摘要

模拟太阳辐射穿过林冠的光谱透射率的物理模型是研究短波辐射环境与林地生产力和生物多样性之间联系的有用工具。我们报告了对两种模拟森林冠层光谱透射率方法的综合评估。这两种方法分别是：(i) 由充满浑浊介质的单个树木组成的树冠中的三维辐射传递建模；(ii) 光子再碰撞概率理论（p 理论），并分别使用 DART-FT 和 PARAS 模型实现。模拟结果与中欧和北欧各地森林地块晴空条件下测得的树冠透射光谱的平均值和标准偏差进行了对比评估。总体而言，两个模型都与现场测量结果吻合。它们在针叶林中的表现相当，而在阔叶林中，PARAS 的精确度略低于 DART-FT。我们的结论是，在本研究测试的空间尺度上，这两种方法都能对树冠光谱透射率进行逼真的模拟，而且 p 理论是三维辐射传递的一种计算效率高、易于参数化的替代方法。

期刊介绍： A British Ecological Society journal, Methods in Ecology and Evolution (MEE) promotes the development of new methods in ecology and evolution, and facilitates their dissemination and uptake by the research community. MEE brings together papers from previously disparate sub-disciplines to provide a single forum for tracking methodological developments in all areas. MEE publishes methodological papers in any area of ecology and evolution, including: -Phylogenetic analysis -Statistical methods -Conservation & management -Theoretical methods -Practical methods, including lab and field -This list is not exhaustive, and we welcome enquiries about possible submissions. Methods are defined in the widest terms and may be analytical, practical or conceptual. A primary aim of the journal is to maximise the uptake of techniques by the community. We recognise that a major stumbling block in the uptake and application of new methods is the accessibility of methods. For example, users may need computer code, example applications or demonstrations of methods.
