摘　　要：浅层地热能具有储量大、分布广泛、零污染排放等特点,是可再生绿色能源。通过对河南省水源热泵方式开发浅层地热能时存在成井质量差、水量小、回灌效果差等问题的分析,探讨了浅层地热能开发利用时引起区域地下水位下降与漏斗形成、地面沉降、地下区域性水质污染等环境地质问题,提出应加大地下能源采集和回灌技术的研究,建立浅层地热能监测网等建议。Shallow geothermal energy is a kind of green renewable energy.It has the characteristics of large reserves,wide distribution and zero pollution emission.According to the analysis on the problems of poor quality of well completion,small water quantity,reinjection difficult which caused by shallow geothermal Energy development（water source heat pump） in Henan Province,the paper discussed the environment geology problems of shallow geothermal Energy development,such as regional groundwater level decline and the underground funnel appear,ground subsidence and regional underground water pollution and put forward the suggestions of strengthening the research on underground energy acquisition and reinjection technology and establishing the shallow geothermal energy monitoring network in Henan Province and so on.
