摘 要:紫色砂页岩沟状侵蚀区治理与开发的技术措施主要采取等高定距植物坝,即利用上一年已筑好的等高风化石坝种上乔灌草植物,形成绿色等高植物带;其次是在人多地少的地区,可将10°以下的山坡直接爆破成水平梯土,经过1~2次翻动加速风化后,第二年春种植黄烟。这些措施既达到了控制水土流失的目的,又可增加农民收入,是值得推广的防治方法。The main technical measure for the management and development of purple sand shale erosion area in gully-shape is to adopt living dams with contour fixed space,i.e.to plant arbors,bushes and grasses on the existing contour weathered stone dam which was built in the previous year,forming green contour plant belt;then to build <10° slope hills into leveled terraced fields by using demolitions where has less land and more people and to plant Common Tobacco in spring after 1 ~ 2 times turning up for quick weathering.These measures have not only controlled soil and water loss,but also increased the farmers' income.It is worth popularizing for prevention and control.
