  • 用激光雷达样本训练卫星模型,实现全美森林结构估算
  • 在稀疏和密集林区均减少预测偏差,避免高估或低估
  • 每年更新,适合森林与火灾风险的精细化管理

遥感技术日益用于大尺度森林与火灾风险管理。持续需要覆盖全域、年度更新的森林地图。现有规划系统常整合来源各异、时效不同、精度不一的数据,导致决策系统行为混乱。本文提出VibrantForests框架,将国家森林清查、机载激光雷达与卫星影像融合,应用于美国本土,以10米分辨率同步生成冠层覆盖度、冠层高度、地上活树生物量、断面面积和平方平均直径等森林属性。模型在从稀疏到密集林区的全谱森林条件下均表现良好,显著扩展了同类被动传感器模型的饱和阈值范围,并有效缓解了回归均值问题——该问题常导致小范围/稀疏区域高估、大范围/密集区域低估。VibrantForests框架通过提供一致的全域年度10米级森林属性估计,解决了大区域森林与火灾规划中的关键瓶颈。

原文摘要 · Abstract (English)

Remote sensing is increasingly relied upon to deliver actionable science for forest and wildfire risk management across large landscapes. Wall-to-wall, annually updated maps are a persistent need for effective forest management. Many planning systems and data collections combine disparate data sources with different purposes, vintages, and prediction quality, which leads to confounding behavior in operational planning systems. We introduce the VibrantForests framework, developed and applied to map forest attributes and provide a coherent foundation for effective forest and wildfire planning. VibrantForests includes a satellite-based forest structure model trained on lidar-derived samples and applied across the contiguous United States to concurrently generate estimates of canopy cover, canopy height, aboveground live tree biomass, basal area, and quadratic mean diameter at 10-meter resolution. We demonstrate predictive capability spanning the full spectrum of forest conditions ranging from sparse-canopy/low-biomass to dense-canopy/high-biomass. Results show that our model extends the range at which saturation is commonly encountered in comparable passive-sensor models, and reduces regression-to-mean behavior that commonly produces overestimation of forest attributes in small/sparse conditions and underestimation in large/dense conditions. The VibrantForests framework addresses a key limitation in large-area forest and wildfire planning by delivering coherent wall-to-wall estimates of management-relevant attributes at annual cadence and 10m resolution.
