Abstract: Grassland ecosystem is not only an important natural security barrier of natural system,but also the key support of animal husbandry development. The ecological quality of grassland in the upper reaches of the Yellow River is related to the ecological protection and regional sustainable development of the whole Yellow River Basin. However,in recent years,the grassland ecological environment in the upper reaches of the Yellow River has evolved in a direction that is not conducive to human development. Grassland degradation has accelerated the process of land desertification. At the same time,it has caused natural disasters and river cutoff,which has restricted the healthy and stable development of regional economy. In this paper,the present situation,causes and main characteristics of grassland degradation in important water conservation areas in the upper reaches of the Yellow River were summarized. The technical model of grassland ecological function improvement and grassland adaptive management mechanism were put forward,and the new technologies of grassland restoration and management in the future were prospected. The purpose of this study was to provide theoretical and technical support for ecological restoration and governance of typical water conservation areas such as Sanjiangyuan,Qilian Mountain and Gannan,so as to provide scientific reference for effectively promoting ecological protection and high-quality development of the Yellow River Basin and helping the country to build a sound ecological security system.

摘要: 草地生态系统不仅是自然系统重要的天然安全屏障,也是畜牧业发展的关键依托。黄河上游草地生态质量关系到整个黄河流域的生态保护和区域可持续发展。然而,近年来黄河上游草地生态环境向着不利于人类发展的方向演化,草地退化问题日趋严重,加速了土地荒漠化进程,同时引发自然灾害、河流断流等问题,制约了地区经济健康稳定的发展。本文综述了黄河上游重要水源涵养区域草地退化现状、成因和草地退化的主要特征,提出了草地生态功能提升技术模式及草地适应性管理机制,并对未来草地恢复治理新技术进行了展望,旨在为三江源、祁连山和甘南等典型水源涵养区的生态恢复和治理提供理论和技术支撑,以期对有效推动黄河流域生态保护和高质量发展及助力国家构建完善的生态安全体系提供科学参考。
