摘要
为分析地下水水质的时空变化规律,研究基于GIS技术与动态监测数据库的地下水质量可拓评价模型。采用可拓分析方法,将地下水水质级别、评价指标及其特征值作为物元,根据地下水环境质量分级标准建立关联函数,通过计算综合关联度判断地下水环境质量级别,用克立格插值方法生成地下水质量分区图。在MS VC++6.0环境下,利用MapGIS6.5二次开发函数库,开发了地下水质量可拓评价模型。模型界面易于用户操作,可用于区域地下水质量的综合评价,有助于地下水资源的管理。
In order to analyze the groundwater quality changes with the time and space, the groundwater quality extension evaluation model based on GIS technology and the dynamic monitoring database are studied. The authors illustrate extension method that takes the grade of groundwater quality, index of evaluation and its characteristic value as mater elements, Correlated function is established based on the grade of groundwater quality and then the grade is calculated by the comprehensive correlated degree. Adopting Kriking value-inserting method, the map of groundwater quality zoning can be generated. With MS VC + + 6.0 and MapGIS 6.5 secondary development functions, the groundwater quality extension evaluation model can be developed. The model interface is easy to operate and can be used for comprehensive evaluation of the regional groundwater quality. It is helpful for the groundwater resources management.
