【摘要】 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．更多还原

【Abstract】 The distribution characteristics of the heat flow in Yunnan have been expounded,the vertical distribution of the heat production for the crust and upper mantle has been discussed from the crustal structure,and the structure of deep heat flow in Yunnan has further been studied.The studies indicate that the heat flow from the upper crust is greatest vertically, greater from the middle crust and smallest from the lower crust,and quite large differences exist laterally in the structure of deep heat flow among various tectonic units.The range of mantle heat flow is from 19 to 57 mW/m 2 in whole Yunnan region.更多还原
