将粒子系统和元球技术从计算机图形学引入到地理学中，结合坡面水蚀遥感信息模型（RSIMWEH），提出了侵蚀体素的概念，在三维空间中动态显示坡面水蚀过程，是对三维GIS理论的新探索，并通过应用证明了其可行性。
Particle system and metaball techniques are introduced from computer graphics to geography.Combined with Remote Sensing Information Model of Water Erosion on Hillslopes(RSIMWEH),the authors put forward the concept of erosion voxel and dynamically display the process of soil erosion by water on hillslopes in 3D space.This is a new probe for 3D GIS theory and the paper proves its feasibility through application.
