摘　　要：干热岩型地热资源作为一种清洁可再生能源,以其分布的普遍性和高热储温度而更具开发潜力与前景。按照成因机制和赋存条件可分为高放射性产热型、沉积盆地型、近代火山型和强烈构造活动带型四种类型。唐秦地区乐亭—昌黎一带隶属于我国所划分的干热岩开发有利靶区——华北(渤海湾盆地),重点论述了区域地热地质背景、地球物理等特征,综合分析认为乐亭—昌黎一带具有较好的寻求沉积盆地型干热岩资源的潜力。As a clean and reproducible energy, hot dry rock resources have more exploitative potential and pros- pect due to its universality of the distribution and high heat storage temperature. Based on the genetic mechanism and occurrence conditions, the hot dry rock resources are divided into four types： the high radioactive heat produc- tion type, the sedimentary basin type, the modern volcano type and the intraplate active tectonic zone type. The belt of Laoting-Changli in Tang-Qin area belongs to one of the hot dry rock development favorable target areas divided by our country, namely： North China （Bohai bay basin）, this paper mainly discusses the regional geothermal geological background, and the geophysical characteristics, and based on the comprehensive analysis, the Laoting-Changli area has good potential for the hot dry rock of sedimentary basin type prospecting.
