摘　　要：本文旨在解决农村土地确权过程中存在的信息化、智能化管理问题,设计并实现了一个基于二、三维结合的农村土地确权系统。该系统利用二维地图和三维地形模型相结合的方式,实现了对农村土地的全面信息采集和确权管理。本文首先介绍了农村土地确权的背景,以及农村土地确权系统的基本概念,设计了一个具有五层结构的二、三维结合的农村土地确权系统,然后对椭球体表面不规则多边形面积计算、地块图斑界址点自动计算、跨库跨表数据关联分析、统计报表自动生成、三维数据展示及三维地形信息图形化提取等关键技术方法进行了详细描述。最后,本文对该系统功能进行了实现,展示系统界面。该系统通过地理信息系统和三维重建技术,辅助用户在二维地图上标记地块位置,并在三维地形模型上展示土地形状、地貌等信息。同时,系统还提供了数据录入、查询、报表自动生成及批量导出等功能,实现了农村土地确权的全过程信息化管理。因此,该系统能够提高土地确权的准确性和效率,为农村土地确权工作提供有效的支持。This paper aimed to address the issues of informatization and intelligent management in the process of rural land right confirmation,and it designed and implemented a rural land right confirmation system based on the two-dimensional(2D)and three-dimensional(3D)methods.By combining 2D maps and 3D terrain models,the system achieved comprehensive information collection and right confirmation management of rural land.This paper first introduced the background of rural land right confirmation and the basic concepts of the rural land right confirmation system and designed a five-layered rural land right confirmation system combining 2D and 3D methods.It described key technical methods in detail,such as irregular polygon area calculation on the ellipsoidal surface,automatic calculation of patch boundary points in plots,cross-database and cross-table data correlation analysis,automatic generation of statistical reports,3D data display,and graphical extraction of 3D terrain information.Finally,the paper implemented the system functions and demonstrated the interfaces.Using geographic information systems and 3D reconstruction technology,the system assisted users in marking plot locations on 2D maps and displaying land shapes,terrain,and other information on 3D terrain models.Additionally,the system provided functions of data input,data query,and automatic generation and batch export of reports,enabling the comprehensive informatization management of rural land right confirmation.Therefore,this system could improve the accuracy and efficiency of land right confirmation,providing effective support for rural land right confirmation work.
