摘　　要：以农业生产区域为研究对象,利用三维GIS平台VRMap 3.0作为视景驱动工具,综合应用三维建模、数据库和GIS技术,提出了一种快速建立农区三维虚拟场景的方法,并开发了基于VRMap的农区可视化仿真系统,系统具有场景管理、场景浏览、信息查询、空间分析和景观切换等功能。以江苏省姜堰市河横村和南京市青龙村为案例区,对系统进行了初步的实例应用,表明系统能实现农区空间信息的有效管理和虚拟显示,符合现代农区信息服务的发展需求,为新农村建设与管理提供了数字化平台。Taking agricultural production region as the research object,a methodology for quickly constructing the three-dimensional virtual scene of agricultural region was proposed by using VRMap 3.0 as the driver of scene, and integrating technologies of 3D modeling, database and GIS. A VRMap-based agricultural region visualization simulation system was developed with the functions as scene management, scene browse, information query, spatial analysis and scene switch. Case studies on the experimental system were carried out in Heheng Village of Jiangyan City and Qinglong Village of Nanjing City in Jiangsu Province. The results revealed that the presented system realized the effective management and virtual display of spatial information, accorded with the development requirement for modern agricultural information services, and could provide a digital platform for the construction and management of new countryside.
