摘　　要：成都市龙泉山地质结构极为复杂,但具有优越的区位优势,是全球最大的城市绿心,如何充分利用成都市龙泉山各类地质数据,通过数据耦合的方式建立地质地下空间三维地质模型是支撑龙泉山城市森林公园地下地质空间信息系统建设的关键,这对于优化龙泉山城市森林公园布局、提升公园品质、提高公园管理效率,有效服务于龙泉山城市森林公园的规划建设和运营管理具有重要意义。本文结合龙泉山复杂地质体特征,从三维建模的角度借助三维GIS(Geographic Information System,GIS)的可视化技术,研究了一套可用于复杂地质体三维地质建模的流程和技术方法,并构建三维实体模型。The geological structure of Longquan Mountain in Chengdu is extremely complex,but it has superior location advantage and is the largest urban green center in the world,it is the key to support the construction of underground geo-spatial information system of Longquanshan City Forest Park to establish the geo-spatial 3D geological model through data coupling.lt is of great significance to optimize the layout of Longquan Mountain Urban Forest Park,improve the quality of the park,the management efficiency of the park,and effectively serve the planning,construction and operation management of Longquan Mountain Urban Forest Park.Based on the characteristics of complex geological body in Longquan Mountain,this paper studies a set of technical methods and processes for 3D geological modeling of complex geological body by means of 3D GIS(Geographic Information System,GIS)visualization technology from the angle of 3D modeling,and Constructs 3D solid model.
