Zusammenfassung: | The invention belongs to the field of grassland restoration, and discloses a degraded grassland restoration method, which specifically comprises the following steps: 1) identifying different sedimentary facies structure characteristics of a vertical stratum in a research area; 2) researching characteristics of grassland degradation indicating plants in the research area, and dividing degradation degrees; 3) analyzing a grassland degeneration geological action mechanism, including analyzing the influence of landform on distribution of the herba euphorbiae lantu and a synergistic or antagonistic main control factor of the influence of sedimentary facies change on plant growth indication; 4) constructing a grassland degradation model constrained by sedimentary facies under similar habitat conditions based on geoscience concept; 5) indoor grass seed screening based on the drought resistance coefficient; and 6) planting in the mixed sowing groove in the demonstration area, and providing a degraded grassland compre |
