摘　　要：　通过对豫北平原地下水的综合调查,发现其环境水文地质问题以区域地下水位下降为主,并又导致了泉水消失、湿地减少、地面沉降和地下水污染等次生环境水文地质问题的发生。在环境水文地质问题形成背景和形成条件综合分析的基础上,认为其产生的根本原因是人为活动尤其是地下水的不合理开采破坏了地下水循环系统的天然均衡状态,其演化模式具双向性。最后,提出了减少和防止豫北平原环境水文地质问题的具体措施。An integrated survey of groundwater in the plain of North Henan shows that the regional groundwater lowering is the main environmental hydro-geological problems (EHP) in the areas, which leads to secondary EHP, such as, spring disappearing, moist reducting, ground subsiding and groundwater polluting. On the basis of integrated analysis of the formation background and formation condition of EHP, the basic cause of EHP is that human activities, especially unreasonable groundwater mining, have disrupted the natural balance of groundwater circle system, the evolution pattern of EHP has two direction. The countermeasures to EHP in the areas are put foreword.
