Sundarban is the world's largest mangrove wetland. This study, conducted in 2016, to compare blue carbon sequestration with different natural metapopulations and a four-year-old (30% area)- (70% area)-mixed mangrove plantation under anthropoganic stress. The aims of the study is to find out the variations in soil ecological function indicators (pH, electrical conductivity, bulk density, soil texture, available nitrogn, phosphorus and soil organic carbon) and key ecological service indicator (soil blue carbon pool) between sites. Simpson's Index of dominance, diversity and Shannon-Weiner Index revealed that all the sites are under ecological stress, with the -dominated mudflat having the least biodiversity. It is also revealed that pH and electrical conductivity were highest in and -dominated metapopulations, whereas organic carbon was the highest under the mangrove plantation and -dominated site. Available nitrogen was recorded highest in the community with the sp.- association. The mixed mangrove plantation had the highest blue carbon pool. The species diversity was not found to be related with the distance from the nearby conserved mangrove forest, contrary to the island biogeography theory. This study concludes with a recommendation of mixed mangrove plantations to restore the degraded saline mudflats along the human settlements across the globe.
孙德尔本斯是世界上最大的红树林湿地。这项研究于2016年进行，旨在比较不同自然复合种群以及在人为压力下一片种植四年的（30%面积）-（70%面积）混合红树林种植园的蓝碳固存情况。该研究的目的是找出各地点之间土壤生态功能指标（pH值、电导率、容重、土壤质地、有效氮、磷和土壤有机碳）和关键生态系统服务指标（土壤蓝碳库）的差异。辛普森优势度指数、多样性指数和香农-韦纳指数表明，所有地点都处于生态压力之下，以[具体某种情况]为主的泥滩生物多样性最低。研究还表明，pH值和电导率在以[具体情况]为主的复合种群中最高，而有机碳在红树林种植园和以[具体情况]为主的地点最高。在与[某种物种]相关联的群落中，有效氮含量最高。混合红树林种植园的蓝碳库最大。与岛屿生物地理学理论相反，未发现物种多样性与距附近受保护红树林森林的距离有关。本研究最后建议通过混合红树林种植园来恢复全球人类住区沿线退化的盐碱泥滩。
