The occurrence of frost damage in forest did not show any decrease trends in the condition of global climate warming, the growing season frost could lead severely damage to the tissues of trees and the whole seedlings. Thus, the frost is becoming one of the major limiting factors for tree growth and regeneration. The occurrence and degree of frost damage to the trees are related to the coupling effect of two factors-the complex environment condition and the cold hardiness of trees, and the former was affected by the large-scale atmospheric circulation and regional microclimate. It will help improve the monitoring and assessment of the frost influences to the forest by coupling the cold hardiness of trees, the spatial the distribution model, which was built based on the factors of radiation and low temperature in a complex topographical condition using 3S technologies, and the probability model. Both physical and biotechnological measures should be taken into account for forest protection under frost impact. The former can balance the energy of near ground surface in forests through establishing protective forest and suitable cutting measures, and later aims at improving the cold hardiness of trees by biotechnological measures. It is therefore, the evaluation for effects of different kinds of frost-prevention measures should combining with the monitoring and evaluation models of frost damage.
