树木的根系是如何在底土中生长的？这个问题对发展和城市规划学科很重要，特别是当树木出现在建筑物地基和地下设施附近时。这种兴趣是基于建筑物可能遭受附近树木的沉降或结构损坏。树根的延伸和木材腐烂程度的检查仍然使用经典的单点和破坏性方法进行。然而，正如几位作者所指出的，地球物理方法提供了一种以非侵入性方式研究根构型的替代方法。在本文中，三个地球物理方法被应用到产生在城市环境中的土壤中的总根体积的3D图像。使用的三种地球物理方法是探地雷达、电阻率层析成像和地震折射层析成像。每一种地球物理方法都能单独分离出根系，但不能分辨出环状结构。
How does the tree root system develop in the subsoil? This question is important to the development and urban planning disciplines, especially when the trees occur near building foundations and underground utilities. This interest is based on the potential for buildings to suffer subsidence or structural damage from nearby trees. The inspection of both the extension of the tree roots and the degree of decay in wood are still undertaken using classical single-point and destructive methods. However, as pointed out by several authors, geophysical methods provide an alternative method of studying root architecture in a non-invasive fashion. In this paper, three geophysical methods were applied to produce 3D images of total root volume in the soil in an urban environment. The three geophysical methods used were ground-penetrating radar, electrical-resistivity tomography, and seismic refraction tomography. Each of the geophysical methods alone is able to isolate root system but cannot resolve the ring structures.
