【摘要】 随着新的城镇地籍建库规范和土地登记办法的相继推出,地籍空间对象的种类和数量被重新划分与确定,三维地籍对象也逐渐加入到地籍空间对象的考虑范畴。研究满足我国地籍管理新需求的地籍空间对象之间的关系,重新建立起合理的地籍空间对象模型,有利于为城镇地籍信息系统的建设提供参考依据。首先,本文采用面向对象的分析方法,详细论述了新规范中规定的地籍空间对象以及对象与对象之间的空间拓扑关系,在此基础上建立了地籍空间对象模型。然后,按照此模型,对地籍变更过程进行设计组织,实现了在宗地变更过程中地类图斑层、房屋层等地上物空间要素联动变更的变更管理策略。其次,本文针对目前地籍管理中急需解决的地下空间使用权登记管理的问题,采用三维地籍空间对象加以解决,在原有二维地籍管理的基础上提出三维地籍对象的降维与简化管理模式,并以此构建了三维地籍对象的降维拓扑分析方法,为在二维地籍信息系统中实现对三维地籍对象的管理提供了一种便捷有效的途径。最后,本文将上述研究成果应用于试验系统中。试验系统运行表明,建立的地籍空间对象模型,清晰地描述了地籍变更过程,针对不同地籍对象的特点提出不同的变更管理策略,有效实现了地籍对象的动态管理。而三维对象的降维简化处理则为在二维空间中解决三维问题提供了简便可行的方法。本文的研究成果对于全国第二次土地调查过程中城镇地籍信息系统的建设具有一定的借鉴意义。更多还原

【Abstract】 With the promulgation of the new Standard for Urban Cadastral Database and the Regulation for Land Registration,cadastral spatial objects have been redefined and reclassified,and it is necessary to take 3D cadastral objects into further consideration.The study of the relationships among cadastral spatial objects based on new demands,and the building of the cadastral spatial object model shall provide useful references for the development of Urban Cadastral Information System.Firstly,the cadastral spatial objects according to the new standard and the spatial topological relationship among these objects are analysed in detail.With the object oriented analysis,the cadastral spatial object model is established,and the course of cadastral spatial change is designed to manage the associated change of cadastral spatial objects in accordance with the changed parcel.Secondly,because of the urgent demand to register subsurface property rights,which are described as 3D cadastral spatial objects,the Dimension Descending and Simplification pattern is proposed to manage 3D cadastral objects,on the basis of traditional 2D cadastral management.And then the dimension descending topological analysis method is put forward to manage 3D cadastral object effectively in 2D cadastral information system,together with the management pattern mentioned above.Finally,the research results are applied to the test system.The operation of the system shows,the cadastral spatial object model describe the process of cadastral change clearly,and establish different management strategies respectively in accordance with their distinguishing characteristics,in order to realize the linkage change and backtracking of the cadastral spatial objects.And the 3D cadastral management pattern also provides a simple and effective way to solve 3D problem in 2D system.It is meaningful to the construction of Urban Cadastral System under the circumstance of the second state land investigation.更多还原
