Present study focuses on the carbon sequestration potential of five dominant mangrove species (Avicenia marina, Avicenia officinalis, Excoecaria agallocha, Rhizophora mucronata and Xylocarpous granatum) in Bhitarkanika and Mahanadi mangrove ecosystem. Water and soil parameters were sampled and analyzed for 10 selected stations along with aboveground biomass (AGB) and aboveground C (AGC) values. AGB value in the study area ranged from 15.00 ± 2.12 to 70.09 ± 6.68 tha⁻¹ for A. marina, 26.13 ± 3.19 tha⁻¹ to 616.94 ± 50.15 tha⁻¹ for A. officinalis, 3.56 ± 0.96 tha⁻¹ to 98.66 ± 5.24 tha⁻¹ for E. agallocha, 7.06 ± 2.21 tha⁻¹ to 224.41 ± 21.20 tha⁻¹ for R. mucronata, and 0.64 ± 0.21 tha⁻¹ to 6.25 ± 1.52 tha⁻¹ for X. granatum, respectively. AGC value ranged from 7.63 ± 1.08 to 35.65 ± 2.63 tha⁻¹ for A. marina, 1.73 ± 0.01 tha⁻¹ to 280.83 ± 21.29 tha⁻¹ for A. officinalis, 1.64 ± 0.41 tha⁻¹ to 44.95 ± 2.53 tha⁻¹ for E. agallocha, 3.44 ± 1.45 tha⁻¹ to 114.05 ± 10.29 tha⁻¹ for R. mucronata and 0.31 ± 0.10 tha⁻¹ to 3.25 ± 0.31 tha⁻¹ for X. granatum, respectively. The average SOC values in tha⁻¹ varied from 3.52 ± 0.12 to 7.71 ± 0.45. The total carbon (AGC + SOC) calculated for the study area varied from 55.20 ± 7.90 to 330.41 ± 111.97 tha⁻¹ with a mean total carbon of 124.11 ± 30.14 which is equivalent to 455.47 ± 110.56 tons of CO₂. Considering the total area of Bhitarkanika and Mahanadi mangrove ecosystem (672 + 141,589) to be 142,261 km², the mean CO₂e be 455.47 ± 110.56 tones, it is approx. 64,795,617.67 ≅ 64.80 TgC that were absorbed from the atmosphere, thus reducing the amount of carbon dioxide from the atmosphere.

印度东部红树林的高蓝碳储量

目前的研究重点是在Bhitarkanika和Mahanadi红树林生态系统中，五个主要的红树林物种（Avicenia marina，Avicenia officinalis，Excoecaria agallocha，Rhizophora mucronata和Xylocarpous granatum）的固碳潜力。对10个选定站点的水和土壤参数以及地上生物量（AGB）和地上C（AGC）值进行采样和分析。在研究区域AGB值从15.00±2.12范围至70.09±6.68 THA ^-1为A.码头，26.13±3.19 THA ^-1至616.94±50.15 THA ^-1为A.巴戟，3.56±0.96 THA ^-1到98.66±5.24 THA ^-1为E.海漆，7.06±2.21 THA ^-1至224.41±21.20 THA ^-1为R. mucronata，和0.64±0.21 THA ^-1至6.25±1.52 THA ^-1为X.石榴皮，分别。AGC值从7.63±1.08到不等35.65±2.63 THA ^-1为A.码头，1.73±0.01 THA ^-1至280.83±21.29 THA ^-1为A.巴戟，1.64±0.41 THA ^-1至44.95±2.53 THA ^-1对于E. agallocha， 3.44±1.45 tha ^-1至114.05±10.29 tha^-1用于R. mucronata和0.31±0.10 THA ^-1至3.25±0.31 THA ^-1为X.石榴皮分别。tha ^-1中的平均SOC值从3.52±0.12到7.71±0.45。为研究区域计算的总碳（AGC + SOC）在55.20±7.90到330.41±111.97 tha ^-1之间，平均总碳124.11±30.14，相当于455.47±110.56吨CO ₂。考虑到Bhitarkanika和Mahanadi红树林生态系统的总面积（672 + 141,589）为142,261 km ²，即平均CO ₂e为455.47±110.56音，约为 64,795,617.67≅64.80 TgC从大气中吸收，因此减少了来自大气的二氧化碳量。
