| Abstract: | An artificial neutral network model was developed to evaluate the nutrient states of sediment sample in Lake Donghu,Wuhan.With six factors such as TN,TP,TOC,SRP,TSL and pH chosen as the input,the training sample and testing sample were established,and results of organic assessment were chosen as output to evaluate the nutrient.Through analysis of model,results of fertility assessment showed that the organic index in the whole Lake is higher than standard level of fertility in sediment.Six samples which were... |
