近年来,我省森林病害越来越重,究其原因,主要是由于天然林的森林生态系统不断恶化,而人工林的森林生态系统又未及时恢复之故。在贯彻“预防为主、综合防治”的方针时,应以生态学、病理学、经济学观点为基础和以营林措施防治为主,并充分发挥其它措施(包括化学防治)的应有作用,对森林病害的生物防治与人工林生态系控制病害以及新病害及疑难病害的研究工作,必须迅速加强。
In recent years, the growing incidence of forest diseases in our province is mainly due to the deteriorating forest ecosystems of natural forests and the fact that the forest ecosystems of artificial forests have not been restored in time. In carrying out the principle of “prevention first and comprehensive prevention and control”, we should base on the perspectives of ecology, pathology and economics and take the prevention and treatment of silviculture as the main measures, and give full play to the due role of other measures (including chemical prevention and control) , The research on biological control of forest diseases and plantation ecosystem control diseases as well as new diseases and difficult diseases must be promptly strengthened.
