摘要

Above ground biomass (AGB) is a tool for estimating carbon storage capacity of plants and hence the estimation methods are crucial. Karankadu mangrove swamp in the Palk Bay, Southeast coast of India is characterized by the presence of young mangrove species Avicennia marina (A. marina). AGB of A. marina in Karankadu mangrove swamp with 10 hectares (ha) plots was estimated using the non-destructive allometric method. Analyses of allometric regression comprised of leaves, branches and stems of A. Marina depend upon the independent variables of diameter at breast height (DBH), height (H) and basal area (BA). Average AGB of A. marina in the Karankadu mangrove swamp was found to be 10.71 t h(-1). A. Marina species amidst in hyper saline conditions effectively captures the atmospheric CO2 and storing them as biomass in the above ground parts than that of terrestrial ecosystem. Above ground carbon (AGC) content of A. marina trees calculated using AGB values was ranged between 1.15 and 7.92 t ha(-1).

Marina的叶子,分支和茎组成的异速回归分析取决于胸高(DBH),身高(H)和基底面积(BA)的直径的独立变量。在Karankadu红树林沼泽中,A。marina的平均AGB被发现为10.71 t h(-1)。 A.在高盐度条件下的滨海物种可以有效捕获大气中的CO2,并将其作为生物质存储在地面上比陆地生态系统高的位置。使用AGB值计算的滨海树的地上碳(AGC)含量在1.15至7.92 t ha(-1)之间。
