摘要
2010～2011年对桑沟湾楮岛海区大叶藻床的调查研究显示,其生物量年度变化为313.5～769.3gDW/m2,在夏季达到最高值;初级生产力年度内为2.0～6.4gDW/m2.d;总组织含碳量为35.5%;来自海草初级生产力的固碳贡献约为543.5gC/m2.yr。大叶藻附着植物生物量较小,年平均约为21.2g/m2,固碳贡献约30gC/m2.yr;作为菲律宾蛤仔增殖场,来自蛤仔的固碳贡献约63.15gC/m2.yr,此外,参照已有研究的数据,将来自草床捕获颗粒的碳贡献等计算在内,桑沟湾大叶藻床扩增固碳量为1180gC/m2.yr,总量达290MgC/yr。
Seagrass meadows occupy less than 0.2%of the area of the world ＇ s oceans but are estimated to contribute 10% of the yearly estimated organic carbon burial.Globally,seagrass ecosystems could store as much as 19.9Pg organic carbon.The high carbon storage capacity in seagrass meadows may result from the high primary production of seagrass meadows and their capacity to filter out particles from the water column and store them in soils.Eelgrass,Zostera marinais one of the common seagrass species in the northern hemisphere.Investigation in Sanggou Bay showed that the biomass of eelgrass varied between 313.5and 769.3g DW /m^2 from 2011to 2012,with the maximum of 738.1g DW /m^2 in summer.Primary production was about 2.0～6.4g DW /m^2.d and tissue carbon content was 35.5%in the plant.Stored carbon in the eelgrass meadow from primary production was about 543.5gC /m^2.yr.Biomass of algal epiphyte was small,with a wet weight of 21.2g/m^2 and contributed 30g C /m^2.yr carbon storage.As a Ruditapesp hilippinarumstock enhancement area,the carbon sink contribution from the clam was 63.15g C /m^2.yr.In addition,when other carbon source,such as stripped particles was considered,the carbon pool capacity was 1 180g C /m 2.yr and the whole of the bed can reach 290Mg C /yr.
