摘　　要：沿江地区是安徽省中低温地热的主要分布区。地热分布与构造关系密切,热储多是基岩裂隙、岩溶地层,热水主要接受大气降水补给。区内地温梯度为1.73～4.11℃/100m,热流值的变化范围为44～78.7mW/m2。经计算区内的地热资源丰富。近年来沿江找热经过努力有所突破。The area along the Yangtze River is the main host of meddle-low-temperature geotherm in Anhui. Geothermal distribution is substantially related to structure. Thermal reservoirs are mostly the bedrock rifts and karst strata, and the thermal water is supplemented mainly by precipitation. The geotemperature gradient is 1.73° - 4.11 ℃/100m and thermal flow varies in 44 - 78.7mW/m^2 in the area. Calculation shows rich geothermal resources in the area. During recent years, there have been some breakthroughs in prospectiong of geotherm along the Yangtze River.
