The systematically distributed agricultural non-point source pollution model based on physical basis has been built in recent years.However,the deficiency of time and space monitoring information input and the uncertainty of parameter estimation are still a significant problem limiting the model application at different basin scale.So according to the influence factors of non-point source pollution production and its uncertainty,in this paper the production and its influence factor's time and space variability of non-point source pollution are analyzed.At the same time how to quantitatively direct exploration and monitoring variables by utilizing stochastic theory and multivariable statistics principle and variability analysis method so to set up a rapid and effective stochastic monitoring mechanism is explored.The research analysis will benefit the regional agricultural non-point source pollution monitoring,control and management in future and also can provide reference for non-point source pollution modelling and prediction research on basin scale.
