Due to lack of measurement, all previous studies are uniform vegetation average emission rate of 1.5 μg C gdw-1 h-1, the other VOCs estimate emissions as a whole.
Due to lack of measurements, all vegetation in previous studies used a uniform average emission rate of 1.5 ?g C gdw-1 h-1 to estimate emissions from other VOCs as a whole.
Due to the lack of measurement, the uniform average emission rate of 1.5 μ g cgdw − 1 h − 1 was used for all vegetation in previous studies, and other VOCs were used as a whole to estimate emissions.
