Heterogeneity is often formed by physics process, chemical action and biological activity under ground surface. Soil macropores, such as cracks and channels that formed by roots and soil animals, are recognized as important pathways for water and pollutant and leads to the heterogeneity. In this research, two geostatistical models are constructed by hypothetical image include uniformly sampling method and stratified random sampling method. The result shows that the stratified random sampling method is better than the uniformly sampling method in that it offers more geostatistical information. Then sequential Gaussian simulation method and simulated annealing method are used to reconstruct the images. The result shows that simulated annealing is superior in better reconstructing the image because of its ability of using more statistical information.
