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 Using soil slices and digital image technology, the pore structure of soil in different parts of the gentle hillside (top, slope and bottom) of grape plantations was primarily studied. The results show that the pore area decreases with the increase of depth, and the pore structure is dominated by small pores with diameter less than 1 mm. With the increase of depth, the specific gravity of small pores increases and the pore structures of different parts have certain differences. Necessity of soil and water conservation measures
