Abstract: In view of the uncertainty of each parameter in the model of Dillion, the parameters were managed by using the theory of blind number and blind number mean. The permissible input of total phosphorus of Lu Lake in Guangzhou and the credible level were calculated. Compared with the classical method, the blind number method is more reasonable and credible according to the results of the sample.

Key words: uncertainty, blind number mean, total phosphorus, Dillion model
