地下水水质调查是研究地下水资源状况的基本工作,是地下水水质评价、地下水承载力研究、地下水污染研究等工作的基础性工作。运用系统工程和软件工程,将新技术PDA和3S集成技术引入这一工作领域,构建了基于3S的地下水水质调查评价模型,并进行了系统设计和系统实现。并在陕西省泾惠渠灌区地下水水质调查与评价工作中运用,较传统方法工作量小,调查精度高,评价结果可靠,数据管理可持续性强,提高了地下水水质调查与质量评价的工作效率。
Groundwater quality survey is to study the status of groundwater resources, basic work, groundwater quality evaluation, groundwater carrying capacity research, groundwater pollution research work of the basic work. Using system engineering and software engineering, new technologies PDA and 3S integration technology are introduced into this work area, and a groundwater quality survey and evaluation model based on 3S is constructed, and system design and system implementation are carried out. And it is used in the investigation and evaluation of groundwater quality in Jinghuiqu Irrigation District in Shaanxi Province. Compared with the traditional methods, the workload is small, the investigation accuracy is high, the evaluation results are reliable, the data management is more sustainable and the working efficiency of groundwater quality survey and quality evaluation is improved .
