基于GIS技术设计开发地下水功能评价模型系统。应用GIS叠加分析方法,将参与评价的空间图层要素叠加,以叠加后形成的图元为基本单元,参考地下水功能评价技术要求,进行地下水功能评价,将评价结果进行归并,得出地下水功能评价系列分区成果图。在VC++6.0下,应用MapGIS二次开发函数库,开发了地下水功能评价模型系统,作为地下水资源调查信息系统的有机组成,评价结果可交信息系统管理及进一步利用。
Designing and developing groundwater function evaluation model system based on. Applying the GIS overlay analysis method, the spatial layer elements involved in evaluation are superimposed, and the primitives formed by the superimposition are taken as basic units. Groundwater function evaluation is performed with reference to groundwater function evaluation technical requirements, and the evaluation results are combined to obtain the groundwater function evaluation Series partition results. Under VC ++ 6.0, the MapGIS secondary development function library was used to develop the groundwater function evaluation model system as an organic component of the groundwater resources survey information system. The evaluation results can be submitted to the information system management and further utilization.
