| 摘 要： | 本博士论文在前人构建的陆面水文过程模型TOPX和区域气候模式RIEMS的耦合模式的框架基础上，针对耦合模式中RIEMS对降水和蒸散发的模拟精度较低，RIEMS和TOPX模式之间尺度不匹配等几个核心问题进行了深入细致的研究:对天气雷达资料的定量估测降水方面的研究获得了对沂沭河流域最佳的Z-R关系，并通过雷达雨量计联合校正法得到较高精度的面降雨量；采用集合卡尔曼滤波同化算法对雷达反演的面雨量及区域气候模式RIEMS的降水输出进行了数据同化方案研究，获得了更好的降水模拟效果；在RIEMS和水文模型TOPX构成的耦合模型中加入同化方案，实现了流域降水的实例模拟研究，结果表明使用同化方案明显改善了水文模拟效果。

| Abstract: | This paper aims at data structure of line map symbols.Firstly,graphic composition pattern and rendering efficiency in three classic structures of line symbol which contained cell-cycle,line-type overlay and function method were analyzed.Secondly,a structure and storage method based on PostScript imaging model were proposed for uniformly describing control axis in line symbols.Thirdly,three types of strokes which contained color-stroke,cell-stroke and raster-stroke were designed.They supported the two compos... |
