| 摘 要： | 利用土壤切片及数字图像技术 ,初步研究了葡萄种植园低丘缓坡不同部位 (坡顶、坡中和坡底 )土壤的孔隙结构特征。结果表明 :孔隙面积随着深度的增加而减小 ,孔隙构成以直径小于 1mm的小孔隙为主 ,且随着深度增加小孔隙比重增加 ,不同部位孔隙结构具有一定的差异 ,这也说明了采取水土保持措施的必要性 |
| 关 键 词： | 孔隙结构 缓坡不同部位 土壤切片及数字图像 |

| Abstract: | We primarily studied the characteristics of soil Pore strcture at various slope places of a vineyard in a low hill area by using the techniques of soil sections and digital images,and the results showed that:pore areas decreased with the increase of soil depth,the diameter of the dominating pores were smaller than 1 mm,whose proportion increased with the increase of soil depth,differences existed in pore structure among soil at various locations of the low-hill,and those results also showed the necessity of countermeasures for water and soil conservation in these vineyards. |
| Keywords: | Pore structure Various locations in a slope Soil sections and digital images |
