世界上大约一半的热带泥炭地位于东南亚 (SE) 亚洲，它们是主要的碳 (C) 汇。该地区近 80% 的天然泥炭地已被砍伐和排干，其中大部分为种植园和农业用地。这种转化增加了泥炭的氧化，导致碳以温室气体排放的形式快速流失到大气中，并增加了泥炭对火灾的脆弱性，从而产生区域烟霾，对人类健康产生严重影响。恢复这些系统以缓解环境问题的尝试收效有限。我们回顾了目前对东南亚完整和退化泥炭地的了解，以帮助制定恢复这些生态系统的前进方向。因此，我们从生物多样性、碳储存、水文和养分方面严格审查它们，同时关注地上和地下子系统。然后，我们提出了一种更好地管理和恢复退化泥炭地的方法，其中包括明确考虑多种相互作用的生态因素以及依赖转化泥炭地为生的当地社区的参与。我们认为，作为导致泥炭地开发的过程涉及地上和地下子系统的修改，这是一种明确承认这两个子系统的综合方法它们的相互作用是热带泥炭地成功管理和恢复的关键。综合与应用。不仅要更好地了解碳储存及其在泥炭退化过程中的变化，还要深入了解生物群、营养动态、水文学以及生物和非生物反馈，这是为东南亚泥炭地管理和恢复制定更好解决方案的关键。通过应用基于科学和自然的解决方案，认识到地上和地下子系统之间的相互作用，并考虑到当地人民的生计需求，我们提出了一种方法来减轻这些标志性和独特的生态系统中正在发生的持续环境破坏。
About half of the world's tropical peatlands occur in Southeast (SE) Asia, where they serve as a major carbon (C) sink. Nearly 80% of natural peatlands in this region have been deforested and drained, with the majority under plantations and agriculture. This conversion increases peat oxidation which contributes to rapid C loss to the atmosphere as greenhouse gas emissions and increases their vulnerability to fires which generate regional smoke haze that has severe impacts on human health. Attempts at restoring these systems to mitigate environmental problems have had limited success.We review the current understanding of intact and degraded peatlands in SE Asia to help develop a way forward in restoring these ecosystems. As such, we critically examine them in terms of their biodiversity, C storage, hydrology and nutrients, paying attention to both above‐ground and below‐ground subsystems.We then propose an approach for better management and restoration of degraded peatlands that involves explicit consideration of multiple interacting ecological factors and the involvement of local communities who rely on converted peatlands for their livelihood.We make the case that as processes leading to peatland development involve modification of both above‐ground and below‐ground subsystems, an integrated approach that explicitly recognizes both subsystems and their interactions is key to successful tropical peatland management and restoration.Synthesis and applications. Gaining a better understanding of not just carbon stores and their changes during peat degradation, but also an in‐depth understanding of the biota, nutrient dynamics, hydrology and biotic and abiotic feedbacks, is key to developing better solutions for the management and restoration of peatlands in Southeast Asia. Through the application of science‐ and nature‐based solutions that recognize the interactions among the above‐ground and below‐ground subsystems, and taking into account the livelihood needs of local people, we propose a way to mitigate the ongoing environmental damage that is occurring in these iconic and unique ecosystems.
