中文摘要 | 土壤碳埋藏是使紅樹林發揮碳匯功能的主要過程。然而,紅樹林土壤碳庫中來自異源性或自源性輸入的沉積物質數量仍不確定。紅樹林衍生的碳埋藏通常透過監測其生產力和分解率來費力地估算。本研究為2種根系結構不同的紅樹林物種(水筆仔和海茄苳)構建了10個涵蓋不同棲地特徵的碳收支模式。結果顯示水筆仔碳埋藏率為0.25–1.55 Mg C ha-1 yr-1,海茄苳碳埋藏率為0.36–1.00 Mg C ha-1 yr-1。 結合其他研究,2種紅樹林的碳埋藏率與凋落物產量呈正線性相關,顯示水筆仔和海茄苳的碳埋藏率分別占凋落物產量的14.8%和10.9%。基於DistLM模型的dbRDA結果進一步顯示,風速和降雨是影響水筆仔和海茄苳碳埋藏的主要因素。 |
英文摘要 | Soil carbon burial is the major process enabling mangroves to function as carbon sinks. However, the amount of deposited materials derived from allochthonous or autochthonous inputs in the soil carbon pool of mangroves remains uncertain. Mangrove-derived carbon burial is often laboriously estimated by monitoring the production and decomposition. In this study, ten carbon budgets covering different habitat features were constructed in situ for two mangrove species (Kandelia obovata and Avicennia marina) with distinct root structures. The mangrove-derived carbon burial rate was 0.25–1.55 Mg C ha-1 yr-1 for K. obovata and 0.36–1.00 Mg C ha-1 yr-1 for A. marina. Combined with other studies, there were positive and linear correlations between the carbon burial rate and litterfall production for the two mangroves, which suggests that the carbon burial rate for K. obovata and A. marina can be estimated using 14.8 % and 10.9 % of the litterfall production rate, respectively. The results of dbRDA with DistLM models further showed that wind speed and precipitation were the main factors affecting carbon burial in K. obovata and A. marina mangroves. |
