近年来,随着国家加大对林业的管理力度,我国森林面积逐年增长。但是,林业有害生物现象也日趋严重,并且存在持续蔓延的趋势,对森林持续有效的发展具有重大威胁。为保证我国林业的良好发展,必须要加强对林业有害生物的防治,加强对相关技术的研究。基于此,阐述林业有害生物产生的原因,并试分析了防治技术。 In recent years, with the state increasing the management of forestry, China’s forest area increased year by year. However, the phenomenon of forestry pests is also aggravating and there is a trend of continuous spread, posing a significant threat to the sustained and effective development of forests. In order to ensure the sound development of forestry in China, we must strengthen the prevention and control of forestry pests and strengthen the research on related technologies. Based on this, the causes of forestry pests were explained, and the prevention and treatment techniques were analyzed.
