摘要

林下燃料对火灾行为和树冠火灾的发生有着深远的影响。准确预测林下燃料的火灾行为是估算野火和规定火灾事件中火灾强度和严重程度的重要组成部分。本研究主要研究了东德克萨斯松木和硬木生态系统中入侵黄松(Ilex vomitoria)、女儿树(Ligustrum sinense)和中国油脂(Triadica sebifera)扩张相关的燃料负荷参数的时间和季节变化。入侵物种出没地点的燃料负荷数据表明，与1988年的估计相比，林下生物量显著增加，这表明明显需要修订区域燃料模型。建立了三种入侵物种的多元和简单回归生物量预测方程，以方便燃料负荷估算。这些改进的预测方程将加强德克萨斯州东部的火灾管理工作以及入侵物种缓解工作。

Biomass estimations of invasives Yaupon, Chinese Privet and Chinese Tallow in east Texas Hardwood and Pine Ecosystems

Forest understory fuels can have profound effects on fire behavior and crown fire initiation. Accurate fire behavior prediction in understory fuels is an essential component for estimating fire intensity and severity during wildfire and prescribed fire events. This study focused on estimating temporal and seasonal changes in fuel loading parameters associated with the expansion of invasive yaupon (Ilex vomitoria), Chinese privet (Ligustrum sinense), and Chinese tallow (Triadica sebifera) in East Texas pine and hardwood ecosystems. Fuel loading data of invasive species infested sites indicated significant increases in understory biomass when compared to 1988 estimates, suggesting a clear need to revise regional fuel models. Multiple and simple regression biomass prediction equations were developed for all three-invasive species to facilitate fuel load estimates. These improved prediction equations will enhance fire management efforts as well as invasive species mitigation efforts in east Texas.
