Abstract
Pine, China fir and Cypress are sometimes frostbitten in different degrees in cold winters. In onler to explore the freezing resistance of pine, China fir arid Cypress, studies on the freezing resistance of 26 species of pine, China fir and Cypress were made, and the semi-lethal temperature was calculated. The result can be used as a scientific basis for the rational distribution of pine, China fir and Cypress in Yunnan Province.
