摘要:采用时空替代法对江西大岗山毛竹(Phyllostachys edulis)扩张对常绿阔叶林生态系统碳储特征的影响进行了研究。结果表明:毛竹扩张导致常绿阔叶林逐渐演变成毛竹林,森林生态系统总的碳储量由267.94 t/hm2减少到226.75 t/hm2,减少了15.37%,其中植被碳储量由93.26 t/hm2减少到82.06 t/hm2,减少了12.01%;土壤碳储量由173.93 t/hm2减少到143.84 t/hm2,减少了17.30%;同时生态系统碳储格局发生明显变化,地上/地下碳储量比由1∶2.69变为1∶4.0。然而,森林生态系统的植被年固碳量却有所增加,由常绿阔叶林的4.15 t/(hm2.a)增加到毛竹林的4.76 t/(hm2.a),提高了14.18%,反映了森林演变过程中生态系统碳储特征的复杂性。
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.
