中文摘要：
土壤作为被研究的对象，其孔隙特征及孔隙分布是研究基本而重要的内容。图像技术的发展能够较易获得μm-mm间距尺度的孔隙。通过研究傅立叶变换及滤波技术，结合实测土壤孔隙率，较准确的识别孔隙并得到土壤-孔隙二值图像。土壤孔隙分形维数反映了土壤孔隙与固体颗粒接触界限的不规则性。基于土壤-孔隙二值图像的孔隙分形维数分析表明：土壤孔隙的形状及排列分布方式虽然非常复杂，图像分析方法能够较准确和稳定的测量土壤孔隙轮廓线分形维数。
英文摘要：
The pore characteristics and distribution of soil has been the basic and important subject of investigation. With the development of digital image technology, it＇s easy to obtain images of soil-pore between micron and millimeter scale. In this study, we relatively accurately recognize the pore and acquire soil-pore binary images by Fast Fourier Transform （FIT） and filter technique, combined with actual soil porosity. The soil-pore fractal dimension depicts the irregular and rugged soil-pore interface indicates the boundaries between soil pores and particles. The fractal dimension research of image analysis method can be used to measure accurately and steadily the fractal dimentions of soil pore profile, though pore shape and pore-size distribution pattern are extremely complicated.
