西藏生态安全屏障生态监测网络体系建设进展

Development progress of ecological monitoring network for ecological security barrier in Tibet

西藏作为世界上独特的环境地域单元,是全球高海拔生物多样性最丰富的区域,在全球生物多样性保护中具有重要地位,也是世界上海拔最高的高原湖沼分布区和世界上山地冰川最发育的地区,有“中华水塔”之称,是我国重要的生态安全屏障。经国务院批准,国家发展改革委于2009年发布了《西藏生态安全屏障保护与建设规划(2008—2030年)》。基于该规划,西藏自治区开启了西藏生态安全屏障生态监测网络建设工作,建成了由1个生态监测中心、10个生态监测站和100个监测样点组成的生态安全屏障生态监测网络体系,为西藏生态安全屏障保护与建设打下了良好的基础。西藏生态监测网络的不断完善和平稳运行,必将在西藏生态安全屏障建设与监管、揭示环境变化机理、准确把握全球气候变化和人类活动对青藏高原的影响等方面发挥重要作用。

Tibet is regard as one of the Chinese important ecological security barriers.As one of the regions with special ecological and environmental feature and having abundant biological diversity in the world,Tibet occupies an important place in the global biological diversity protection.Tibet is also known as the Water Tower of China,with more distribution of plateau lakes and mountain glacier,where several rivers rise.Approved by the State Council,National Development and Reform Commission issued the Tibet Ecological Security Barrier Protection and Construction Plan(2008—2030)in 2009.Supported by the Plan,the construction of Tibet ecological monitoring network for ecological security barrier started up.So far,the ecological monitoring network with one ecological monitoring center,ten ecological monitoring stations and one hundred ecological monitoring sample plots were completed.The continuous improvement and smooth operation of the ecological monitoring network in Tibet will certainly play an important role in the construction of ecological monitoring network for ecological security barrier in Tibet,revealing the mechanism of environmental change,and accurately understanding the impact of global climate change and human activities on the Tibetan Plateau.
