摘　　要：采用GIS技术对固化污泥的SEM图像进行三维定性与定量微观结构分析。研究结果表明:从固化污泥的3D Scene图像中获取的信息量远远大于SEM图像的信息量,能更真实地反映固化污泥微观结构表面起伏情况;通过GIS技术可以计算三维孔隙率和三维分形维数等微观参数,以及其三维孔隙率和三维分形维数的计算方法是合理的。Qualitative and quantitative microstructure study of the SEM image of solidified sludge was conducted using GIS technology.The results show that information obtained from solidified sludge’s3D Scene image is much more than that from SEM image,which veritably reflects the situation of solidified sludge’s microstructure surface undulation.By using GIS technology,microcosmic parameters like3D porosity and3D fractal dimension can be extracted and the calculation method of3D porosity and3D fractal dimension is reasonable.
