Among them, the outcrop area is 900,000km2, buried area is more than 2,500,000km2 . 华北盆地北部岩溶热储 karstic geothermal reservoirs in north China Typical geothermal reservoirs: Beijing, Tianjin, Baoding, North Jiangsu 类比法估算碳酸盐岩热储资源量 （可回收热量） 据类比法估算的全国碳酸盐岩热储地热资源量（考虑潜山面积比例） The estimated values of carbonate karstic geothermal resources according to the analogy method (considering buried hill area rate)
