摘要

Forest disasters mainly refer to insect pest, rodent damage, forest fire and frost damage. Snow damage, windstorm, drought, flooding, landslide, mud-rock flow, environmental pollution and so on all cause damages to forest resources. The greatest damage is caused by forest disease,insect pests, rodents and fire. With the large-scale exploiture and serious denudation of primitive secondary forests, the appearance of artificial pure forests on a massive scale and the deterioration of the national forest eco-environment, forest damages caused by diseases, insect pests and rats have been on the increase, with the afflicted area doubling every ten years on the average for the period 1949～1989.
