Throughfall is the main component of rainfall redistribution, which affects vegetation growth and soil moisture distribution. Taking the typical tree species in the southern dump of Pingshuo mining area as the research object, the spatial distribution characteristics of throughfall of Pinus tabulaeformis, Robinia pseudoacacia, Euonymus maackii, Caragana microphylla and Elaeagnus multiflora were compared and analyzed by using geostatistical methods and time stability plots. The average throughfall percent from large to small was: Elaeagnus multiflora, Caragana microphylla, Pinus tabulaeformis, Euonymus maackii, Robinia pseudoacacia. The coefficient of variability of throughfall percent from large to small was Euonymus maackii, Elaeagnus multiflora, Caragana microphylla, Pinus tabulaeformis, Robinia pseudoacacia. The throughfall percent of Pinus tabulaeformis, Robinia pseudoacacia, Euonymus maackii, Caragana microphylla and Elaeagnus multiflora increased with the increase of rainfall, and finally reached a steady state, and the coefficient of variability of throughfall percent decreased rapidly with the increase of rainfall, and finally reached a steady state, and the logarithmic function was the best fitting effect. The still of throughfall percent decreased exponentially with the increase of rainfall, and the nugget coefficient increased with the increase of rainfall, indicating that with the increase of rainfall, the throughfall percent tended to be uniform in space, and the spatial heterogeneity caused by random factors gradually increased. Moreover, the throughfall percent of the five tree species was higher than 100% in the middle and outer parts of the plant canopy. The temporal stability of the distribution pattern of throughfall shrubs was higher than that of trees. The canopy near the base and the outer edge of the canopy showed extreme persistence of throughfall. The base near the vegetation was mostly in an extremely dry state, and the outer edge of the canopy was mostly in an extremely wet state. Considering the throughfall percent and its spatial variability, Robinia pseudoacacia was the best choice of vegetation type for reconstruction in soil erosion areas. The throughfall appeared continuously wet at the edge of the vegetation canopy, and some shrubs could be planted to intercept part of the throughfall. These research results could enhance the understanding of the ecological and hydrological process of the mining dump, and provide a theoretical basis for the selection of vegetation for the reconstruction of the mining dump.
