Classification and Zoning of Improved Materials of Weathered Redbed Soil in China Based on the Integrity of Mud Skin

Natural redbeds are widely distributed throughout China. Ecological restoration entails implementing measures according to the local conditions and obtaining materials, ensuring ecological environment conservation in a scientific manner. The mud skin of weathered redbed soil is often used control desertification repair slope, its integrity important measure repairing effect. However, most materials for improvement contain harmful chemicals, bear high costs, aggravate environmental pollution. At present, knowledge about different kinds Chinese zones unclear. To solve this problem, we considered naturally as raw material, selected 77 improved tested natural after adding material; then, compared it with no added materials. Then, put forth classification standard discussed driving factors, formulated suitable zoning defined effects on regions results suggested that, soil, nano water-based adhesives were south-western, north-western, south-eastern, north-eastern, northern China can be other well. Starch was least material unsuitable South-West larch tannin extract; wormwood straw South-East modified that not use starch. Thus, our study provides concrete basis regarding effectiveness addressing hazards caused by
