摘　　要：将城市地质调查中的基础地理、工程地质、地球物理、地球化学等数据综合起来进行一体化管理,对城市规划、建设、环境综合评价、公众信息发布具有重要的意义.在通过分析城市地质调查数据的广泛性、多样性、多维性等特点的基础上,对数据进行了分类整理,提出了适合城市三维地质信息管理与服务系统建设的基于勘测点的数据结构模型,这种结构具有简单、易维护、可以满足多层次查询需求等特点.在此基础上结合城市三维地质应用设计了C/S(Client/Server)和B/S(Browse/Server)混合的数据库体系结构,达到了应用的要求.It is essential to manage geological data such as geophysical, geochemical, geotechnical and geographical data in urban planning, construction, environmental evaluation and public information issue. Based on an analysis of the characteristics of city geological data, such as universality, diversity, and multi-dimensionality, this paper classifies the investigations geological data, and proposes a structural data model on the basis of the survey and geodesic dots. It has many characteristics, including simplicity and easy maintenance, and it can be requeried at any level. Based on the data structure, a mixture database system structure is designed, including Client/Server structure and Browse/Server structure, which can realize the professional data processing and maintaining, information publishing and browsing, fit for constructing city 3-dimensional geological information management and service system.
