Three-dimensional Modeling for Aboveground and Underground Integration of Soil and Water Conservation Demonstration Park

[目的]探讨水土保持生态科技示范园三维建模的流程和方法,以期为后续数字园区建设奠定基础。[方法]基于园区GPS测绘以及地面调查数据,将可视化建模技术应用于水土保持工程中。[结果]以江西省水土保持生态科技园为例,运用约束三角剖分和空间插值等技术,解决了地物与地形的无缝拼接、土壤实体建模、植物模型快速生成等关键问题,最终构建了包含工程措施、植被、土壤等要素的园区地上下一体化三维模型。[结论]开发的三维可视化系统,可以更好地发挥水土保持生态示范园区的科学支撑、社会宣传、典型带动和示范辐射作用。

[Objective] Through studying three-dimensional（3D） modeling processe and method, we expected to provide solid basis for subsequent building of digital park. [Methods] Based on GPS mapping and ground survey of the park, visualization modeling was applied to the soil and water conservation project. [Results] Jiangxi Soil and Water Conservative Ecological Science and Technology Park was taken as an example, constrained triangulation and spatial interpolation were employed to solve some key issues. For example, seamless tiling of surface features and topography, soil body modeling, rapid generation of plant model, and so on. Finally a 3D model with aboveground and underground integration system including such elements as project measures, vegetation, and soil, etc., was constructed. [Conclusion] The developed 3D visualization system can make the water and soil conservative ecological demonstration park playing a better role in scientific support, social promotion, typical drive and demonstrative radiation.
