| 摘 要： | 近年来,青藏高原草地生态环境安全引起人们的高度重视,但是其生态环境仍处于不断恶化的状态。本文分析了青藏高原高寒草地生态系统的草地退化现状、退化因素和改良技术研究等,并针对其现状和恢复目标,为高寒草地生态系统和草地畜牧业的可持续发展提出了一些建议:加强高寒草地生态系统的基础研究,建立综合的草地改良和恢复技术体系,加强草地生态系统的管理,建立合理的草地放牧制度体系,并建立高效的饲草供应人工草地,在退化草地上建立集约化的高效社区模式草地畜牧业体系,改变退化草地生态功能,是实现退化高寒草地生态恢复、生物多样性保护和经济可持续发展的最佳措施。

| Abstract: | In recent decades, the grassland ecological environments of the Qinghai-Tibetan Plateau were degraded continuously, which have been paid high attention by human beings. The actuality, the causes and the improvement techniques of grassland degradation in alpine meadow of the Qinghai-Tibetan Plateau China and the ecological restoration measures and aims were discussed in this paper. The authors put forward some measurements and advices for the protection and construction of the meadow ecosystem and its sustainable development of alpine meadow grassland ecosystem of the Qinghai-Tibetan Plateau: strengthening basic researches of alpine meadow grassland ecosystem, establishing synthetical grassland improvement and restoration techniques systems, strengthening researches of grassland ecosystem management and reasonable grazing systems and establishing effective artificial grassland for guarantee of forage grass, establishing intensive and effective community-mode grassland stockbreeding systems, which will change and restore grassland ecological function. These measurements are prerequisite for ecological restoration, biodiversity protection and pastoral economy sustainable development of the Qinghai-Tibetan Plateau. |
