Research on the Technology of Anti-Erosion and Vegetation Promotion for Pisha Sandstone Region in the Middle Yellow River Basin
IOP Conference Series: Earth and Environment
Pisha sandstone region is the most vulnerable and the most dramatic area of soil erosion, and it is also the concentrated source area of the coarse sediment of the Yellow River. It is of great significance to research the anti-erosion and vegetation promotion technology in the Pisha sandstone region. Based on the review of previous research results on soil erosion control technology in Pisha sandstone area, this paper mainly introduces the anti-erosion and vegetation promotion technology in
... n technology in recent years, including the anti-erosion and vegetation promotion material suitable for Pisha sandstone area in the middle Yellow River Basin, the modified dam-building material of Pisha sandstone, and the stereoscopic configuration mode of binary stereoscopic anti-erosion and vegetation promotion measures in Pisha sandstone area. Field monitoring experiments showed that the runoff and sediment yield of the experimental plot were reduced by more than 70% and 91% respectively, which can provide technical support for the harnessing and development of serious soil and water loss areas of Pisha sandstone and the harnessing and development of the Yellow River.
