fluxes
    Average daily ecosystem respiration during the winter period (from November 1 to April 3) was 2.58 g·m-2·d-1 and the result shows that: ①C O2 concentration near the ground and CO2 fluxes were changing in the same pace, and the seasonal dynamics of CO2 fluxes appeared marked linear relationships with air temperature.
