新技术在林业有害生物防治中的应用

Application of new technology in pest control of forestry

森林作为生态环境的主要组成部分,能够调节与改善空气质量,维持生态平衡,对涵养水源、防风固土、防洪减灾以及防止滑坡、泥石流具有重要意义。在国家政策的大力支持下,全国各地以已有林地资源为依据,以改善生态环境质量为契机,不断加快生态建设的脚步,促进生态环境的稳步发展。但是,由于国际贸易的不断发展以及不恰当的引入外来物种,导致外来物种不断扩大,因为没有天敌,有的物种泛滥成灾。在这种情况下,引进何种技术来防治林业有害生物,对提高林木的成活率具有重要的意义。

As a major component of the ecological environment,forests can regulate and improve air quality,maintain ecological balance,and have important implications for water conservation,wind and soil conservation,flood control and disaster prevention,and prevention of landslides and debris flows. With the strong support of national policies,all parts of the country use the existing woodland resources as a basis,taking the improvement of the quality of the ecological environment as an opportunity to constantly accelerate the pace of ecological construction and promote the steady development of ecological environment. However,due to the continuous development of international trade and the improper introduction of alien species,alien species have been continuously expanded because there are no natural enemies and some species are flooded. Under such circumstances,what kind of technology is introduced to prevent and control forest pests is of great significance to improving the survival rate of forest trees.
