ABSTRACT
The exploitation of coal mineral resources brings convenience and wealth, as well as the damage of ecological environment. This study selected Sandy loessin in the mine-concentrated region, using soil samples with roots, pure soil, and designed roots for soil anti-scouribility experiment. The primary goal of this study was to evaluate the relative contribution of root net-link, soil-root bond, and biochemistry functions, to create soil configuration in soil anti-scouribility. The results showed that root physical consolidation effect is the governing factor, contributing 69.5% in soil reconstruction process of new structural soils. Compared with alfalfa density of 90 plants/m2, physical consolidation effect in the treatment of 360 plants/m2 increased by 12.4%. In addition, the root link function is the key man-ner in a proportion of 79.6% in the physical consolidation effect. Exponential function can well express the relationship between root physical consolidation effect and root surface area density.
