depth.The example shows that the model has a better prediction accuracy.
