Application of LICA Soil Greenhouse Gas Flux Monitoring System

1 Abstract

The process of soil Greenhouse gas emissions or absorptions is extremely complex in terrestrial ecosystems. It has become an urgent need for soil greenhouse gas researchers to achieve synchronization and in situ monitoring of multiple soil greenhouse gases. Based on this, Beijing LICA United Technology Limited (Hereinafter referred to as LICA) research and develop a series of soil gas flux monitoring products.

PS-9000 Portable Soil Carbon Flux Automatic Measurement System, SF-9000 Multi-channel Soil Carbon Flux Automatic Measuring System can work with 18 survey chambers, which is designed to measure soil CO2 flux at multiple points and realize continuous and long-term monitoring of soil carbon flux. SF-3500 Multi-channel Automatic Soil Gas Flux System (The old version is SF-3000), which is designed to measure the gas flux of CO2, CH4, N2O, NH3 and other gas flux by connecting a variety of gas analyzers, and to measure the isotope value of 13CO2, 12C18O16O, 15N14NO by connecting other isotope analyzers, can collect a continuous dataset from up to 18 chambers to characterize spatial and temporal variation of gas exchange over a research area.

LICA focuses on the research and development and production of domestic ecological instruments. It is believed that with increasing investment in research and development, and accumulation of market and time, LICA will produce more and better ecological instruments and provide more valuable products to more customers at home and abroad.

3 Application Articles

From research & development and production up to now, many scientists have used these products for many studies. For example, the wetland and climate change team from Institute of Wetland Research, Chinese Academy of Forestry took the Sichuan Zoige Plateau peatland as the research object, relied on PS-9000 Portable Soil Carbon Flux Automatic Measurement System and combined in-situ observations and laboratory experiments to study the response of Zoige Plateau peatland ecosystem carbon emissions (Ecosystem respiration and soil respiration) to extreme drought events in different periods of plant growing season, and reveal the driving mechanism of plant and soil enzyme activities on peatland carbon emission. One research team used PS-3000 Portable Automatic Soil Respiration System to measure the ecosystem respiration (Re) and CH4 fluxes on slopes with different aspects [north-facing (shady) and south-facing (sunny) slopes], and in different altitudinal positions (lower, middle, and upper slope positions) during two consecutive growing seasons (2017 and 2018). Aiming to elucidate the patterns of Re and CH4 fluxes and to quantify the relative contributions of abiotic and biotic factors in regulating Re and CH4 fluxes at the watershed scale of a Tibetan alpine grassland. Another research team from Institute of Geographic Sciences and Natural Resources Research, Chinese Academy of Sciences concurrently measured carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O) fluxes and their total balance in an alpine meadow of the Qinghai-Tibetan Plateau (QTP) in response to three levels of warming (ambient, +1.5°C, +3.0 °C) by SF-3500 Multi-channel Automatic Soil Gas Flux System to understand (a) what are the differences in the warming responses of CO2 versus CH4 and N2O fluxes, (b) what is the short-term sensitivity of annual GHG fluxes to different warming levels, and (c) what are the differences in the warming responses of GHG fluxes between the growing season and non-growing season. LICA is committed to supporting researchers in their research career, and LICA will take a new look to meet more challenges and opportunities and serve new and old customers with greater enthusiasm.
