摘　　要：针对2维房产管理中的产权重叠、表达不完全和建筑物室内外一体化管理难题,在综合分析3维房产数据的对象类型及其应用特性的基础上,从概念层次提出了一种基于语义的多细节层次3维房产模型。该模型通过空间与产权的语义描述,对3维房产管理对象间的多细节层次关系进行一体化表达,特别是实现了对建筑物内部的房产空间关系表达,有利于明晰内部空间(户)的产权划分及各房产对象间的产权关联,为建立产权明晰与室内外综合管理的真3维房产应用提供了理论依据。Based on comprehensive analysis of 3D property right objects and various application characteristics, in this paper, a novel conceptual model is proposed for solving the problems of integrated management and reg istration of overlapping and interlocking buildings and their interior property situations in real 3D environment, which consists of two aspects： the semantic description of spatial entity and related property right, and 3D hierarchical framework （Levels of Detail： LOD） for the integrated representation of indoor and outdoor proper ty right objects. The conceptual model can describe the actual relationships among property right objects espe cially for the integrated management of indoor and outdoor objects, and represent complex interior space of real 3D property right for the increasing complex buildings. Theoretical analysis proves this model provides insight in the vertical dimension of property rights, and plays an important role in improving real 3D house property management research.
