The method of measuring carbon sinks based on the changes in oxygen concentration in forest canop

Measuring forest carbon sinks is becoming a popular topic as the need of many countries’ carbon neutrality plans. This study demonstrated a simple and accurate method of forest carbon sinks measurement. By observing the daily average oxygen concentration in the canopy, the results showed that it presented a parabolic distribution from spring to fall in a year. The forest finished the cycle from releasing oxygen and sequestrating carbon dioxide to using oxygen and releasing carbon dioxide in this period. The calculated carbon sequestration of the forest was 101.39 t/hm2 /y, and the carbon sink was 15.09 t/hm2 /y. By calculating the changes in oxygen concentration in a growth cycle, the carbon sink was 16.29% of the carbon sequestration. © (2023), (Bio Tech System). All Rights Reserved.
