研究了不同试验因素 (包括图像分辨率、土壤切片定向性、分析区域大小等 )对孔隙结构图像分析结果的影响以及试验误差 ,并简要介绍了用于分析土壤孔隙结构的土壤切片及数字图像的制备技术。结果表明 :不同试验因素对分析结果均会产生一定的影响 ,试验误差约在 1 0 %。这表明同一研究中应保持试验条件的相对一致以保证分析结果的可靠性和可比性 The effects of different experimental factors (including image resolution, orientation of soil slices, size of analysis area, etc.) on the results of pore structure image analysis and experimental errors were studied. Soil slices and digital images for analyzing soil pore structure were briefly introduced Preparation technology. The results show that: different experimental factors will have some impact on the analysis results, the experimental error of about 10%. This shows that the same study should be relatively consistent test conditions to ensure the reliability and comparability of analytical results
