The arbor biomass change with terrain factor in Xiaoqinling National Nature Reserve
According to the investigation of 56 quadrats in Henan Xiaoqinling,this study explored the change pattern of above-ground biomass of the Xiaoqinling forest trees and studied the change pattern of Pinus armandii biomass through allometric equations.The results showed:(1) the ground biomass was statistically correlative with the altitude factor;(2)with altitude rising the tree aboveground biomass showed a downward trend after rising;(3) armandi pine is the largest species abundance whose aboveground biomass showed a trend of gradual decline with altitude ascent,which is different from the change pattern of tree biomass on the ground,and this may be caused by the disadvantage in high elevation for armandi pine;(4) with altitude rising the biomass of each organ of armandi pine falls,which is in line with armandi pine biomass changes;(5) armandi pine aboveground biomass and underground biomass change trend is consistent,and their ratio presents a rising trend between 3.1 and 3.2 along with the elevation.
