摘要
Abstract
Gray theory is effective reconstruction of the regularity of the time series processing and forecasting time series process.From the perspective of long-term projections,GM(1,1) model for time series prediction can achieve the desired effect.In this paper,the nearly 20-year peak flow observed in Enshi city,Qingjiang River peak flow changes there is a certain cyclical calculation results show that the GM(1,1) model:first order differential equations exponential function of the law,not very better reflect the periodic fluctuations in peak flow variation,at the same time there are great limitations that flow projections of single factor.关键词
