摘 要: 经过我们的多次科考调查:三江源保护区地理位置和生态环境独特、地形地貌复杂,自然环境类型多样,是生物多样性最丰富、最集中的地区,动植物中有许多保护种和特有种;同时,三江源保护区也是生态系统最敏感的地区,近几十年来,由于自然和人类活动的双重作用,生态环境逐渐退化,生物多样性种类和数量锐减,生物多样性保护刻不容缓。只有加强科学管理和生态建设,恢复和重建三江源保护区生态系统和栖息地环境,才能使三江源区生物多样性得到有效保护。 We have investigated the Sanjiangyuan nature reserve many times.There are special geography location and environment, complex landform and physiognomy, many types of environments in the area. It is an zone with abundant biology diversity and protected and endemic species.Meanwhile, it is a sensitive ecosystem. In recent several decades,the environment is becoming degenerated and species diversity and quantity are sharply decreased because of the influences of nature and human activity. It is the time to protect biology diversity. Only do we strengthen scientific management and ecological construction and renew the ecosystem of the Sanjiangyuan nature reserve and the habitat, can we protect its biology diversity.
