| 摘 要： | 生态系统长期定位观测是对生态系统研究的重要手段,通过在典型自然或人工生态系统地段建立长期定位观测设施,对生态系统的组成、结构、生物生产力、养分循环、水循环和能量平衡等在自然状态或人为干扰下的变化过程进行长期连续观测,以阐明生态系统发生、发展、演替的内在机制。单个站点的长期定位观测、实验和研究往往具有其局限性,难以揭示更普遍性的规律。多站联合,从站到网的模式成为生态定位观测发展的必然趋势。20世纪70年代,生态定位观测研究站的网络化、全球化迅速发展。生态系统定位观测研究网络是开展生态系统长期定位观测的重要平台,为全球环境变化和陆地生态系统相互作用关系的研究提供了重要手段。为全面了解我国陆地生态系统定位观测研究网络的发展现状,本文从发展情况、取得成果等方面重点介绍我国陆地生态系统定位观测研究的三个主要网络:中国陆地生态系统定位观测研究站网(CTERN)、中国生态系统研究网络(CERN)和国家生态系统观测研究网络(CNERN),并对我国陆地生态系统观测研究网络存在的问题,发展趋势进行了探讨。

| Abstract: | Long-term positioning observation of ecosystems is an important means of ecosystem research. By establishing longterm positioning observation facilities in typical natural or artificial ecosystem areas,Long-term and continuous observations of changes in the composition,structure,biological productivity,nutrient cycle,water cycle,and energy balance of ecosystems under natural conditions or human interference are carried out to clarify the underlying mechanisms of ecosystem occurrence,development,and succession. Long-term positioning observations,experiments and research of individual stations often have their limitations and it is difficult to reveal patterns that are more general. The multi-station joint and slave-to-network model has become an inevitable trend in the development of ecological positioning observation. In the 1970 s,the network and globalization of ecological positioning observation stations developed rapidly. The ecosystem positioning observation network is an important platform for long-term ecosystem positioning observation and provides an important means for the study of the interaction between global environmental change and terrestrial ecosystems. In order to comprehensively understand the development status of China’s terrestrial ecosystem positioning observation network,This paper mainly introduces the China Terrestrial Ecosystem Research Network(CTERN),Chinese Ecosystem Research network(CERN)and National Ecosystem Research Network of China CNERN)and discussed the problems and development trends of China’s terrestrial ecosystem observation and research network. |
