Surface heat fow q〓and heat generation A〓of Yunnan area are regressed, the linear regression correlation is: q〓=55.36+9.17A〓,wth regresion coefficient: r=0.7345 and reduced heat flow q〓=55.36mW/m〓. However, the q〓-A〓relationship can not explain the heat flow pattern of the area because this is a convergence area of several terrains with different geological structure and evolution history.
