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。
Purple sand shale trench-shaped erosion zone management and development of technical measures to take the main high-altitude plant dams, that is, the use of the last year has been built on the contour of the wind and rock dam planted arborvitae plants, the formation of green contour plants ; Secondly, in the area where the population is small and the land is small, the slopes below 10 ° can be directly exploded into horizontal soil, and after 1 or 2 times of turning to accelerate weathering, the second year spring planting yellow smoke.
