通过实地调查、座谈、交流和对牧民的访问,以及对三江源区东北部4县生态环境现状、草地退化原因分析,认为该区草地已呈现全面退化的态势.长期超载过牧是导致三江源区草地退化的主要驱动力,害鼠的孳生蔓延、冻溶、水蚀、风蚀等条件是促进草地退化的辅助因素.人类活动和全球气候变暖的共同作用加速了草地退化的进程.在分析此现状的基础上提出了三江源东北部4县生态保护和可持续发展的策略和建议.
通過實地調查、座談、交流和對牧民的訪問,以及對三江源區東北部4縣生態環境現狀、草地退化原因分析,認為該區草地已呈現全麵退化的態勢.長期超載過牧是導緻三江源區草地退化的主要驅動力,害鼠的孳生蔓延、凍溶、水蝕、風蝕等條件是促進草地退化的輔助因素.人類活動和全毬氣候變暖的共同作用加速瞭草地退化的進程.在分析此現狀的基礎上提齣瞭三江源東北部4縣生態保護和可持續髮展的策略和建議.

A conclusion for the status of eco-environment of Yangtze, Yellow and Yalu Tsangpo rivers source region was obtained after studying by field investigation and interview to local herdsmen. Nowadays, the grassland has degraded entirely. The main reason is overgrazing for long-terms, followed by rats, freezing and thawing, and erosions by water and wind. Besides, human activities and global warming promote the speed of degradation. Strategies and some advices were proposed for protecting ecological system and sustainable development for four counties of this region.
