摘要:

松材线虫病(PWD)因其发病迅速、致死率高,已成为严重威胁我国森林生态安全的重大病害之一。及时、精准的疫木监测是遏制疫情扩散的关键。针对松材线虫病疫木在早期、中期、晚期及末期不同发病阶段的生理与形态特征,系统梳理了卫星遥感、无人机遥感及多源遥感数据融合技术的松材线虫病监测原理与研究进展。卫星遥感在大范围中期、晚期及末期疫木调查中具有优势,但受限于时空与光谱分辨率,难以有效识别早期微弱信号;无人机可见光与多光谱遥感在中期、晚期监测中兼具高分辨率与低成本优势,但在早期生理胁迫阶段易出现漏检;无人机高光谱技术凭借连续窄波段优势,是捕捉早期细微光谱变化的最有效手段,但面临成本高与数据处理复杂的挑战。多源遥感数据融合技术通过整合多维度时空信息,能够弥补单一数据源的局限,是实现疫木全周期精细化监测的重要发展方向。针对当前研究存在的局限,建议研发低成本高灵敏传感器并构建全周期智能预警平台,为松材线虫病的科学防控提供理论依据与技术参考。

Abstract:

Pine wilt disease(PWD),characterized by rapid onset and high mortality rate constitutes a severe threat to forest ecological security in China.Consequntly,the timely and accurate monitoring of infected trees is imperative for mitigating its spread..Centered on the physiological and morphological attributes of PWD-infected pine trees across varying disease stages(early,middle,late,and terminal),this paper systematically reviews the monitoring principles and research progress in remote sensing unmanned aerial vehicle(UAV)remote sensing,and multi-source remote sensing data fusion technologies.The analysis reveals that while remote sensing exhibits distinct advantages in large-scale macroscopic surveys of infected trees at the middle,late,and terminal stages,its efficacy in detecting faint early-stage signals is hampered by constraints in spatial,temporal,and spectral resolution.UAV-based visible-light and multispectral remote sensing combine high spatial resolution with relatively cost-effectiveness for middle- and late-stage monitoring,however,they frequently fail to capture early physiological stress signals.Conversely,UAV hyperspectral remote sensing,benefiting from its continuous narrow-band characteristics,serves as the most potent approach for discerning subtle spectral changes at the early stage,despite challenges associated with high cost and complex data processing.By integrating multi-dimensional spatiotemporal information,multi-source remote sensing data fusion can mitigate the limitations inherent in individual data sources,representing an important development direction for achieving fine-scale,full-cycle monitoring of infected trees.Finally,considering the limitations of existing studies,this paper outlines future perspective on the development of low-cost,high-sensitivity sensors and the construction of full-cycle intelligent early-warning platforms,providing theoretical support and technical references for the scientific prevention and control of pine wilt disease.
