摘　　要：在玛曲县沙化草原人工种草生态修复工作中,典型存在沙地种草成活率低的瓶颈问题。该试验通过采用实践应用的“草方格+覆土+有机肥+种草”本土方法治理模式,在沙地对不同覆土厚度对种草效果进行了试验探索,总结出在当地沙地最为经济实用的覆土厚度值,为沙化治理提供借鉴和推广依据。In the ecological restoration work of artificial grass planting in the desertified grassland of Maqu County, there is a typical bottleneck problem of low survival rate of grass planting in sandy land. By adopting the local governance model of "grass squares + covering soil + organic fertilizer + planting grass" in practice, the experiment explored the effects of different covering soil thicknesses on grass planting in the sandy land, and concluded that the local sandy land is the most economical and practical. The thickness value of soil covering can provide reference and promotion basis for desertification control.
