摘要

以重庆市江津区10和20a林龄的柑橘地为研究对象

应用优先流染色法和室内图像提取技术

土壤水分穿透曲线及Poiseulle方程综合分析土壤大孔隙与优先流的关系。结果表明

大孔隙使染色区的水分渗透速率较非染色区提高了1.48倍以上。柑橘地大孔隙孔径范围在0.3～1.7mm

半径大于0.7mm的土壤大孔隙是形成优先流路径的主要孔径范围。

Abstract

The relationship between soil macropore and preferential flow was analyzed in different citrus land in Jiangjin District of Chongqing City using brilliant blue dye method with image processing techniques

water breakthrough curve

and the Poiseulle equation.The results showed that the steady effluent rate of the dye-stained area was 1.48 times higher than that of the dye-unstained area.The radii of soil macropores ranged from 0.3 mm to 1.7 mm.The path of preferential flows were mainly found in the macropores with radii larger than 0.7 mm.
