标题： Use of electrical resistivity tomography to map the tree roots

摘要： 一种用于绘制埋藏树根分布的高效高级数值模型被提出。 它不仅将复杂的根系分支简化为易于操作的模型，还抓住了树木根系的主要结构，忽略不必要的细节，从而提供对地下不可见异常的直观印象。 处理模型结合了自适应有限元方法，可以在离散化过程中自动生成非结构化三角形网格，这也使用户能够具体设置树根各部分的电阻率。 显示英文摘要

摘要： An efficient advanced numerical model for mapping the distribution of the buried tree roots is presented. It not only simplify the complicate root branches to an easy manipulated model, but also grasp the main structure of tree roots ignoring the unnecessary minutiae, and thus provide an intuitive impression of subsurface invisible anomalies. The processing model is combined with an adaptive finite element method, which can automatically generate unstructured triangular meshes during the process of discretization, which also enable user to specifically set the resistivity along each part of tree roots.
