[Objective] To provide technical support for desertification control

the effects of grass planting methods on vegetation restoration of moving sand dunes in alpine grasslands were studied.[Methods] On a moving sand dune of Maqu County

Gansu Province

experiments involving different seeding modes

different grass species

and different grass planting modes were conducted to analyze the effects of different grass planting methods on vegetation restoration.[Results] Broadcast seeding and drill seeding had no significant effect on vegetation restoration. Overall

grass species had little effect on vegetation restoration

and it was only necessary for planting Elymus nutans in the vegetation restoration of moving dunes. The planting mode had a significant effect on vegetation restoration. In the second year of grass planting

the height

density

coverage

above-ground biomass fresh weight

and dry weight of grass were significantly increased in paving cow and sheep dung mode compared with no paving cow and sheep dung mode. In the same modes of paving cow and sheep dung

the height and coverage of grass were significantly higher in "cow and sheep dung + no sand barrier grass" mode with a thickness of cow and sheep dung of approximately 2 cm than in "cow and sheep dung + sand barrier grass" mode with a thickness of cow and sheep dung of approximately 1 cm. The grass growth status was positively correlated with soil nutrient and water holding capacity.[Conclusion] "Cow and sheep dung + no sand barrier" grass planting mode was the optimal mode of vegetation restoration of moving dunes in the study area. If the thickness of the cow and sheep dung was approximately 2 cm

it was no longer necessary to set other sand barriers for sand fixation.
