本文在现有坡面水土流失建模理论和可视化方法的基础上，将坡面径流与侵蚀模型分为形式逻辑计算模型和辩证计算模型，如RSIMWEH（Remote Sensing Information Model of Water Erosion on Hillslopes）。在将计算机图形学领域的最新技术（粒子系统和元球）与RSIMWEH相结合的过程中，我们提出了侵蚀体素的概念。利用该方法，我们已经成功地模拟了不规则的动态模糊对象和侵蚀体素为基础的过程中的坡面水蚀在三维空间。
Based on existing modelling theory and the visualization methodology of water erosion on hillslopes, this paper classifies models of overland flow and erosion as formal logic computational models and dialectical computational models, e.g. RSIMWEH (Remote Sensing Information Model of Water Erosion on Hillslopes). During the process of combining the latest technologies (particle systems and metaballs, which are based on the field of computer graphics) with RSIMWEH, we put forward the conception of erosion voxel, which is governed by the laws of geography. Using our method, we have successfully simulated irregular dynamic fuzzy objects and the erosion-voxel-based process of water erosion on hillslopes in 3D space.
