The characteristic of “stereoscopic” climates is fairly clear in Gongga Mountain,and various types of vegetation altitudinal belts ranging from subtropical vegetation to frigid zones vegetation were shaped along altitude.In this research,typical sample plot investigation method and allometric models were used to study the aboveground biomass and carbon storage of four typical vegetation altitudinal belts including evergreen and deciduous broad-leaved forest belt,mixed coniferous broad leaved forest belt,dark coniferous forest belt and alpine scrub belt in eastern slope of Gongga Mountain.The results show that:(1)The aboveground biomass of natural vegetation increased from lower to higher altitudinal zones until the maximum was reached and then declined as the altitude continued to increase.The aboveground biomass of the four vegetation altitudinal belts from low altitude to high was 233.49 t/hm²,524.55 t/hm²,415.81 t/hm²,20.86 t/hm²,respectively,indicating a maximum biomass of the mixed coniferous and broad leaved forest.The average individual plant aboveground biomass of the four vegetation altitude belts from low to high altitude was 320.11 kg,1 140.78 kg,623.15 kg,11.89 kg,respectively,which showed the same trend with the aboveground biomass of the vegetation altitude belts.(2)All the altitude belts analyzed as a whole,of the plant organs,leaf have the highest carbon content rate (48.52%),followed by branch (46.29%) and trunk (44.65%).The carbon storage of the four vegetation altitudinal belts from low to high altitude was 103.60 t/hm²,245.26 t/hm²,192.99 t/hm²,9.82 t/hm²,respectively.The correlation between aboveground biomass and mean annual precipitation reached a highly significant level,and mean annual precipitation was an important climate factor that affects the aboveground biomass distribution pattern in Gongga Mountain.
