The subsurface can be used for a variety of purposes in the urban environment and the subsurface should ultimately be seen as a multifunctional resource, offering a multitude of benefits to humans and the society. Underground construction is commonly planned according to the first come, first served principle and later claims on other resources in the subsurface will have to adapt, often at high costs, or are made impossible. This pilot study is a first step in developing a method aiming to investigate a procedure for mapping an area’s subsurface resources, having the multifunctionality of the subsurface in mind, and integrating this information into urban planning processes. A mapping of the existing resources (supporting, provisioning, regulating, cultural) used at present and their future potential is presented, and an analysis, using an interaction matrix, of how the different subsurface resources can influence each other (conflicts and synergies) if the use(s) changes. Conclusions are that: 1) the concept of geosystem services can strongly support the communication about the subsurface between civil/geotechnical engineers and planners; 2) there is a need at the municipality or city level for systematised and digital 3D archives for easy access to information in relevant format; 3) planning based on the perspective that the subsurface has multiple resources, makes subsurface planning not only a metropolitan issue but also relevant for smaller municipalities. Further work is suggested to: i) explore the concept of geosystem services in a planning context; ii) suggest at which planning level different geosystem services can be optimally managed; and iii) develop tools to support planners for handling subsurface conflicts and acknowledge synergies.

地下可用于城市环境中的多种用途，最终应将地下视为一种多功能资源，为人类和社会提供多种益处。地下建设通常根据先到先得的原则进行规划，随后对地下其他资源的要求必须适应，通常成本很高，或者无法实现。这项试点研究是开发一种方法的第一步，该方法旨在研究绘制一个地区地下资源的程序，考虑到地下的多功能性，并将这些信息整合到城市规划过程中。介绍了当前使用的现有资源（支持、供应、调节、文化）及其未来潜力的映射，并进行了分析，使用交互矩阵，如果用途发生变化，不同的地下资源如何相互影响（冲突和协同作用）。结论是： 1) 地质系统服务的概念可以有力地支持土木/岩土工程师和规划者之间关于地下的交流；2) 直辖市或市级需要系统化和数字化的 3D 档案，以便轻松获取相关格式的信息；3）基于地下具有多种资源的观点进行规划，使地下规划不仅是大都市问题，而且与较小的城市相关。建议进一步开展工作： i) 在规划背景下探索地理系统服务的概念；ii) 建议在哪个规划级别可以对不同的地理系统服务进行最佳管理；
