Enhancing the understanding of canopy biodiversity: Estimating forest canopy surface temperature by airborne laser scanning, thermal infrared scanning, and 3D radiation modeling

温度是影响植物生长和昆虫丰度与多样性的重要物理因子之一。由于许多类群，如鸟类和蝙蝠以昆虫为食，昆虫的存在和模式是整体动物物种多样性的重要组成部分。该建议旨在评估和分析森林冠层的空间和时间温度分布，并在生物多样性探索站的非管理和管理森林实验区（EP/VIP）的案例研究中研究森林管理/森林结构与温度分布之间的关系。安装在通量塔上的热红外摄像机提供了森林树冠层的高空间分辨率表面温度图像。林冠内的温度变化将使用三维辐射传输模型进行模拟。航空遥感传感器（热红外和激光扫描仪）方法的应用和发展将使这些调查结果能够外推到EP/VIP和更大的森林地区。

Temperature is one of the most important physical factors influencing the growth of plants and abundance and diversity of insects. Because many taxa such as birds and bats feed on insects, presence and patterns of insects are important constituents of overall faunistic species diversity. This proposal aims at the assessment and analysis of spatial and temporal temperature distribution in forest canopies and research into the relationships between forest management/forest structure and temperature distribution in case studies of unmanaged and managed forest experimental plots (EP/VIP) of the Biodiversity Exploratories. A thermal infrared camera installed at flux towers delivers high spatial resolution surface temperature images of the forest canopy. The temperature variation inside the forest canopy will be simulated using 3D radiative transfer modeling. The application and development of methods for airborne remote sensing sensors (thermal infrared and laser scanner) will allow extrapolation of these findings to EPs/VIPs and to larger forested areas.
