陕西省水土保持所根据各年经验总结出的等高灌木带技术是在坡耕地上,根据地面坡度,每相隔一定间距,沿等高线进行反向坡整地后,栽植2—3行灌木而形成条状灌木丛,用以防止耕地被水力和风力侵蚀的一种水土保持措施。其主要作用是降低风速,防风固沙和改变小地形,拦蓄地面径流和泥沙。此技术主要用于黄土高原地区坡耕地治理。 Shaanxi Provincial Institute of Soil and Water Conservation summarizes the contour shrub technology based on the experience of each year. On the sloping farmland, according to the slope of the ground, The formation of strip bushes to prevent arable land from water and wind erosion as a water and soil conservation measures. Its main role is to reduce wind speed, wind and sand fixation and change the small terrain, intercept ground runoff and sediment. This technology is mainly used for slope farmland management in the Loess Plateau.
