三维地籍模型构建与应用研究

Research on the Construction and Application of 3D Cadastral Model

地籍是土地的“户籍”,是国家管理土地资源和资产的工具,对明确土地权属关系、维护土地市场正常秩序等具有重大的意义。随着城市发展纵向化与土地利用立体化趋势的增强,现有以地表权利为核心的二维地籍显然已经无法满足目前地籍管理工作的需求。针对同一宗地,土地使用权需要在地表、地上、地下分别设立,所以需要将土地权转化为空间权,实现对地上、地下空间开发利用管理也是地籍管理系统发展的必然趋势。因此,该研究可为三维地籍可视化研究领域提供一种可行性的方法,对其他省市的相关三维地籍项目有借鉴价值和指导意义。

Cadastre is the"household registration"of land and a tool for the state to manage land resources and assets.It is of great significance to clarify the relationship of land ownership and maintain the normal order of the land market.With the vertical development of the city and the enhancement of the three-dimensional trend of land use,the existing 2D cadastre with land surface rights as the core has obviously been unable to meet the needs of the current cadastral management.For the same land,the land use right needs to be set up on the surface,above ground and underground respectively,so it is necessary to transform the land right into space right,and it is also the inevitable trend of the development and utilization of the cadastral management system to realize the development and utilization management of the above ground and underground space.Therefore,this study provides a feasible method for the field of 3D cadastral visualization,and has reference value and guiding significance for the relevant 3D cadastral projects in other provinces and cities.
