基于数据库和GIS的水质模糊综合评价模型

摘要

根据地下水污染调查评价的需要,设计并开发了基于地下水污染调查数据库和GIS的水质模糊综合评价模型,该模型将模糊数学理论和数据库管理技术与GIS技术结合,实现了数据录入、管理、评价、制图的一体化流程.通过在实际项目中应用,普遍反映评价界面友好、操作简单、易用,结果符合实际情况,适合区域地下水水质的综合评价,具有较好的推广应用价值.%A fuzzy comprehensive evaluation model of groundwater quality is developed based on GIS technology and the survey database of groundwater pollution to meet the requirements for the evaluation of groundwater contaminatioa The morel combines the fuzzy mathematical theory and the database management approach with GIS technology, and it can fulfill the integration process of data entry,management,assessment and mapping. The model has been applied in many practical projects,which indicates that the model has a friendly interface,an easily hands-on application,and as well as a good agreement with the actual situation. Therefore, this model can be used for the evaluation of regional groundwater quality.
