为了明确采煤沉陷区不同植被恢复类型土壤团聚体组成及其稳定性变化，进而筛选出最佳的复垦林型。针对神府-东胜矿区采煤沉陷地设置长柄扁桃、欧李、文冠果3种林型，同时以周边未复垦地作为对照，探究深0～20、20～40 cm土层土壤机械稳定性和水稳定性团聚体组成及稳定性对长期植被复垦的响应规律。结果表明：长柄扁桃、欧李和文冠果复垦提升了深0～20 cm和20～40 cm土层粒级>2 mm、〖JP3〗0.25～2.00 mm粒级机械稳定性和水稳定性团聚体的含量，降低了粒级0.053～0.250 mm〖JP〗和<0.053 mm粒级机械稳定性和水稳定性团聚体的含量；不同复垦林型各土层>0.25 mm机械稳定性团聚体（DR>0.25）、水稳定性团聚体（WR>0.25）分别较对照增加了17.86%～33.36%和12.94%～21.69%；平均重量直径（MWD）、几何平均直径（GMD）较对照样显著增大、分维形数（D）减小；文冠果土壤团聚体MWD和GMD最大、D最小，稳定性最高；0.053～0.250 mm和<0.053 mm粒级团聚体与粒级大于0.25 mm团聚体含量R＞0.25、MWD、GMD均呈极显著负相关。不同植被恢复林型均能促进粒级较小的团聚体向更大粒级团聚体转变，尤其是大于0.25 mm团聚体含量，增加土壤团聚体的稳定性；文冠果林大团聚体含量最高，稳定性最好，植被恢复效果更佳。

In order to identify the soil aggregate composition and stability changes of soil aggregates in different vegetation restoration types in coal mining subsidence areas, and then screen out the best reclaimed forest types. Aiming at the coal mining subsidence land in Shenfu Dongsheng mining area, three forest types of Amygdalus pedunculata, Cerasus humilis, and Xanthoceras sorbifolia were set up in the coal mining subsidence of this area, and the surrounding unreclaimed land was used as a control to explore the response of soil mechanical stability and water stability aggregate composition and stability in 0-20 cm and 20-40 cm soil layers to long-term vegetation reclamation. The results showed that the reclamation of Amygdalus pedunculata, Cerasus humilis, and Xanthoceras sorbifolia increased the content of mechanical stability and water-stable aggregates of 0-20 cm and 20-40 cm soil layers>2 mm and 0.25-2.00 mm, and decreased the content of mechanical stability and water-stable aggregates of 0.053-0.250 mm and<0.053 mm soil layers; the mechanical stability aggregates (DR>0.25) and water stability aggregates (WR>0.25) in different soil layers of different reclaimed forest types increased by 17.86%—33.36% and 12.94%—21.69% respectively compared with the control; the mean weight diameter (MWD) and geometric mean diameter (GMD) increased significantly larger than the control plot, and the number of fractal dimensions (D) decreased compared with the control. The MWD and GMD of Xanthoceras sorbifolia soil aggregates were the largest,, the D value was the smallest, and the stability was the highest; 0.053—0.250 mm and<0.053 mm aggregates were negatively correlated with R>0.25, MWD and GMD. The main conclusion is that different types of vegetation restoration can promote the transformation of aggregates of smaller size to larger size aggregates, especially the aggregate content greater than 0.25 mm, which increases the stability of soil aggregates; Xanthoceras sorbifolia forest has the highest macroaggregate content, the best stability and better vegetation restoration effect.
