摘　　要：地下水是我国重要的水资源,当前我国面临的地下水污染防治形势较为严峻.开展地下水污染风险评价及预警是预防地下水污染的有效措施,目前国内外有关地下水污染预警方面研究尚处于探索阶段,未形成一套完善的、可供借鉴的技术方法.本研究在分析不同尺度地区地下水污染预警工作需求的基础上,筛选出区域(流域)尺度地下水污染预警指标,包括地质介质防护性能、污染源特征、地下水动态及地下水价值因素四项指标,并利用指标叠置法建立了地下水污染预警模型.以包头平原区为例,开展了地下水污染预警研究,利用建立的模型划分了不同等级的地下水污染预警分区,研究成果可为当地地下水资源管理部门提供科技支撑.Groundwater is the main source of water supply in China,and China＇s overall situation of groundwater pollution is not optimistic at present. Groundwater pollution risk evaluation and early-warning are the effective measures to prevent groundwater pollution. At present,research of groundwater early-warning method at home and abroad is still at the exploratory stage,and the sophisticated technology has not been developed for reference. This paper briefly described the data and technological demand of the early-warning method in different scales,and the main factors influencing the early-warning results of groundwater pollution were classified as protection performance of geological medium,characteristics of pollution sources,groundwater dynamics and groundwater value. Then the main early-warning indexes of groundwater pollution were screened to establish the early-warning model of regional or watershed scale by the index overlay method. At last,the established early-warning model was used in Baotou plain,and the different early-warning grades were zoned by the model. The research results could provide scientific support for the local management department to protect the groundwater resources.
