Distribution characteristics of forest biomass along the Chinese temperature gradient

  • Long-term forest biomass and meteorological data were used to study temperature gradient and
    forest biomass distribution characteristics, with weighted biomass and geographical meteorological correlation
    methods Total biomass and underground biomass along the temperature gradient showed similar distribution
    characteristics Biomass increased with increasing temperature until a certain temperature value, after which the
    forest biomass continued to increase with increasing temperature before biomass declined; this was followed by
     another sequence of increase-then-decrease above ground biomass showed little changes along the temperature
    gradient; direct decline was observed with increasing temperature. This was followed by a sequence of increase then-decrease with further increasing temperatures The response mechanisms of above ground and below ground
    plant growth to temperature gradient were found to be different, significant hysteresis was observed. For total
    forest biomass, above ground biomass contributed more than underground biomass, stem biomass contributed
    more than shoot biomass. These works indicate that there are clear rules correlating temperature change with
    forest biomass variations in China. The effect of temperature changes on forest productivity is very significant.
