摘　　要：为提高传统淤地坝规划设计水平和效率,基于现有的黄土高原小流域基础数据,运用"3S"技术、计算机图形技术、数据库技术、虚拟现实技术等,开发了小流域坝系规划三维可视化决策支持系统,实现直观、准确、快速的坝系规划。该系统充分考虑了坝系规划设计的实际业务特点,开发了坝系规划核心业务流程中的10多个关键自动算法,实现了三维可视化环境下流域现状的真实感模拟、坝系规划实时计算与动态显示以及坝系工程未来生态效果预测模拟,有效提高了坝系规划辅助的自动化程度,减轻了坝系规划人员繁重的计算工作量,并已应用于山西省太原市娄烦县雷家庄小流域的坝系可研规划。Based on watershed data,“ 3 S” technology,computer graphics,data base and virtual reality technology,the Warping Dams Plan System was developed to improve traditional dam plan method. The system could simulate real scene of small watershed and realize the real-time computing. Meanwhile,in view of warping dams plan5 s real characteristics,the system developed a dozen key automatic computing algorithms. Finally, the realtime calculation and dynamic display of the actual simulated dam system and the prediction simulation of the future ecological effect of the dam project were realized and improved the efficiency of warping dams plan. At present,the system has been applied to the watershed dams plan in Loufan County of Shanxi Province.
