中文摘要 | 森林之天然更新,在以前遊牧開墾地區是很重要的。雖然有報導次生林具有吸收和儲存大量碳之潛能,但欠缺那些在演替階段初期先驅樹種之生物量累積之資料。此等資料有助於評估次生林在碳吸存方面之貢獻。本研究之目的為,對Dillenia suffruticosa林分進行生物量推估和發展生物量推估模式。在D. suffruticosa林分內設置6個每個面積為10 x 10 m之樣區。於樣區內進行整株林木和各別部分(樹幹。枝條和葉)生物量推算。研究結果顯示林木各部位生物量和與胸高直徑關係之對數回歸式,具有63~89%之變異之解釋力(p ≤ 0.01)。D. suffruticosa林分每公頃地上總生物量為5.2噸。樣區間地上總生物量之高度差異顯示林分內各樣區正處在不同之演化階段,但低生物量反映出此林分處於嚴重劣化,或許需要更久之時間來回復。然而D. suffruticosa林分之天然更新的確對遊牧開墾地區生物量和碳之累積有所貢獻。 |
英文摘要 | The natural regeneration of forests is an important part of the recovery of former shifting-cultivation areas. Regenerating secondary forests are reported to have the potential to assimilate and store large quantities of carbon. However, there is a lack of information on biomass accumulation by pioneer species that dominate early successional processes, especially in tropical Asia. This information would help quantify their role in carbon storage and sequestration. The objectives of this study were to estimate the biomass accumulation and develop a biomass estimation model for a Dillenia suffruticosa stand. Six 10 x 10-m plots were established in a D. suffruticosa stand. A destructive harvesting method was used to estimate the total and tree component (stem, branches, and leaves) biomass values. An analysis showed that the biomass relationship for each tree component using diameter at breast height (dbh) as an independent variable in a log relationship accounted for 63~89% of the variations at p ≤ 0.01. The estimated total aboveground biomass of the D. suffruticosa stand was 5.2 t ha^(-1). The high variability of the estimated total biomass in each study plot indicated that the stand was at different stages of succession, but the low biomass accumulation is a reflection of severely degraded conditions and may require a longer period for recovery. However, the natural regeneration of D. suffruticosa has contributed to biomass and carbon accumulation in a former shifting-cultivation area. |
