【Abstract】 Based on statistical data on municipal domestic refuse yields from 1990 to 1999 in Shanghai city,the method of grey correlation coefficient analysis was used to quantitatively study the key factors affecting refuse yields.A grey dynamic model GM(1,1) was established to predict the generation amount,the prediction precision of GM(1,1) model was tested by residual-revision method and was proved to be feasible and suitable.The method and results of this study was useful for management and planning of municipal domestic refuse yields in Shanghai city.更多还原
