摘要： 河流故道区梨树根系分布特征的研究表明：梨树根系垂直方向集中分布在50~100 cm，水平方向在100~150cm土体中。其中吸收根根量垂直分布集中在50~100cm，水平方向在150~200 cm土层内。该区砂壤土中9年生梨树根系水平生长优于向下伸长。

Abstract: The root of pear in river ancient channel mainly distributed in the 50~100 cm vertical depth and 100~150cm horizontal width in soil layer. And the absorption root of pear in river ancient channel mainly distributed in the 50~100 cm vertical depth and 150~200 cm horizontal width in soil layer. In sandy soil of this area, the growth of root of mature tree in horizontal exceeded that in vertical. It is opposite with the convention.
