摘要
围绕海平面上升模拟中需解决的水面演进范围判定、进水量计算、水面对象时空数据组织以及水面运动时间动画构建等问题进行了探讨,提出了基于溃堤进水量和改进的有源淹没算法实现的水面演进范围模拟方法,并介绍了如何应用SkyLine软件实现水面上升模拟及其在"数字海洋"中的集成应用。
The problems that exits in the sea surface rise simulation system are discussed in detail, which includes water surface objects and its change, modeling of water inflow, spatio-temporal database schema and time animation of the water surface objects model, etc. Based on the modeling of dam-break water inflow and the improved algorithms for submerged areas calculation with source, a model of water surface objects feature and its moving is proposed in particular. The implementation of this model with SkyLine package and its integration with the China Digital Ocean are also introduced.
