- Abstract:
-
The dynamics of vegetational biomass and the carbon and nitrogen storage along the successional chronosequence in the foreland of Hailuogou Glaicier were investigated. The results showed that the total plant biomass presented the volatile increase with the successional process, increased from 0.95 t/hm2 to 163.79 t/hm2; as the most important components of the ecosystem, trees contributed more than 94.5% of the living plant biomass; vegetation carbon and nitrogen storage increased from 0.40 t/hm2 and 0.01 t/hm2 in the early succession stage, to 88.45 t/hm2 and 1.76 t/hm2 in the late succession stage, espectively; the storgae of carbon and nitrogen in trees was 35.27~99.85 t/hm2 and 1.11~1.99 t/hm2, respectively, accounting for 92.8% and 93.4% of the total vegetaion carbon and nitrogen pools, respectively. The carbon reserves of shrub and herbaceous layer contributed less to the total carbon and nitrogen reserves of vegetation.
