Based on the characteristics of Kriging variance, this paper analyzed the accuracy of Kriging estimation on parameters random fields in water environmental simulation. Results showed the accuracy of estimation was determined by the many factors such as variogram, distribution of sampling sites and so on, and researched preliminarily the identification and treatment of the outliers which exert a great influence on the accuracy of Kriging estimation in the light of a practical example.
