摘要

在美国西南部的森林中,气候变化和一个多世纪以来人为火灾造成的燃料负荷增加的综合影响正在导致更大、更严重的野火。在干燥针叶林中恢复频繁用火可以减轻严重火灾的风险,但在预计气候变化的情况下,这些处理方法对植被组成和结构的影响仍不确定。我们使用森林景观模型来评估疏伐和规定燃烧对海拔梯度干旱针叶林的影响,包括低海拔松柏林地、中海拔松柏林和高海拔针阔混交林。在低海拔地区,处理并不能防止森林覆盖率和生物量的损失,同时也会降低松柏和桧柏的丰度。在中海拔地区,火烧效应的变化有利于维持老树群落,从而保持了树种的多样性,特别是松柏,到本世纪末,松柏的地上生物量比未进行处理时增加了 5.41 兆克/公顷。对干燥针叶林的处理改变了处理区域以外的火灾效应,从而增加了老龄松树群(Picea englemannii)和杉木群(Abies lasiocarpa)的覆盖率和生物量:我们的研究结果表明,疏伐和规定焚烧可以保护古老的群落免受林分替代火灾的影响,从而提高干旱针叶林的树种多样性。此外,我们的研究结果表明,主要在高风险火灾频发的干燥松林中实施的处理方法可以降低中海拔地区高风险火灾向高海拔森林蔓延的几率,从而有利于亚高山物种保护。

期刊介绍: Journal of Applied Ecology publishes novel, high-impact papers on the interface between ecological science and the management of biological resources.The editors encourage contributions that use applied ecological problems to test and develop basic theory, although there must be clear potential for impact on the management of the environment.
