近年来,国家对生态环境建设十分重视,从政策上、资金上给予大力扶持,全国新造林面积大幅度增加。同时,由于森林病虫害预防措施不到位,人工纯林、经济林面积所占比重不断提高,给森林病虫害的发生埋下了隐患。要防止森林病虫害的大发生,按照“预防为主,综合治理”的方针,森林病虫害的防治工作应从造林工作的各个环节抓起。
In recent years, the state attaches great importance to the construction of the ecological environment and has given strong support from the policy and financial levels. The area of new afforestation in the country has risen sharply. At the same time, as the precautionary measures for forest pests and diseases are not in place, the proportion of artificial pure forests and economic forest areas has been continuously raised, laying a hidden danger to the occurrence of forest pests and diseases. To prevent the occurrence of forest pests and diseases, in accordance with the principle of “prevention first, comprehensive management”, prevention and control of forest pests and diseases should start from all aspects of afforestation work.
