非层化法计算机模拟三维土壤的优化采样

o characterize soil properties and reduce sampling costs, it is essential to study optimal sampling strategies in three-dimensional soils. In this paper, computer simulations were applied to generate random distributions of soil properties in three-dimensional fields. The generated data were analyzed using the stratified and non-stratified methods. The result indicated that the non-stratified method required fewer sampling columns than the stratified method under the same demanded accuracy. Therefore, the non-stratified method adopted in practices can reduce sampling costs.
