| 摘 要： | 为评价风景区在减缓全球气候变化方面的作用,研究了蜀南竹海风景区毛竹林生态系统的碳储量以及空间分配特征。结果表明:毛竹各器官碳含量介于0.451 2~0.531 3 g/g之间,碳含量从高到低排序为秆(0.531 3 g/g)>枝(0.517 3 g/g)>鞭(0.503 1 g/g)>叶(0.489 2 g/g)>蔸(0.459 0 g/g)>根(0.451 2 g/g);不同龄级的毛竹平均碳含量从高到低排序为Ⅳ(0.521 5 g/g)>Ⅲ(0.514 0 g/g)>Ⅰ(0.508 9 g/g)>Ⅱ(0.487 5 g/g)。毛竹林生态系统碳储量为105.07 t/hm2。其中,乔木层碳储量为40.88 t/hm2,土壤层碳储量为61.0 t/hm2,枯落物层碳储量最低,为3.19 t/hm2,分别占生态系统碳储量的38.91%、58.06%和3.91%,其分配上表现为土壤层碳储量最大。研究结果表明风景区在减缓大气CO2浓度方面有着重要的作用。

| Abstract: | In order to evaluate the role of scenic-spot bamboo ecosystem in carbon sequestration,the study had been made on the carbon storage and allocation of Phyllostachys edulis ecosystem in the scenic spot within the Southern Sichuan Bamboo Sea.The results indicated that the carbon content of every parts in P.edulis was between 0.451 2~0.531 3 g/g,the sequence of which was stem(0.531 3 g/g) > brance(0.517 3 g/g) > below-ground stem(0.503 1 g/g) > leaf(0.489 2 g/g) > stump(0.459 0 g/g) > root(0.451 2 g/g).The mean... |
