摘　　要：根据近年勘探研究成果，结合部分已开发利用地热资源情况，对郑州市地热资源的赋存规律和成因进行讨论。郑州市地热资源分南、北两区，南区为三李—郭小寨浅源热异常区，地热埋藏较浅（６０～１８０ｍ），温度较高（４０～４７℃），成因属隆起断裂型；北区为郑州市城区深源热异常区，地热埋藏较深（８００～１３００ｍ及以下），温度相对较低（３８～４５℃），成因属沉降盆地—构造断裂型。文中还对郑州市地热田的储、盖、通、源条件及其形成特征进行了论述。Based on exploration and research in recent years and on the state of exploitation and utilization of geothermal resources, the hosted regularities and genesis of geothermal resources in Zhengzhou City has systematically studied in detail in this paper. The geothermal resources distribute in the south and the north regions of Zhengzhou: the south region is called the Sanli Guoxiaozhai shallow anomalous heat region, its buried depth is more shallow (60～180m),but its water temperature is higher (40～47℃), its genesis belongs to the lifted-fracture type. The north region is deep-rooted anomalous heat region of the city proper of Zhengzhou. Its buried depth is deeper (800～1300m or more),but the water temperature is relatively low (38～45℃) and is genesis belongs to the depressed basin tectonic fracture type. In addition, some main conditions and the formation feature about the geothermal field in Zhengzhou have been discussed in this article.
