Abstract:Based on the vegetation carbon content rate that determined, we studied the carbon storage dynamics of forest vegetation in Xishuangbanna. The results showed that, the average vegetation content rate was ranging form 35.91% to 50.12%, and the average carbon content rate weighted by biomass was ranging form 47.33% to 52.10%. The average carbon storage of tree layer is in the range of 13.77~115.21t/hm2, cadre arbor layer distribution ratio of maximum carbon stocks the proportion to surpass 50%; there is a certain correlation between, the 7 types of forest vegetation carbon storage of main organs of trees stand factor and main organs of carbon storage and stand factor (P<0.05); understory vegetation carbon storage is in the range of 3.22~19.45t/hm2, herbs and shrubs; regression relationship between forest reserves total vegetation carbon and site arbor vegetation carbon storage was significant (P<0.05); regression relationship between forest vegetation carbon storage and richness index reached a significant level (P<0.05), but the regression relationship and diversity index and evenness index were not significant (P<0.05).
