[Objective] Clarifying the relationship between physical properties and organic-mineral complexes of reclaimed soil was supposed to provide a support for ameliorating the reclaimed soil physical condition.[Methods] This study chose the soil under three patterns of typical artificial vegetation restoration for seven years in Datong Reclamation District of Huainan City

which had been back-filled with coal gangue. Soil physical indictors and formations of organic-mineral complexes were quantified using standard procedures

and their relationship was determined by multivariate statistical analysis.[Results] Soil organic-mineral status and the combined humus varied with different vegetation restoration patterns in the survey region. The stably-combined humus dominated

and it accounted for 41%~67% of combined humus. Vegetation restoration lowered oil bulk density and increased total porosity significantly in contrast with that of natural soil. These effects were more obvious in the mixed plantation pattern of Ailanthus altissima and grass. Soil non-capillary porosity had significantly positive correlations with the amount of organic-mineral complexes and the ratio of tightly-combined humus to combined humus; however

a negative correlation was found of it with the ratio of stably-combined humus to combined humus. Soil capillary porosity was negatively and significantly correlated with the amount of organic-mineral complexes and the ratio of tightly-combined humus to combined humus; and was positive and significantly correlated with the ratio of stably-combined humus to combined humus. Positive association existed between contents of three fractions of soil combined humus

and total porosity and negative correlation it was between the combined contents and low bulk density.[Conclusion] The physical condition showed strong correlations with organic-mineral complexes in reclaimed soils.
