红树林是热带地区最重要的碳(C)汇，保护红树林是抵消碳排放和气候变化的重要手段。因此，建议将红树林作为减少毁林和退化所致排放量(REDD+)计划的一个重要组成部分，该计划要求严格量化生态系统碳储存，以便监测临时碳封存和排放。尽管如此，人们对越南红树林生态系统碳储存的了解相对较少，因为这些系统构成了越南海岸线的很大比例。在这项研究中，通过测量树木、根、木质碎屑的生物量以及沉积物有机碳和总深度来量化越南梅卡茂国家公园(CMNP)热带红树林的生态系统碳储量。结果表明，地上部分和地下部分碳蓄积量分别为90.2+/-15.8~115.2+/-19.3和629.0+/-32.5~687.0+/-29.2MGC ha(-1)。地上和地下碳储量的组合导致了高的生态系统碳储量，变化范围为719.2+/-38.0~802.1+/-12.3mgCha(-1)，并从边缘向林内略有增加。CMNP的13,400公顷红树林储存了10.3(+/-0.8)×10(6)mg的碳，相当于38.0(+/-3.0)×10(6)mg的CO(2)e。这一结果表明，保护红树林是增加生态系统碳储存和抵消区域尺度上碳排放的需要。()2014爱思唯尔B.V.版权所有。
Mangrove forests constitute the most important sink of carbon (C) in the tropics, the conservation of which is an essential mean in offsetting C emissions and climate change. Mangrove forests are therefore suggested to be an important component of reducing emissions from deforestation and degradation (REDD+) schemes, which require scrupulous quantification of ecosystem C storage in order to monitor temporal C sequestration and emissions. Despite this, proportionally less is known about ecosystem C storage of mangrove forests in Vietnam, where these systems constitute a large proportion of its coastline. In this study, ecosystem C storage of a tropical mangrove forest in Mui Ca Mau National Park, Vietnam (CMNP) was quantified by measuring biomass of trees, roots, and downed woody debris, and sediment organic C and overall depth. Results showed that above-and below-ground C stock ranged from 90.2 +/- 15.8 to 115.2 +/- 19.3 and from 629.0 +/- 32.5 to 687.0 +/- 29.2 MgC ha(-1), respectively. The combination of the above- and below-ground C stocks resulted in a high ecosystem C storage, which ranged from 719.2 +/- 38.0 to 802.1 +/- 12.3 MgC ha(-1), and slightly increased from fringe toward interior forest. The 13,400 ha of mangrove forests in the CMNP were estimated to store 10.3 (+/- 0.8) x 10(6) Mg of C, which is equivalent to 38.0 (+/- 3.0) x 10(6) Mg of CO(2)e. The present results suggest that the conservation of mangrove forest is needed to increase ecosystem C storage and to offset C emissions at the regional scale. () 2014 Elsevier B.V.
