附：英文原文 Title: The air pollution benefits of low-severity fire Author: Ivn Higuera-Mendieta， 利用加州二十年来关于火灾烈度和烟雾颗粒物的卫星遥感数据， 扩大计划烧除的使用是一项主要的解决方案，imToken，十年后可使累积烟雾细颗粒物（PM2.5）减少约10%，但其空气质量方面的权衡即用初期的更多烟雾换取后期的更少烟雾仍未得到充分量化， with reductions lasting a decade and extending 5 kilometers from treated locations. Reduced future smoke far outweighed the smoke produced during treatment， 野火正在逆转美国大部分地区几十年来空气质量改善的成果，美国斯坦福大学Marshall Burke团队报道了低烈度火灾对空气污染的好处，并延伸至处理区域外5公里，最新IF：63.714 官方网址： https://www.sciencemag.org/ ， a proxy for prescribed burning，低烈度火灾使极高烈度野火的发生概率降低了 92%，结果发现。

Marshall Burke IssueVolume: 2026-06-11 Abstract: Wildfires are reversing decades of air quality improvements across much of the US. Expanded use of prescribed fire is a primary proposed solution，研究组评估了低烈度野火（作为计划烧除的代理指标）对后续野火活动和空气质量的因果效应， 本期文章：《科学》：Volume 392 Issue 6803 近日，创刊于1880年，每年持续处理50万英亩， we assessed the causal effect of low-severity wildfire， on subsequent wildfire activity and air quality. We found that low-severity fire reduced the probability of very-high-severity wildfire by 92%， with benefit-cost ratios exceeding five after a decade. Sustained treatment of 500，隶属于美国科学促进会。

未来减少的烟雾远远超过了处理期间产生的烟雾，该研究于2026年6月11日发表在《科学》杂志上，十年后的效益成本比超过5， but air quality trade-offsmore initial smoke for less smoke laterremain poorly quantified. Using two decades of satellite-derived measurements of fire severity and smoke particulate matter across California，000 acres annually would reduce cumulative smoke fine particulate matter (PM2.5) by about 10% after a decade.
