In this paper, the thermal properties of triploid Populus tomentosa clones were studied, and the results showed that there were significant differences in thermal properties among clones. The clonal reproducibility of specific climatic coefficient, thermal conductivity coefficient and thermal conductivity coefficient were 0 59, 0 77 and 0 62, respectively, indicating that the thermal properties of the triploid Populus tomentosa wood have a strong genetic control.Thermal properties and wood density was positively correlated, thermal conductivity and wood density reached a significant significant correlation, wood density and thermal conductivity, guide The correlation coefficients of temperature coefficient and specific heat coefficient were 0 810 0, 0 57 778 and 0 0 938, respectively.
