In order to investigate the function of water conservation in lands of different using types in the dump reclamation area, using field double-ring infiltration method and indoor soil physical and chemical analysis, this paper systematically investigated soil infiltration characteristics and their influencing factors under different utilization types (arbor, shrub, farmland, and grassland) in the dump reclamation area. The results indicated that infiltration rates, stable infiltration rate, and cumulative infiltration under different utilization types in the dump reclamation area showed the following order of arbor > shrub > farmland > grassland; The goodness of fit of the infiltrating processes were different under different utilization types in the dump reclamation area, with the average value being 0.926, 0.908, and 0.905 for the G-P model, the Kastiakov model, and the Horton model, respectively. The relative error of the G-P model was 79.2%-123.69%, it was closed to the actual process of soil infiltration in the reclaimed area, and could be used as the prediction model of soil infiltration process in the reclaimed area. The initial infiltration rate under different utilization types in the dump reclamation area had significantly positive correlations with non-capillary porosity, and stable infiltration rate, while cumulative infiltration had significantly positive correlations with non-capillary porosity, gravel content, root length density, and root surface area density. Principal component analysis showed that soil infiltration capacity followed the order of arbor > shrub > farmland > grassland. The initial infiltration rate, stable infiltration rate, 14-min infiltration rate, and cumulative infiltration together accounted for 99.047% of the principal component variance, and described the soil infiltration capacity well.
