摘要
Sanjiangyuan is known as“China’s water tower”and“germplasm bank of alpine organisms.”Sanjiangyuan National Nature Reserve,located in the heart of the Qinghai-Tibet Plateau,is the largest nature reserve in China.Sanjiangyuan(which literally means origin of three rivers)is so called because the Yangtze River,the Yellow River,and the Lancang River all originate here.It is an important ecological shield and water conservation area in China and even all of Asia.
三江源素有“中国水塔”、“高寒生物种质资源库”之称。中国最大的自然环境保护区—三江源自然保护区—位于青藏高原腹地,因长江、黄河和澜沧江发源于此而得名,是中国乃至亚洲重要的生态屏障和水源涵养区。20世纪中期以来,受气候变化和人类活动等因素影响,三江源地区生态系统遭到严重的破坏。
