The insufficiency of the seed bank in degraded sandy lands limits their natual recovery capablilty. Traditional techniques for vegetation restoration by adding to the seed bank are constrained by difficulties in determining the number and ratio of added species. In response to these issues, researchers have proposed a method of vegetation restoration using donated soil seed banks, which involves transferring topsoil containing a soil seed bank from long-term stable communities with similar vegetation habitats to restore damaged areas.The method has shown good application effects in the restoration of damaged wetlands, grasslands, and forests, but its applicability to restoration of desertification-prone areas has not yet been reported. This study combination of indoor potted plant expriments and simulated rainfall to compare the effects of the donated soil seed bank method from a long-term stable fixed dune on the vegetation restoration of mobile and semi-fixed dunes, and to simulate the impact of rainfall changes on the restoration effects. The results indicate that: 1) Donated soil seed bank significantly increased the number of germinated seeds and aboveground biomass of seedlings in simulated treatments for semi-fixed and mobile dunes, which is beneficial for promoting the succession of mobile and semi-fixed dunes to fixed dunes; 2) The vegetation restoration effect of the donated soil seed bank method is better in semi-fixed dunes than in mobile dunes; 3) Donated soil seed bank can increase the possibility of leapfrog restoration in mobile dunes and accelerate their succession to fixed dunes; 3) small increase or dcrease in rainfall have no significant effact on the number of germinated seeds and aboveground biomass in the recipient area; 4) extreme rainfall can significantly increase the number of germinated seeds and aboveground biomass in the recipient area. In summary, under simulated experimental conditions, the technology of donated soil seed bank can effectively promote the restoration of degraded dune vegetation, and extreme rainfall events have a more significant impact on the restoration effectiveness after implementing donated soil seed banks. This study provides theoretical support for the practical application of donated soil seed banks in the restoration of degraded sandy land vegetation.
