摘　　要：比较了传统的土壤切片的数字图像处理软件与ERDAS IMAGINE 8.5软件的不同,从处理流程、结果精度等几个方面指出了新软件的优越性。利用土壤切片的数字图像,以孔隙面积为基础数据,定量评价小尺度上的土壤孔隙率的变异。结果表明,土壤孔隙率在毫米尺度上存在较为明显的差异,在水头压力下,孔隙率随着深度增加而变大。On the base of the difference of dealing software between the traditional soil pore＇s digital images and ERDAS IMAGINE 8.5, the advantages of the latter are pointed out in the disposing flow and the precision of result. By using the method of digital image, pore areas are treated as basic data and the pore variability in small scale is analyzed. The result showed the evident existences of the variability of porosity in soils on mm-scale. Under the stress of water, pore becomes more and more bigger with the deepness increasing.
