利用数字图像分析土壤表面裂隙的方向分布

摘要

利用二维数字图像方法研究了在土壤干燥过程中表面裂隙方向分布的演化状况。结果表明，随着干燥过程的持续，裂隙的长度、宽度、面积和分数维均趋于增加，但裂隙的方向分布则逐渐趋向均匀。%This paper studied the development of the orientation of soil surface crack during the soil drying process using digital image technique, and the results showed that with drying continued, the length, width, area and fractal dimension of the soil surface crack increased, and the orientation of the soil surface crack tended to be more homogeneous.
