Abstract

The erosion gully is serious in black soil area of Northeast China and the study of gully restoration is less. In this paper, based on the reconstructed soil, coal gangue was used to filling and cover topsoil on coal gangue to conserve soil and water. To explore the reconstructed soil structural change on properties, the hydraulic and physicochemical parameters of 36 combined treatments with coal gangue and topsoil of different sizes and thicknesses were carried out in the soil column for the experiment. The variations of infiltration, soil water storage capacity (SWSC), and physical and chemical properties under the treatments were discussed. The results showed that coal gangue thickness of reconstructed soil had influence the infiltration rate and cumulative infiltration. The Kostiakov model is most suitably applied to reconstructed soil infiltration. The SWSCs indicated that soil thickness determined the SWSCs, and the interaction between large-sized coal gangue and topsoil thickness had a significant effect on MRWSC. The soil layer was positively correlated with soil nutrients, and coal gangue layer has contributed to reduce the fertility loss. Coal gangue had a significant effect on TP, soil shrinkage and DIR, which is beneficial to reconstructed soil stability and surface water–groundwater conversion. The coal gangue reconstructed soil structure contributed to gully restoration which the large-sized coal gangue of 50 cm thickness, small-sized coal gangue of 50–60 cm thickness and topsoil of 50–70 cm thickness should be used to fill and repaired erosion gullies.
