流域干旱演化模拟与评估数字仿真系统研发

Development of the digital simulation system of drought evolution simulation and assessment in a basin

以新疆玛纳斯湖流域为例,将多源数据管理、干旱模拟评估、信息直观表达等技术相融合,研发了流域旱情演化与评估数字仿真系统。该系统具有多模式控制漫游、时空数据查询与显示、实体信息查询与显示、文字动态标注、多媒体仿真等基础功能,提供了干旱指数计算、干旱演化参数图形表达、干旱数据空间插值、干旱演化时空动态可视化等专业功能。

Taking the Manasi Lake River Basin as an example, a digital simulation system Platform of Drought Evolution Simulation and Assessment in a basin was developed. The key techniques used in the system development included multi-source data management, drought evolution simulation and assessment and information intuitive expression. The system not only provided the basic functions, e.g., multi-mode roaming control, spatial-temporal data query and display,water infrastructure information query and display, dynamic text annotation, and multimedia simulation, but also coved professional functions, e.g., drought in- dex calculation, graphics expression of drought evolution parameters, spatial data interpolation, and dynam- ic visualization of drought evolution process.
