- 摘要:
- 以泾惠渠灌区为典型研究区，通过搜集并分析当地降水、蒸发等气象资料，利用ArcGIS 9.3软件对研究区1984年、2002年及2008年3 a的埋深数据进行分析，并绘制了矢量化的研究区域控制范围图，以此进一步确立了研究区的水文地质条件及其边界条件等。将2008年、2009年资料导入地下水模拟软件Visual Modflow中，通过已有的资料建立地下水三维数值模型，再通过模型的迭代计算出适合该研究区的水文地质参数，最后根据当地实际环境，假定出两种合理方案并进行模拟，选出合理方案以此来建立评价和量化地下水资源及可持续利用的方法、调控方式和指标体系，为流域水资源优化配置和综合利用提供决策支持。
- Abstract:
- This paper took Jinghui irrigation zone as an example. By collecting and analyzing the local meteorological data(precipitation, evaporation), and ArcGIS 9.3 software was used to analyzed the buried depth data of the study area in three years of 1984, 2002 and 2008, and the vector quantization control diagram of research area was made in order to further establish the hydrogeologic condition and boundary condition, etc. Taking data of 2008 and 2009 into Visual Modflow groundwater simulation software, three-dimensional numerical model of groundwater was established based on the existing data, and then the more suitable hydrogeological parameters for study area were calculated through the model iterative. By assuming the two kinds of reasonable solution and simulated according to the local actual conditions, the reasonable scheme was chosen to establish reasonable evaluation and quantification of sustainable utilization of groundwater resources and method, regulation and index system, and then provide decision support for comprehensive utilization and optimal allocation of basin water resources.
