Abstract:

Eddy Covariance technique (EC) achieves the direct measurement of system functions and processes such as plant productivity, energy balance, and greenhouse gas exchange at ecosystem scale. Coordinated observation through the global flux observation network represents a breakthrough from the observation of ecological phenomena and factors to the measurement of changes in functions of the global ecosystem. This paper first reviews the foundation and development of the Chinese terrestrial ecosystem flux observation and research network (ChinaFLUX). It then systematically introduces the scientific objectives, design concept, measurement system, standardization of observed data, and long-term data accumulation of the network. The paper also assesses the main progresses in research of terrestrial carbon-water-nitrogen budgets, environmental responses of the coupled ecosystem carbon-nitrogen-water cycles, and the spatiotemporal patterns of ecosystem carbon fluxes and mechanisms. Based on an analysis of the trend of development and emerging missions of the global flux network, this paper proposes the directions, key scientific questions and emphases of research of ChinaFLUX to provide references for the development of flux observation and research in China.
