基于GIS的地下水资源开采潜力评价模型设计与实现

Based on GIS: Model of Groundwater Resources Exploitation Potentiality Evaluating

为辅助专业人员进行地下水资源开采潜力分析评价,采用“单位面积数量”指标,以地下水资源空间数据库为基础,利用GIS迭加分析方法,设计地下水资源开采潜力评价模型。基于MAPGIS 6.5二次开发函数库,在VC++6.0环境下开发地下水资源开采潜力评价软件。软件界面易于操作,可根据具体情况选择评价指标,评价数据来源于空间数据库,评价结果又以空间数据的形式保存,还能可视化表达。

For helping professional personnel analyse and evaluate the groundwater resources exploitation potentiality, a model of groundwater resources exploitation potentiality evaluating is designed with the index of quantity of unit＇s area being adopted, GIS overlay analytical method being used and the space database of groundwater resources being taken as the basis. Based on MAP（IS 6.5 secondary development function LIB, the groundwater resources exploitation potentiality evaluation software has been developed under VC ＋＋ 6.0 environments. The software interface is easy to operate, can choose the evaluation index according to the concrete conditions. The data used for evaluation stem from space database, and the results are kept in the form of space data.
