【摘要】 地下水系统动态综合反映了气象、地形、人为活动的影响。基于过程模拟手段揭示地下水的水文功能和变化机制,已经成为水文学研究的重要手段。由于陆地水文系统的非线性,很难全面反映基于过程的地下水水文物理过程,利用ArcGIS简化数据集,既使建立描述时空变异性、多变量和参数化的耦合区域地下水文模型成为可能,又方便与国际通用的分布式地下水文模型集成,符合地下水数字化与世界主流软件一致的要求。依据研究区的水文过程特点,从3个方面阐述了大尺度地下水水文模型构建过程中的主要问题:①大尺度地下水水文模型的结构;②离散化数据集的建立,应用ArcGIS着重分析河流、地形地貌、观测井等主要数据集的建立方法;③数字流域的建立和空间分析手段使得集总式模型和分布式模型实现了很好的结合。更多还原

【Abstract】 Abstract: The groundwater system dynamic state synthesized to reflect the influence of the weather, geography, artificial activity. Simulating means based on process announces hydrology function and changing mechanism of groundwater, it has already become an important means of the hydrology research. Because the land hydrology system is nonlinear, it’s very difficult to overall reflection according to the groundwater hydrology physics process of the process, make use of the ArcGIS can simplification dataset, can make the establishment description space-time variation character, multivariable coupled with parametric underground hydrology model in district turn possible, and convenience with worldwide general use distributed underground hydrology model integration, match the groundwater numerical coherent mainstream software in world. According to the studies area’s hydrology process characteristics, we expound the key problem in the process of large scale groundwater ecosystem hydrology model establishment from three aspects: ① Large scale groundwater hydrology model; ② Establish discrete dataset, applying the ArcGIS to emphasized analyze the terrain and physiognomy, river, weather and observation station and other main datasets establish method; ③ Numerical basin establishment and space analyzed means make lumped model and distributed model identified good.更多还原
