水及溶质在有大孔隙的土壤中运移机制研究进展

综述了水及溶质在有大孔隙的土壤中运移的实验和模型研究进展，指出：今后应通过大量的室内外实验和改进观测方法来获得大量的数据资料，从定性和定量两方面来研究大孔隙流；只有在参数的测定和一些量的确定技术解决以后，模型才能得到完善而达到实用的程度；为解决大孔隙系统流动过程中的高度非线性和非稳定性问题，需要新的模拟方法和数值计算方法；今后模拟研究的重点应是随机模型而不是确定性模型。

Advances in Study of Water and Solute Transport Mechanism in Macroporous Soil

Advances in the study of experiments on and models for water and solute transport in macroporous soils are summarized. It is pointed out that a large number of experiments should be done and observing method improved so that a vast amount of data can be obtained and macropore flow be studied qualitatively and quantitatively, that models can be improved and applied to practice only when the technology for parameter measurement and determination is developed, that new simulating and numerical methods are needed to solve highly nonlinear and unsteady problems in macropore flow, and that the key point for future simulation research should not be deterministic models but stochastic models.
