The hydrogeochemical evolution of Bosten Lake has an important impact on the lake’s ecology and water environment. Kriging interpolation, principal component analysis Piper Gibbs charts were used to analyze hydrochemical characteristics genesis in summer autumn. following are main conclusions: (1) In autumn, hydrochemistry lake follows order SO42− > Cl− HCO3− Na+ Mg2+ Ca2+ K+. (2) concentrat...

Prediction by kriging does not rely on any specific model structure, and is thus much more flexible than approaches based on parametric behavioural models. Since accurate predictions are obtained for extremely short training sequences, it generally performs better than prediction methods using parametric models. Application to nonlinear system inversion is considered
