摘要
根据大地热流和岩石圈结构资料，探讨了云南岩石圈的地温分布。研究结果表明，全区存在３种地热类型：高地温型莫霍面温度＞９６０℃，地壳地温梯度＞２℃／１００ｍ；低地温型莫霍面温度＜７００℃，地壳地温梯度＜１．５℃／１００ｍ；中等地温型莫霍面温度介于前二者之间，地壳地温梯度为１．５～２．０℃／１００ｍ。
According to the data of the heat flow and lithospheric structure, and the correlative formula between the heat production A and the seismic velocity V P, the distribution of the lithospheric geotemperature in Yunnan has been studied. Three geothermal types exist in whole Yunnan region: high geotemperature type with the Moho temperature >960℃ and the crustal geothermal gradient >2℃/100m, low geotemperature one with the Moho temperature <700℃ and the crustal geothermal gradient <1.5℃/100m, and middle geotmeperature one with the Moho temperature lying between the former two types and the crustal geothermal gradient 1.5 ～ 2.0℃/100m.
