大岗山毛竹扩张对常绿阔叶林生态系统碳储特征的影响
Effects of Phyllostachys edulis Expansion on Carbon Storage of Evergreen Broad-Leaved Forest in Dagangshan Mountain, Jiangxi
摘要
Abstract
By using the method of time-space mutual substitution,the effects of Phyllostachys edulis expansion on carbon storage of evergreen broad - leaved forest in Dagangshan mountain were studied. The results showed that when evergreen broad-leaved forest changed to Ph. Edulis forest,the carbon storage of ecosystem reduced from 267.94 t/hm2 to 226.75 t/hm2,dropping by 15. 37% , among which the carbon storage in vegetation had a 12.01% decline from 93.26 t/hm2 to 82.06 t/hm2, the carbon storage in the soil decreased from 173.93 t/hm2 to 143.84 t/hm2,dropping by 17.30%. Meanwhile, the pattern of carbon storage in the ecosystem changed simultaneously, the ratio of aboveground/belowground storage turned from 1:2.69 to 1:4.0. However, the carbon capture and storage of Ph. Edulis forest with a net accumulation of 4.76 t/( hm2· a),were larger than those of evergreen broad-leaved forest with 4. 15 t/(hm2 · a), increasing by 14.18%. The results indicated the complexities of carbon cycles in the succession of forests.关键词
