亚洲作为FLUXNET的重要组成部分，由于其地域辽阔、气候类型复杂、植被多样性等特点，日益成为全球碳研究的热点。目前亚洲三个区域通量观测网络（AsiaFlux、KoFlux和ChinaFLUX）共有54个通量观测站点，覆盖热带雨林、万年青阔叶林、针阔混交林、灌丛、草地、高山草甸和农田生态系统，纬度分布范围为2°N至63°N。本文主要利用涡度相关技术对生物圈与大气之间长期、连续的CO2、水汽和能量通量进行测量，以（1）定量和比较不同生态系统之间的碳、水和能量收支，（2）定量分析生态系统碳、水和能量通量的环境和生物控制机制，（3）验证土壤-植被-大气模型，（4）研究土壤-植被-大气模型的有效性。为陆地生态系统碳循环和水循环的综合研究服务。近几十年来，亚洲通量研究界在通量测量、生态系统通量格局、模拟和尺度转换等理论和技术方面取得了很大进展。ChinaFLUX的成立极大地填补了欧亚大陆通量观测研究的差距。为进一步推动通量测量与研究，促进数据共享，提高数据质量，有必要建立复杂地形下通量估算与评价的方法体系，开展通量测量、稳定同位素测量、遥感观测和GIS技术相结合的综合研究。它还要求在亚太地区建立亚洲通量网络联合委员会，以便通过支持项目科学家、讲习班和访问科学家，促进合作和交流想法和数据。中国科学出版社2005年版权所有。
As an important component of FLUXNET, Asia is increasingly becoming the hotspot in global carbon research for its vast territory, complex climate type and vegetation diversity. The present three regional flux observation networks in Asia (i.e. AsiaFlux, KoFlux and ChinaFLUX) have 54 flux observation sites altogether, covering tropic rainforest, evergreen broad-leaved forest, broad-leaved and coniferous mixed forest, shrubland, grassland, alpine meadow and cropland ecosystems with a latitudinal distribution from 2°N to 63°N. Long-term and continuous fluxes of carbon dioxide, water vapor and energy between the biosphere and atmosphere are mainly measured with eddy covariance technique to (1) quantify and compare the carbon, water and energy budgets across diverse ecosystems; (2) quantify the environmental and biotic controlling mechanism on ecosystem carbon, water and energy fluxes; (3) validate the soil-vegetation-atmosphere model; and (4) serve the integrated study of terrestrial ecosystem carbon and water cycle. Over the last decades, great advancements have been made in the theory and technology of flux measurement, ecosystem flux patterns, simulation and scale conversion by Asian flux community. The establishment of ChinaFLUX has greatly filled the gap of flux observation and research in Eurasia. To further promote the flux measurement and research, accelerate data sharing and improve the data quality, it is necessary to present a methodological system of flux estimation and evaluation over complex terrain and to develop the integrated research that combines the flux measurement, stable isotope measurement, remote sensing observation and GIS technique. It also requires the establishment of the Joint Committee of Asian Flux Network in the Asia-Pacific region in order to promote the cooperation and communication of ideas and data by supporting project scientists, workshops and visiting scientists.
