Wildfires, bamboo and aerosols are becoming topics of research interest in the south-western Amazon because their impact on local ecosystems may influence the future climate on Earth. Their interaction is particularly important because it can self-amplify, potentially leading to unexpected consequences such as a decrease in carbon storage capacity due to the dominance of bamboo ecosystems after fire. This article synthesizes the discrete pieces of knowledge on each of these components to develop a conceptual model of wildfires–bamboo–aerosols relationships and to identify future research agendas. The interaction between wildfires and bamboo is controversial because the answer to whether bamboo significantly enhances the probability of wildfire events remains elusive. However, the ongoing deforestation of the Amazon is a possible trigger for increased interactions between wildfires and bamboo. A positive feedback likely exists in an area where aerosols produced by wildfires induce subsequent wildfires. Aerosols can form an oversupply of cloud condensation nuclei, which delays rainfall. Alternatively, they can absorb solar radiation and cool the Earth’s surface, which suppresses cloud formation. Little research has been conducted on the relationship between bamboo and aerosols in the Amazon. However, there is some indirect evidence that bamboo can be a significant producer of aerosols, which then affect wildfires by changing rainfall patterns. Our integrative approach will help to identify the triangular relationship between wildfires, bamboo and aerosols.

西南亚马逊地区野火,竹子和气溶胶之间的相互作用:一个概念模型

野火,竹子和气溶胶正成为西南亚马逊地区研究的热点,因为它们对当地生态系统的影响可能会影响地球上未来的气候。它们之间的相互作用特别重要,因为它可以自我放大,并有可能导致意想不到的后果,例如由于火灾后竹生态系统的优势而导致碳储存能力下降。本文综合了这些要素中每个要素的离散知识,以开发野火-竹-气溶胶关系的概念模型并确定未来的研究议程。野火与竹子之间的相互作用是有争议的,因为关于竹子是否显着提高野火事件发生概率的答案仍然难以捉摸。然而,亚马逊地区持续的森林砍伐可能触发野火与竹子之间的互动。在由野火产生的气溶胶引起随后的野火的地区可能存在积极的反馈。气溶胶会形成云凝结核的供过于求,从而延迟降雨。或者,它们可以吸收太阳辐射并冷却地球表面,从而抑制云的形成。关于亚马逊地区竹与气溶胶之间关系的研究很少。但是,有间接证据表明,竹子可以是重要的气溶胶生产商,然后通过改变降雨方式影响野火。我们的综合方法将有助于确定野火,竹子和气溶胶之间的三角关系。在由野火产生的气溶胶引起随后的野火的地区可能存在积极的反馈。气溶胶会形成云凝结核的供过于求,从而延迟降雨。或者,它们可以吸收太阳辐射并冷却地球表面,从而抑制云的形成。关于亚马逊地区竹与气溶胶之间关系的研究很少。但是,有间接证据表明,竹子可以是重要的气溶胶生产商,然后通过改变降雨方式影响野火。我们的综合方法将有助于确定野火,竹子和气溶胶之间的三角关系。在由野火产生的气溶胶引起随后的野火的地区可能存在积极的反馈。气溶胶会形成云凝结核的供过于求,从而延迟降雨。或者,它们可以吸收太阳辐射并冷却地球表面,从而抑制云的形成。关于亚马逊地区竹与气溶胶之间关系的研究很少。但是,有间接证据表明,竹子可以是重要的气溶胶生产商,然后通过改变降雨方式影响野火。我们的综合方法将有助于确定野火,竹子和气溶胶之间的三角关系。或者,它们可以吸收太阳辐射并冷却地球表面,从而抑制云的形成。关于亚马逊地区竹与气溶胶之间关系的研究很少。但是,有间接证据表明,竹子可以是重要的气溶胶生产商,然后通过改变降雨方式影响野火。我们的综合方法将有助于确定野火,竹子和气溶胶之间的三角关系。或者,它们可以吸收太阳辐射并冷却地球表面,从而抑制云的形成。关于亚马逊地区竹与气溶胶之间关系的研究很少。但是,有间接证据表明,竹子可以是重要的气溶胶生产商,然后通过改变降雨方式影响野火。我们的综合方法将有助于确定野火,竹子和气溶胶之间的三角关系。
