Based on development of grey separate-sequence and higher-step dynamic Model,multi-variable and higher-dimension exponential non-linear model was established,and the methods of searching-identifying non-linear parameters was developed aiming at limited applicability and low simulated precision of general statistical models of soil erosion.The model s strongpoint is great information contain,strong opening of model s structure,wide applicability and so on.Searchingidentifying parameters is simple and operate...
