Comparisons of climate condition, carbon fluxes and net biome productions among different farmlands.

<p>Climate condition includes annual mean air temperature (MAT, °C), annual precipitation (P, mm). Carbon fluxes include gross ecosystem production (GEP, gCm⁻²y⁻¹), ecosystem respiration (RE, gCm⁻²y⁻¹) and net ecosystem production (NEP, gCm⁻²y⁻¹).</p><p>Comparisons of climate condition, carbon fluxes and net biome productions among different farmlands.
