The importance of urban soil condition for tree roots to survive and function in conspicuously hostile built environments has received limited attention. In part, this is because investigating root systems around buildings and hardscapes is fraught with logistical challenges. The goal of this research program is to advance urban tree protection by developing procedures for precisely determining root locations. Such knowledge can inform strategies that lead to greater success in preserving urban trees and the extensive benefits they provide to cities. Urban forests are now widely recognized as an essential contributor to the sustainability of cities and urban quality of life. They provide varied and substantive ecosystem services that include economic, social and environmental benefits (e.g., moderating urban temperature, sequestering atmospheric carbon dioxide, mitigating storm water runoff, and enhancing mental well being). To address limitations that currently limit knowledge of tree root location in urban areas, my research group will advance novel non-invasive methods that take advantage of ground penetrating radar (GPR) to locate urban tree roots, quantify their size, and construct detailed three-dimensional root morphology maps. In this research program, we will develop an automated root detection approach to processing GPR scans for tree root, calibrate and verify its accuracy through physical excavation of roots. Moreover, this research will refine selection and use of GPR hardware, including antenna frequency, and data collection methods for effective and accurate root detection. Ultimately, this research program will contribute to the greening of cities by providing developers, landscape architects and arborists with new tools to more carefully design and redesign the built environment to ensure the resilience of urban trees.********

城市土壤条件对于树根在明显恶劣的建筑环境中生存和发挥作用的重要性受到的关注有限。在某种程度上，这是因为调查建筑物和硬景观周围的根系充满了后勤挑战。该研究计划的目标是通过开发精确确定根位置的程序来促进城市树木保护。这些知识可以为保护城市树木及其为城市带来的广泛利益提供更大成功的策略提供参考。城市森林现在被广泛认为是城市可持续发展和城市生活质量的重要贡献者。它们提供各种实质性的生态系统服务，包括经济、社会和环境效益（例如，调节城市温度、封存大气二氧化碳、减轻雨水径流和增强精神健康）。为了解决目前限制城市地区树根位置知识的局限性，我的研究小组将提出新颖的非侵入性方法，利用探地雷达（GPR）来定位城市树根，量化其大小，并构建详细的三-维根形态图。在这个研究项目中，我们将开发一种自动根部检测方法来处理树根的探地雷达扫描，通过根部的物理挖掘来校准和验证其准确性。此外，这项研究将完善探地雷达硬件的选择和使用，包括天线频率和数据收集方法，以实现有效和准确的根部检测。最终，该研究计划将为开发商、景观设计师和树木学家提供新工具，以更仔细地设计和重新设计建筑环境，以确保城市树木的恢复能力，从而为城市绿化做出贡献。********
