摘　　要：该文通过研究全耕翻种草和免耕补播对祁连山黑河上游"黑土滩"退化草地的影响,表明全耕翻种草和免耕补播能显著提高草地植物的盖度、高度、优良牧草量和地上植物量(P<0.05),提高优良牧草所占比例,降低草地表层土壤容重,提高退化草地的地下植物量,是恢复祁连山黑河上游退化天然草地的有效途径,并且全耕翻种草对植物生物量和草地生产力的提升更大,而免耕补播对保护原有生态环境的物种多样性更好。The effect of full ploughing up and no-till reseeding on Hetutan degraded grassland in Heihe river upstream in Qilian Mountains was studied. The resulted that full ploughing up and no-till reseeding can significantly improve the coverage, height of plant,excellent plant and the aboveground biomass of plants（P 〈0.05）, increase the proportion of fine forage grass, reduce the soil bulk density of grassland surface, increase underground biomass of degraded grassland, which is an effective way to restore the degraded natural grassland in Heihe river upstream in Qilian Mountains, and full ploughing up can improve plant biomass and grassland productivity, no-till seeding can protect the species diversity of original ecological environment.
