Prof. LIANG Naishen from the National Institute of Environmental Studies, Associate Professor Jesper Riis Christiansen from the University of Copenhagen, Professor YI Zhigang from Fujian Agriculture & Forestry University, and Professor JI Yujie from Shenyang University of Science and Technology visited the Institute of Applied Ecology (IAE) for academic exchanges from July 30th to August 1st, 2019.

On July 30th, FANG Yunting, deputy director of IAE, presided over an academic exchange meeting. In the talk entitled ‘Long-term response and feedback of Asian terrestrial ecosystems carbon cycle to global warming’, Professor LIANG introduced their self-developed multi-channel automatic Open/Close-Path Air Chamber System (Liangber) which has been extensively used for carbon emission monitoring in east Asian forests, and talked about topics including the long-term soil warming experiment network, the effects of artificial warming and natural warming on forest soil carbon emission, and the use of radioactive ¹⁴C to evaluate the decomposition characteristics of soil carbon pool components under global warming. In the talk entitled ‘the role of hydrology for soil greenhouse gas dynamics-physical and microbiological perspectives from around the world’, Professor Christiansen presented response patterns of soil methane fluxes to moisture content changes, and a new hydrological gradient plot system for monitoring soil greenhouse gas emission. Subsequently, Dr. LIU Dongwei introduced the simulated warming experiment conducted at the Qingyuan Forest Ecosystem Research Station and summarized the project progress during the past three years. Youth researchers and graduate students who attended the academic exchange meeting expressed that they learned a lot from the talks.

From July 31 to August 1, Prof. LIANG and others visited the Qingyuan Forest Ecosystem Research Station and took a trip to the field experiments such as warming platform, the hydrological gradient platform and the tower network platform. The visitors affirmed and praised the experimental facilities and researches such as soil-atmosphere flux monitoring, put forward constructive opinions on the layouts of the experiments, and discussed the collaborative researches in the near future.
