森林是国家的宝贵资源,它不仅关系到工农业生产、国防建设和人们的日常生活,而且还具有防风固沙、涵养水源、保持水土、净化空气、调节气候、美化环境等多种生态社会效益。而森林病虫害是森林生态环境恶化,由生物引起的一种严重的自然灾害,是制约我国森林可持续发展的重要因素,已严重威胁到我国森林资源和生态安全。对森林病虫害的综合治理显得尤为重要。
The forest is a precious resource for the country. It not only relates to industrial and agricultural production, national defense construction and people’s daily life, but also has many ecological and social benefits such as windbreak and sand fixation, water conservation, soil and water conservation, air purification, climate regulation and beautification of the environment. However, forest pests and diseases are a serious natural disaster caused by the deterioration of forest ecological environment and an important factor restricting the sustainable development of our country’s forests. They have seriously threatened forest resources and ecological security in our country. Integrated management of forest pests and diseases is particularly important.
