Problems solved by technology
However, in the entire Liangmaoding-ditch slope-ditch system of Pisha Sandstone, the erosion caused by surface runoff, source erosion, and sediment transport are inseparable.
At present, the ditch slopes are seriously exposed, and due to wind erosion, water erosion, gravity erosion, etc., there are often large-scale arsenic sandstone collapses, and there is no good economic and reasonable treatment method; and the ditch is a rainwater collection place, and the water flow often carries a large amount of water. Sediment flows away, but cannot form an effective interception, resulting in soil erosion
There are no engineering measures in the ditch with a small confluence area, and the large check dam at the mouth cannot be used for a long time due to the characteristics of the local arsenic sandstone
[0004] The Chinese invention patent application with the application number "201510767480.9" discloses "a binary three-dimensional configuration mode for anti-corrosion and growth promotion suitable for small sandstone watersheds", which uses planting vegetation, spraying W-OH series polymer curing materials, A variety of technical means such as laying flexible grids and setting rolling dams have made some progress in the comprehensive treatment of small sandstone watersheds, but there are still defects such as not being systematic enough, the treatment effect is still not good, and the built ecology is fragile and easy to collapse.
[0005] The Chinese invention patent with the patent number "201410011052.9" discloses "a method for treating slopes of arsenic sandstone", which adopts the method of separately treating slopes with different slopes, and has made some progress in slope management, but its The overall soil and water loss problem in the tributary ditch watershed has not yet been resolved

Embodiment
[0037]This example takes a small watershed of Pisha sandstone in Ordos, Inner Mongolia as the research object. Governance of this small watershed involves several steps. First, fully investigate the basic situation of the small watershed in the first year, investigate and record the basic characteristics of the small watershed, such as topography, channel direction, watershed area, vegetation growth, shady and sunny slopes, and channel gradient. The construction of two typical all-slope residential areas will provide basic information for the construction in the second year. Residential quarters are generally constructed as two side-by-side residential quarters, enclosed by economically feasible steel plates. The width of the plots is generally 5 meters wide, and the slope and length of the plots are implemented according to the actual length of a typical slope, extending about 5 meters outward at the top of the slope. There are two runoff collection barrels at the bottom of...

Abstract
The invention belongs to the field of water and soil treatment technologies for soft rock regions, and particularly provides a biomass-material bi-component coupling comprehensive treatment system for river basins in branch gullies with soft rock. The biomass-material bi-component coupling comprehensive treatment system comprises six pieces of spatial engineering and spatial vegetation systems. Residue retaining walls, check dams and silt dams in the six pieces of spatial engineering are made of anticorrosion and growth promotion W-OH materials which are modification materials. The invention further correspondingly provides a biomass-material bi-component coupling comprehensive treatment method for comprehensively treating the river basins in the branch gullies with the soft rock by the aid of the biomass-material bi-component coupling comprehensive treatment system. The biomass-material bi-component coupling comprehensive treatment system and the biomass-material bi-component coupling comprehensive treatment method have the advantages that vegetation organism and the anticorrosion and growth promotion materials are combined with one another, a systematic scheme for solving the problem of water and soil loss of existing river basins in existing branch gullies with soft rock can be ultimately formed by the aid of the vegetation biomass, the anticorrosion and growth promotion materials and spatial engineering technologies, and stable, efficient and omni-directional comprehensive treatment effects can be realized.
Description
technical field [0001] The invention belongs to the technical field of water and soil control in Pisha sandstone area, and specifically relates to a biological-material binary coupling comprehensive treatment method and system for Pisha sandstone tributary ditch watershed. Background technique [0002] Most of the large amount of sediment deposited in the lower reaches of the Yellow River comes from the 18,800 square kilometers of the concentrated source area of the Yellow River's coarse sediment, mainly covering the Pisha sandstone area of the Ordos Plateau in Inner Mongolia. This area is a special landform structure, red and white , mainly distributed in the area centered on the border area of Shanxi, Shaanxi and Mongolia. Due to the bare surface, coupled with the interaction of water erosion, wind erosion and gravity erosion, the local extremely serious soil erosion has become the main source of coarse sand in the middle reaches of the Yellow River. When there is n...
