AsiaFlux (http://www.asiaflux.net/) was established in 1999 as the Asian arm of FLUXNET, the worldwide flux network, to develop collaborative research and data sets on the cycles of carbon and water in key ecosystems in Asia, to organize workshops and training on current and related global change themes, and to cultivate next generation scientists to be informed leaders with skills and perspectives. Over the past 20 years, AsiaFlux has developed into a regional research network composed of 28 member countries. More than 100 flux observation towers were built in Asia, covering diverse terrestrial ecosystems. Researchers of AsiaFlux have made great progress in flux observation, remote-sensing and ecosystem modeling, and made outstanding contribution to quantifying global carbon balance and understanding the functions of Asian terrestrial ecosystems. AsiaFlux will continue to lead flux-related research, contribute to the achievement of sustainable development in Asia, and provide an open forum for both field researchers (data providers) and remote-sensing / modeling researchers (data users) to encourage their communication and collaboration.
　AsiaFlux held a special workshop in 2019 in Takayama, Japan, to celebrate the 20^th anniversary with support from Gifu University and National Institute for Environmental Studies (NIES). In the workshop, a special session was organized to look back on the past and project the future of AsiaFlux. Seven speakers were invited and talked about principal research topics in AsiaFlux: 1) carbon dioxide (CO₂) flux observation, 2) water and energy fluxes, 3) soil respiration, 4) volatile organic compound exchange, 5) ecosystem processes, 6) remote sensing, and 7) terrestrial biosphere modeling. Based on these presentations, seven review papers were planned. This issue is composed of five review papers on water and energy fluxes (Kang and Cho, 2021), soil respiration (Sha et al., 2021), volatile organic compound (Tani and Mochizuki, 2021), ecosystem processes (Chang et al., 2021) and ecosystem modeling (Ito and Ichii, 2021). The other two review papers on eddy CO₂ flux and remote sensing will be presented soon in this journal, Journal of Agricultural Meteorology. We are grateful to all the authors of these impressive review papers and the editorial board of The Society of Agricultural Meteorology of Japan on behalf of AsiaFlux.

AsiaFlux的回顾与未来展望

AsiaFlux（http://www.asiaflux.net/）成立于1999年，是FLUXNET（全球通量网络）的亚洲分支，致力于开发有关亚洲主要生态系统中碳和水循环的合作研究和数据集，以期组织有关当前和相关的全球变化主题的研讨会和培训，并培养下一代科学家，使其成为具有技能和观点的知情领导人。在过去的20年中，AsiaFlux已发展成为一个由28个成员国组成的区域研究网络。亚洲建造了100多个通量观测塔，涵盖了各种陆地生态系统。AsiaFlux的研究人员在通量观测，遥感和生态系统建模方面取得了长足的进步，并为量化全球碳平衡和理解亚洲陆地生态系统的功能做出了杰出贡献。
　AsiaFlux 2019年在高山，日本召开了专题研讨会，为庆祝20^日从岐阜大学和国立环境研究所（NIES）支持周年。在研讨会上，组织了一次特别会议，回顾了过去并展望了AsiaFlux的未来。邀请了7位发言人并就AsiaFlux的主要研究主题进行了讨论：1）二氧化碳（CO ₂）通量观测，2）水和能量通量，3）土壤呼吸，4）挥发性有机化合物交换，5）生态系统过程，6）遥感；以及7）陆地生物圈建模。基于这些介绍，计划了七篇评论论文。本期由五篇有关水和能量通量（Kang和Cho，2021年），土壤呼吸作用（Sha等人）的综述论文组成。（2021年），挥发性有机化合物（Tani和Mochizuki，2021年），生态系统过程（Chang等人，2021年）和生态系统建模（Ito和Ichii，2021年）。有关涡旋CO ₂通量和遥感的其他两篇综述论文将很快在该期刊《农业气象》上发表。我们感谢这些令人印象深刻的评论文章的所有作者，以及代表亚洲通气协会的日本农业气象学会编辑委员会。
