Abstract [Background] With the development and utilization of mineral resources, a series of eco-environmental problems have emerged. Land reclamation and vegetation restoration are the main measures for ecological restoration and reconstruction in mining areas. Soil infiltration is an important hydrological parameter to evaluate the water conservation capacity of soil. The study on soil infiltration characteristics and its influencing factors of different vegetation in the reclamation area is helpful to understand the improvement of soil texture by different vegetation in the mining area, and has certain guiding significance for the prevention and control of soil erosion and ecological construction. [Methods] In order to reveal the difference of soil water infiltration characteristics and its influencing factors of different land use types in reclamation area, taking four kinds of artificial restoration of vegetation (Populus woodland, Amorpha fruticosa woodland, reclaimed land and grassland) in the coal gangue reclamation area of Shanxi Yang Coal Group as the research object, the ring knife method was used to determine the soil water infiltration process of different land use types, and the correlation between soil density, soil moisture content, soil porosity, mechanical composition, water-stable aggregates and organic matter content and infiltration performance were explored through the main component analysis. [Results] 1) Compared with grassland, the soil total porosity increased by 0.71%-14.45%, the organic matter content increased by 77.67%-136.89%, and the soil density decreased by 0.65%-14.37% among Populus woodland, A. fruticosa woodland and reclaimed land in the reclaimed area; the initial infiltration rate and the steady infiltration rate were shown as Populus woodland > A. fruticosa woodland > reclaimed land > grassland, and the soil infiltration rate under the same land use type decreased with the increase of soil layer thickness. 2) The fitting of the soil infiltration process to obtain a common empirical equation was the best model to describe the soil infiltration process in this area, with a coefficient between 0.961 and 0.996, and Pearson correlation analysis showed that the soil initial infiltration rate and the steady infiltration rate were significantly and negatively correlated with the soil density (P<0.01), and the infiltration rate was significantly and positively correlated with the total porosity and organic matter content (P<0.05). 3) Principal component analysis showed that soil water-stable aggregates, porosity, mechanical composition and organic matter content were the four main factors affecting soil permeability in the reclamation area, and the cumulative contribution rate of the four was 87.760%. [Conclusions] The arbor-bush reclamation model has a strong soil water infiltration capacity, and its effect on improving soil texture is better than that of grassland reclamation model. In addition, the infiltration performance is closely related to the composition of water-stable aggregates, porosity, mechanical composition and organic matter content. The research results may provide reference for the selection of soil and water conservation tree species in reclamation area.
