Abstract: Learning the vertical distribution of the radioactive heat production of rocks is the foundation of studying the crustal thermal structure.On the basis of seismic data and relationship between the seismic velocities and heat production we have estimated the vertical distribution of the heat production for the crust of Yunnan Province.The results indicate that the general heat production is 0.8～2.1μW/m³ for the upper crust,0.4～1.2μW/m³ for the middle crust,and 0.11～0.55μW/m³ for the lower crust.

摘要： 研究地壳岩石放射性生热率的垂向分布,是研究深部热结构的基础。根据深部地震测深资料,利用地震波速与生热率之间的关系,估计了云南地壳生热率的垂向分布。全区上地壳生热率一般为0.8～2.1μW/m³,中地壳为0.4～1.2μW/m³,下地壳为0.11～0.55μW/m³.
