摘　　要：根据北京市的水文地质条件,阐述了中深层地下水位的变化趋势及降落漏斗的形成和演化。由于中深层地下水是生活和工业用水的主要水源,它的补给条件差,80%靠浅层水的越流补给。长期地下水监测资料表明,因不合理开采,已造成水位过度下降,漏斗面积不断扩大,局部水质恶化等环境地质问题。提出了相应防治措施,严格控制地下水资源开采,与地表水联合调度。based on hydrogeologic condition in the study area, the article analyses the cause and trend of the groundwater level changing in the Beijing plain, and studied the formation and evolvement of the groundwater depression. Because the mid/deep groundwater is the mainly water resource, which is supply living and industry. It＇s recharge condition is very poor. Eighty percents of mid/deep groundwater is supplied by shallow water. Longperiod groundwater monitoring data show that irrational exploitation has caused many environmental geological problems, such as water level excessive descend, funnel area expend and local water quality changes. Finally, some preventive measures are proposed.
