Abstract:The spatial distributed parameters in groundwater environmental assessment bear complex uncertainty. In this paper, the characteristics of spatial structure and random in the spatial distributed parameters are analyzed. The principles and approaches of spatial statistical analysis on distributed variables are also elaborated. As a result of applying a new statistical method to analyze the uncertainty in the spatial distributed parameters, the deficiency of classical statistics in analysis on randomness of spatial distributed parameters of groundwater environmental assessment can be remedied, thus the spatial structural information and the spatial optimum estimation of the distributed parameters can be gained. As such, the spatial statistical analysis on spatial distributed parameters in groundwater environmental assessment tends to be more practical and rational.
Keywords:stochastic variables  environmental assessment  spatial distributed parameters  groundwater
