I attempted restructuring the three-dimensional structure of void of soils by using a consecutive soil thin section. Using of soil sample is B horizon of brown forest soil. As for voids of this horizon, packing voids of soil micromorphological description is main. Consecutive soil thin sections were made by using slicing-machine. A interval of soil thin section is about 1 mm thick. Soil voids has been extracted by the image analysis. I obtained the image made binary. This binary image was used. I obtained a three-dimensional image with a personal computer. As the result from three-dimensional structure, discontinuity was clarified to voids. Therefore, voids of this horizon is mainly packing voids. This three-dimensional restructuring method is very effective as for the research method on soil structure.
