| 摘 要： | 地下水是水资源的重要组成部份,地下水污染危害人的健康,影响人们的生产和生活,查明某一地区地下水容易受污染的可能性即地下水脆弱性,能为管理决策部门提供合理开发地下水资源,防治地下水污染的科学规划和管理依据。在脆弱性评价工作中,应用GIS技术完成地下水系统脆弱性编图,并进行地下水环境保护功能分区,是查明某一示范区地下水脆弱性的可靠手段和科学依据。本文以河北省沧州地区为例,以DRASTIC模型的七项评价因子为脆弱性评价指标,利用MAPGIS为平台实现地下水脆弱性编图,方便从事地下水工作的管理人员及时掌握地下水污染动态、空间分布及演化趋势。

| Abstract: | Groundwater is an important component of the water resources.Groundwater pollution endangers human health and affects people’s production and life.Thus identifying the possibility of groundwater pollution in an area,which is the groundwater vulnerability,can provide rational scientific planning and management basis for exploitation of groundwater resources and control of groundwater pollution for management decisions sector.In vulnerability assessment,applying GIS to complete the mapping of groundwater system vulnerability and to zone the groundwater environmental protection function division is the reliable tools and scientific basis to identify the groundwater vulnerability of a demonstration area.This article bases on the groundwater vulnerability assessment in Cangzhou of Hebei as an example,uses seven evaluation factors of DRASTIC model as the vulnerability assessment indicators,utilizes MAPGIS platform to realize the groundwater vulnerability mapping,and facilitates the management working in groundwater to master groundwater pollution dynamic,spatial distribution and evolution timely. |
