摘　　要：能源与环境问题是困扰世界各国可持续发展的重大问题,近年来地热资源作为理想的绿色环保能源,发挥越来越重要的作用。北京市地热资源属于沉积盆地型中低温地热资源,目前已有40余年集中开发利用历史。为及时掌握北京市地热资源开发利用潜力,本文在分析北京市构造特征、地热资源类型及地温分布特征的基础上开展了地热资源开发利用潜力评价,构建了基于地热流体开采程度、地热流体热量潜力模数和最大水位降速3个指标的地热资源潜力区划,将北京市地热田分29个评价单元进行了区划,取3个指标中最不利者将其分为严重超采区、超采区、基本平衡区、具有一定开采潜力区、具有开采潜力区和极具开采潜力区6个区,其面积分别为151.45 km^2、631.17 km^2、1341.16 km^2、101.11 km^2、302.72 km^2、14.62 km^2。As an ideal green energy,geothermal resources play an increasingly important role in the world.The geothermal resources in Beijing belongs to low-medium temperature geothermal resources,which is mainly distributed in ten geothermal fields.The focus on geothermal water concentrated development and utilization in Beijing has 40 years history.In order to grasp the development potential of geothermal resources in Beijing,this paper carries out the potential assessment of geothermal resources based on the characteristics analysis of tectonic,the types of geothermal resources and the distribution of geotemperature.Based on the geothermal energy extraction coefficient,the exploitation of geothermal water and the water level deceleration,regionalization of the geothermal resources potential in Beijing is constructed.The geothermal fields are divided into 29 evaluation units and are divided into six zones including serious overdraft area,overdraft area,balance area,low potential area,higher potential area,and highest potential area.
