英文摘要	Soil moisture is generally considered to be a major limiting factor for root growth of shrubs in the arid and semi-arid regions. However, as a typical shrub species, the correlation between root distribution and soil moisture of Caragana microphylla has not been well investigated. Ground-penetrating radar (GPR) has the advantage of acquiring locations of roots quickly and simply, therefore, we used GPR to acquire locations of roots in the quadrat of 30m*30m, and soil moisture data was acquired by soil drilling method. After processing data, we analyzed the correlation between root density and soil moisture in vertical and horizontal directions. Following conclusions were obtained through vertical and horizontal analysis: In the vertical direction, root density was positively correlated with soil moisture, but the soil moisture was lower in the dense absorbing roots' distribution region, even the preferential flow could enrich soil moisture. Root density and soil moisture also had a positive correlation in horizontal direction, but they were inversely related in the region of dense absorbing roots.
