Prediction Model of Soil Nutrients Loss Based on Artificial Neural Network

摘要

On the basis of Artificial Neural Network theory, a back propagation neural network with one middle layer is building in this paper, and its algorithms is also given. Using this BP network model, study the case of Malian-River basin. The results by calculating show that the solution based on BP algorithms are consistent with those based multiple-variables linear regression model. They also indicate that BP model in this paper is reasonable and BP algorithms are feasible.
