The Best Model of Spatial Optimal Estimation for Spatial Variability of Porous Media's Heterogeneity in Water Environmental Simulation

Xu Yongli,Zhang Zheng,Gu Shiyan,Zhao Juan (College of Natural Resources & Environment,Beijing Forestry University,Beijing 100083,China)  
We were often asked to give credible estimation of permeability parameters on the spatial distribution data of water-bearing media in daily practice.How to get satisfactic estimation on appointed permeability parameters through known data was a problem,which had called the attention of hydrogeologists and workers of applied mathematics.In this paper,the geostatistics theories and methods of depicting regionalized variables-which have both stochastic and structural characters were used to analyse the parameters that can reflect the porous media.From the result,we could get the best model of spatial optimal estimation for parameter's Spatial Variability ——ordinary Kringing.
