摘要

监测森林碳储量和固碳潜力对于评估林业在二氧化碳(CO 2)去除中的作用至关重要。作为城市绿化战略的一部分,在印度城市建立的城市保护区森林(URFs)对二氧化碳抵消做出了重大贡献。然而,他们关于二氧化碳去除以减缓气候变化的信息有限。为了弥补这一知识差距,采用了破坏性和非破坏性技术的库存调查来估计这一点。据估计,Bhomoraguri URF的总碳储量为218.75 Mg ha⁻¹ ,Balipara URF的总碳储量为236.15 Mg ha⁻¹ ,分别相当于799.1 Mg CO₂ha⁻¹ 和866.65 Mg CO₂ha⁻¹ 。碳储量在不同的碳库中各不相同,SOC的贡献最大(Bhomoraguri的113.6 Mg ha⁻1和Balipara的124.85 Mg ha⁻1),其次是上层(97.33和103)。25 Mg ha - 1),最低的是草药层(分别在Bhomoraguri和Balipara为2.68和3.05 Mg ha - 1)。对林下碳储量贡献最大的是大地构造、黄檀和无花果。在林下层,爬行类、长爪蟹和梭鲈等物种对固碳有显著贡献。大量的碳储量和固存潜力表明,urf具有作为碳汇的潜力,有助于抵消大气中增加的CO 2水平。研究结果为减缓气候变化提供了宝贵的见解,并强调了基于自然的解决方案在应对未来各种气候情景下的全球气候挑战方面的潜力。

Carbon stocks and sequestration potential in urban reserve forests: Insights for climate change mitigation
Monitoring forest carbon stock and sequestration potential is vital for evaluating the role of forestry in Carbon dioxide (CO₂) removal. Urban reserve forests (URFs) established in Indian cities as part of urban greening strategy, contribute significantly to CO₂ offset. However, their information on CO₂ removal for climate change mitigation is limited. To bridge this knowledge gap, an inventory survey employing both destructive and non-destructive techniques were used to estimate this. The estimated total carbon stock was 218.75 Mg ha⁻¹ for Bhomoraguri URF and 236.15 Mg ha⁻¹ for Balipara URF, which is equivalent to 799.1 Mg CO₂ ha⁻¹ and 866.65 Mg CO₂ ha⁻¹ of CO₂ being sequenced for, respectively. The noted carbon stock varied across carbon pools, with the highest contributions from SOC (113.6 Mg ha⁻¹ in Bhomoraguri and 124.85 Mg ha⁻¹ in Balipara), followed by overstory layer (97.33 and 103. 25 Mg ha⁻¹) and the lowest from herbs layers (2.68 and 3.05 Mg ha⁻¹ in Bhomoraguri and Balipara, respectively). The top contributors to carbon stock in the overstory are Tectona grandis, Dalbergia sissoo, and Ficus hirta. In the understory layer, species such as Bidens reptans, Cynodon dactylon, and Piper betle, showed notable contributions to carbon sequestration. The substantial carbon stock and sequestration potential suggests that URFs have the potential to serve as carbon sinks, helping to offset increased atmospheric CO₂ levels. The results offer valuable insights for climate mitigation and underscore the potential of nature-based solutions in addressing global climate challenges under various future climate scenarios.
