摘　　要：青藏高原是我国牦牛的主产区，但近年来黑土型退化草地的发生与发展直接威胁着我国牦牛业的发展。通过对退化草地的调查分析，认为不合理的放牧制度是引起草地退化的主要原因，草地退化又引起牦牛生产力的下降，据此提出了通过建立人工、半人工草地和加强牦牛的科学饲养管理、改善本地区生产环境、保持牦牛—高寒草甸系统持续发展的设想。inghai-Tibetan Plateau is the main area for yak production in China. It is threatened by the increase of black soil deterioration. Based upon the survey for the deteriorated grassland, we concluded that unreasonable grazing system was the major factor which caused grassland deterioration and yak production decrease. Attentive strategy for sustainable development of yak-alpine meadow system was presented in this paper through analyzing research results, which was to establish artificial pastures, or enhanced yak management scientifically and improve local environment.
