摘　　要：滇东南薄竹山地区温泉出露5处,分别分布于薄竹山花岗岩体的南西、北东两侧,均为上升泉,其热水化学类型均为HCO_3-Na^+型;温泉补给来源主要为大气降水,补给高度在海拔2 000m以上;呈带状热储结构,热储温度以邻区类比为70~110℃;估算热水循环深度2 580~2 977m.区域内北西向张性断裂及发育的岩溶通道起主要导水作用,区内发育的构造裂隙网起导热作用.该区温泉成因模式为大气降水补给的断裂深循环型地热系统.There are five hot springs,which is distributed in the south west and north east side of granite body in Bozhushan area in southeast of Yunnan Province. All of them are ascending springs and the heat-hydro chemical type is HCO3--Na＋. The source of replenishment is atmos- pheric precipitation,and its replenishment height is above an altitude of 2 000 m. The reservoir structure is banded,and its temperature is 70--110℃ according to analogy with adjacent regions. Estimated heat-water circulation depth is 2 580--2 977 m. Main water channels are the north-west faults and karst channel of this area,furthermore the structural fissures network plays a role of conducting heat. The genetic model of springs in this area is fracture deep circular geothermal system recharged from atmospheric precipitation.
