| 摘 要： | 分别对南京和聊城土壤含有各种大孔隙的原状土柱以及含有一个已知直径大孔隙的填充土柱进行CT扫描实验，简单CT扫描原理和过程，对CT图像进行处理，得到两种土壤大孔隙横向与纵向的分布，分析比较它们的不同，结果表明不同土壤由于其形成机理和存在条件（例如气候和植被）的不同，大孔隙的分布各不相同。

| Abstract: | Nanjing and Liaocheng Undisturbed soil cores that have many macropores and disturbed soil cores that have one macropore (its diameter is known) are probed by CT respectively. The transverse and longitudinal distribution of macropores in the two soils is characterized by dealing with CT scanning images. Results from analyzing and comparing two distributions indicate that macropores distributions are different because of soil forming mechanism and existing condition. |
