Abstract

The Amazon fires have had a profound impact on the region's environment and the Earth's overall ecosystem. However, the full extent of the impact of these fires on their surroundings is not yet fully understood. This study utilizes annual composite and seasonal composite fire data from January 2001 to December 2022, along with CH₄, HCHO, CO, NO₂, SO₂, O₃, surface temperature, and precipitation data, to investigate the effects of Amazon fires on meteorological conditions and air pollutants during the 2001–2022 period. The study results show that: (1) over the past 22 years, the Amazon has experienced varying degrees of fires, with a decreasing trend in fire area. The largest fire area occurred in 2005, covering about 632,356 km². (2) Fires, pollutants, and precipitation are all seasonal in the Amazon region, as the area of fires is significantly higher in autumn and summer compared to winter and spring. (3) High surface temperatures are concentrated in the northern, eastern, and southern regions. (4) From 2001 to 2022, the fire area in the Amazon was negatively correlated with precipitation and positively correlated with surface temperature. (5) During the period of 2019–2022, fire areas were significantly and positively correlated with HCHO, NO₂, CH₄, and CO. There were also correlations between fire area and SO₂ and O₃. This study has, to a certain extent, explored the impact of fires on the Amazon environment, holding significant implications for the region's sustainable development.

2001 - 2022年亚马逊地区火灾时空分布及其大气变化分析

亚马逊大火对该地区的环境和地球的整体生态系统产生了深远的影响。然而，这些火灾对周围环境的影响程度尚不完全清楚。本研究利用2001年1月至2022年12月的年度复合和季节性复合火灾数据，以及CH4、HCHO、CO、NO2、SO2、O3、地表温度和降水数据，研究了2001 - 2022年期间亚马逊河流域火灾对气象条件和空气污染物的影响。研究结果表明：(1)近22年来，亚马逊地区经历了不同程度的火灾，火灾面积呈减少趋势；最大的火灾发生在2005年，面积约为632,356平方公里。(2)亚马逊地区火灾、污染物和降水均具有季节性，秋季和夏季火灾面积明显高于冬季和春季。(3)地表高温主要集中在北部、东部和南部。(4) 2001 ~ 2022年亚马孙雨林火灾面积与降水量呈负相关，与地表温度呈正相关。(5) 2019-2022年期间，火灾面积与HCHO、NO2、CH4、CO呈显著正相关，与SO2、O3呈显著正相关。本研究在一定程度上探讨了火灾对亚马逊环境的影响，对该地区的可持续发展具有重要意义。

期刊介绍： Water, Air, & Soil Pollution is an international, interdisciplinary journal on all aspects of pollution and solutions to pollution in the biosphere. This includes chemical, physical and biological processes affecting flora, fauna, water, air and soil in relation to environmental pollution. Because of its scope, the subject areas are diverse and include all aspects of pollution sources, transport, deposition, accumulation, acid precipitation, atmospheric pollution, metals, aquatic pollution including marine pollution and ground water, waste water, pesticides, soil pollution, sewage, sediment pollution, forestry pollution, effects of pollutants on humans, vegetation, fish, aquatic species, micro-organisms, and animals, environmental and molecular toxicology applied to pollution research, biosensors, global and climate change, ecological implications of pollution and pollution models. Water, Air, & Soil Pollution also publishes manuscripts on novel methods used in the study of environmental pollutants, environmental toxicology, environmental biology, novel environmental engineering related to pollution, biodiversity as influenced by pollution, novel environmental biotechnology as applied to pollution (e.g. bioremediation), environmental modelling and biorestoration of polluted environments. Articles should not be submitted that are of local interest only and do not advance international knowledge in environmental pollution and solutions to pollution. Articles that simply replicate known knowledge or techniques while researching a local pollution problem will normally be rejected without review. Submitted articles must have up-to-date references, employ the correct experimental replication and statistical analysis, where needed and contain a significant contribution to new knowledge. The publishing and editorial team sincerely appreciate your cooperation. Water, Air, & Soil Pollution publishes research papers; review articles; mini-reviews; and book reviews.
