【摘要】 水资源是发展国民经济不可缺少的重要自然资源。在水质污染问题中,地下水水质污染日趋严重。水质污染导致的直接后果就是可利用资源量日渐减少,加剧了水资源供应危机,直接影响工农业的生产和国民经济的发展,对生态系统和人类健康造成危害。曹妃甸地处唐山南部的渤海湾西岸,位于天津港和京唐港之间,为大型深水港口建设和临港产业发展提供了优越条件。其特殊的地理位置,决定了它在我国国民经济发展中的重要性,也决定了该区地下水脆弱性评价的重要性。论文研究的主要内容如下：1.分析和总结了目前国内外地下水脆弱性的概念、影响因素以及评价方法的研究现状和水平,指出了目前地下水脆弱性研究存在的一些问题。2.在分析和研究了曹妃甸地区地质、地貌和水文地质条件等自然地理条件的前提下,综合曹妃甸地区地下水开采利用和地下水污染现状,提出适合研究区的地下水脆弱性评价方法。3.建立地下水脆弱性评价体系和评价标准,选用DRASTIC和模糊综合评价两种方法评价该区域地下水的脆弱性。4.利用了MAPGIS编制了曹妃甸地区地下水脆弱性评价图以及影响因素系列图,为实行地下水的保护和管理提供了科学依据。5.对DRASTIC和模糊综合评价两种方法及价结果进行比较,编制曹妃甸地区地下水脆弱性评价图。更多还原

【Abstract】 Water is to develop the national economy indispensable important natural resources. In water pollution problems, groundwater pollution becomes more and more serious. Water pollution caused available resources dwindling, increased supply of water, and directly affects the crisis of production and development of national economy, of ecosystem and human health hazard. CaoFeidian located in the southern boa bay Tangshan, located in Tianjin and west JingTang haven for large deep-water port, between the construction and development of port-vicinity industry provides superior conditions. Its special geographical position, determines its development of national economy in China, the importance of the groundwater vulnerability to the importance of the evaluation.The main thesis reads as follows:Firstly, this paper analyzed and summarized the current situation of the concept, classification, influencing factors, and assessment methods on groundwater vulnerability at home and abroad, and pointed out some problems existed in groundwater vulnerability researches.Secondly, this paper analyzed and studied of the CaoFeidian geological, geomorphological and hydrogeological conditions of the premise of natural and geographical conditions, comprehensive exploitation of groundwater and groundwater pollution situation in CaoFeidian, putting forward the groundwater vulnerability assessment method for the study area.Thirdly, the establishment of groundwater vulnerability assessment system and evaluation criteria, selection DRASTIC and fuzzy mathematics is two ways to evaluate the region vulnerability in groundwater.Fourthly, prepared using the MAPGIS to work out the CaoFeidian vulnerability maps of groundwater and the factors series map for the implementation of groundwater protection and management provide a scientific basis.Fifthly, the evaluation methodology and the results of DRASTIC and Fuzzy Mathematics Method were compared, and drawing the CaoFeidian vulnerability map of groundwater.更多还原
