美国长期生态学研究(Long-Term Ecological R e-s e a r c h,L T E R)项目是由美国国家科学基金会(National Science Foundation,NSF)资助,于1980年正式启动。LTER是世界上第一个以长期生态学现象为主要研究对象的研究网络,是建立最早、代表生态系统类型最多(目前共有代表森林、草地、农田、湖泊、海岸、荒漠、极地冻原和城市等生态类型的26个实验站)、设备最完善的国家尺度长期生态研究网络,其建成与完善对于其他长期生态研究网络的发展具有示范作用。2012年1月底,美国国家科学基金会(NSF)生物科学咨询委员会发布了由长期生态学研
The Long-Term Ecological Re-ergeric Project, funded by the National Science Foundation (NSF), was officially launched in 1980. LTER is the first research network in the world that focuses on long-term ecological phenomena. It was first established and represented the largest number of ecosystems (currently representing forests, grasslands, farmlands, lakes, coasts, deserts, polar tundra and cities Etc.), and the most complete national long-term ecological research network with the most complete equipment. Its establishment and perfection have an exemplary role in the development of other long-term ecological research networks. The end of January 2012, the National Science Foundation (NSF) Biological Sciences Advisory Committee released by the long-term ecology research
