由于其异质性和难以进入，研究森林地下是一项挑战。生态学家用来描述地下特征的传统方法空间代表性较低。这篇评论文章阐述了地球物理技术如何能够并且已经被用来获得对森林生态学的新见解。近地表地球物理学提供了多种方法以非破坏性和综合的方式表征地下特性的空间和时间变化，每种方法都有其自身的优点和缺点。这些技术可以单独使用，也可以结合使用，以发挥其互补性。我们的审查使我们定义了近地表地球物理学如何支持森林生态学研究的三个主题：1）根系检测，2）水量和动态监测，以及3）林分水平地下特性的空间异质性特征。利用近地表地球物理学进行的森林生态学研究数量正在增加，这种多学科方法为改进生物物理特性的定量评估和探索森林对环境的响应和对气候变化的适应开辟了新的机会和视角。
Studying the forest subsurface is a challenge because of its heterogeneous nature and difficult access. Traditional approaches used by ecologists to characterize the subsurface have a low spatial representativity. This review article illustrates how geophysical techniques can and have been used to get new insights into forest ecology. Near-surface geophysics offers a wide range of methods to characterize the spatial and temporal variability of subsurface properties in a non-destructive and integrative way, each with its own advantages and disadvantages. These techniques can be used alone or combined to take advantage of their complementarity. Our review led us to define three topics how near-surface geophysics can support forest ecology studies: 1) detection of root systems, 2) monitoring of water quantity and dynamics, and 3) characterisation of spatial heterogeneity in subsurface properties at the stand level. The number of forest ecology studies using near-surface geophysics is increasing and this multidisciplinary approach opens new opportunities and perspectives for improving quantitative assessment of biophysical properties and exploring forest response to the environment and adaptation to climate change.
