城市地上地下设施数据一体化研究 ——以南京市为例

从设施分类一体化和数据表达一体化两方面实现地上地下设施数据一体化，进而为推进地上地下一体化开发消除部分障碍。在已有地上地下设施分类国家标准的基础上，结合南京发展实际，对地上地下设施分类进行了融合；并在此基础上，从表达形式和分级控制两方面阐释如何实现设施数据表达的一体化。最终形成的设施数据一体化技术有效促进了地上地下的设施融合，为将地上地下设施作为整体进行统筹考虑做出了一定贡献。

Research on the Key Technologies of Data Integration for Urban Aboveground and Underground Facilities: Taking Nanjing City as an example

The integration of above-ground and underground facilities data can be realized from two aspects: the integration of facility classification and the integration of data expression, thereby eliminating some obstacles for the promotion of integrated above-ground and underground development.On the basis of the existing national standards for the classification of above and underground facilities, combined with the actual development of Nanjing, the classification of above and underground facilities was integrated;And on this basis, it explains how to realize the integration of facility data expression from two aspects of expression form and hierarchical control.Facility data integration technology ultimately promote the effective integration of ground and underground facilities, and make some contribution to the ground and underground facilities as a whole into consideration.
