摘要
在测定植被的含碳率的基础上,研究了西双版纳森林植被碳储量特征.结果表明,植被平均含碳率为35.91%~50.12%,按照生物量加权的含碳率为47.33%~52.10%;乔木层平均碳储量范围为13.77~115.21t/hm2,乔木层分配比例最大的干部分碳储量比例均超过了50%;7种森林类型的乔木植被主要器官碳储量之间、林分因子之间以及主要器官碳储量与林分因子之间均存在一定的相关性(P【0.05);林下植被碳储量范围为3.22~19.45t/hm2;灌木、草本以及林下植被总碳储量与立地乔木植被的碳储量的回归关系均达到显著水平(P【0.05);林下植被碳储量与丰富度指数的回归关系达到显著水平(P【0.05),但与多样性指数和均匀度指数的回归关系均未达到显著水平(P【0.05).
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).
