摘　　要：土地空间权的分层设立与产权的精细化管理使得地籍管理模式由二维地籍转向三维地籍,而产权体作为三维地籍的登记客体,对其语义、几何等属性进行限定是构建三维地籍的基础。通过分析产权体的语义、几何特征,给出产权体的定义,提出采用三维流形限定产权体的几何形体,进一步建立了可表达具有复杂几何形体产权体的空间数据模型。Stratified establishment of land space right and fine management of property rights make cadastre managing mode change from two-dimensional （2D） cadastre to three-dimensional （3D） eadastre. As registration object of 3D cadastre,restrietions of semantics and geometry of property volume are the basis to construct 3D cadastre. Through the analysis of the semantic and geometrical characteristics of the property volume, this paper gives its definition, and proposes the further establishment of the spatial data model suitable for representing the property volume with com- plex geometrical shape by using three-manifold to restrict its geometrical shape. Experiments prove the proposed theory and model effective and feasible.
