| 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.
