阐述了云南大地热流分布特征，并从地壳结构入手探讨了地壳、上地幔的生热率垂向分布，进而研究了云南的深部热流结构．研究结果表明，垂向上，上地壳所产生的热流量最大，中地壳次之，下地壳最小；横向上，各构造单元深部热流结构差别较大，全区地幔热流变化范围是１９～５７ｍＷ／ｍ２．
The distribution characteristics of the geothermal heat flux in Yunnan are expounded, and the vertical distribution of the heat production rate in the crust and the upper mantle is discussed from the crustal structure. Then the deep heat flow structure in Yunnan is studied. The results show that the upper and lower crusts generate the largest heat flux in the vertical direction, followed by the middle crust, and the lower crust has the smallest crust. In the horizontal direction, the structure of the heat flux in each structural unit is quite different. The range of the heat flux in the whole area is 19-57 mW / m2 .
