Abstract
Myanmar has the second largest area of mangrove forests in South East Asia while suffering high deforestation rates and forest degradation. However, monitoring results from existing studies in mangrove forests vary widely while specific estimates on carbon density for this forest type are deficient. Also, data from mangrove inventory plots used for the 2018 Myanmar forest reference level refer only to commercial timber and do not include other carbon pools. The results in this study based on four carbon pools allow for updating the emission factors in mangrove forests expressed in CO 2 from 125.43 ± 15.06 Mg ha –1 to 1 377.07 ± 67.04 Mg ha –1 for Ayeyarwady region (Pyapon, Pathein, Latputta districts) and 1 583.27± 75.18 Mg ha –1 for Tanintharyi region (Kawthaung, Dawei districts) and can be used in (sub)national or jurisdictional forest reference level for REDD+. In addition, the georeferenced biomass estimates are useful for the calibration of space-based models of biomass estimation.
缅甸拥有东南亚第二大红树林面积，但森林砍伐率高，森林退化严重。然而，现有红树林研究的监测结果差异很大，而对这种森林类型的碳密度的具体估计缺乏。此外，用于2018年缅甸森林参考水平的红树林清查样地的数据仅涉及商业木材，不包括其他碳库。基于4个碳库的研究结果允许将伊洛瓦底江地区(Pyapon、Pathein、Latputta地区)的红树林二氧化碳排放因子从125.43±15.06 Mg ha -1更新为1 377.07±67.04 Mg ha -1，丹宁达依地区(Kawthaung、Dawei地区)的排放因子从1 583.27±75.18 Mg ha -1更新为REDD+的(次)国家或辖区森林参考水平。此外，基于地理的生物量估算对基于空间的生物量估算模型的校准也很有用。
