介绍了欧美国家在森林生物灾害预警方面的研究成果和所采取的措施。美国的森林病虫害预警系统是由一些合作机构和子系统组成的一个网络,由潜在威胁的鉴定、真实威胁的检测、评价影响和响应4个关键步骤组成。加拿大食品检验局建立了基于互联网的植物健康预警系统,在森林病虫害预测方面,一个通用的软件包BioSIM已获得加拿大林务局的认可。欧洲和地中海植物保护组织针对外来有害生物通过贸易途径侵入方面建立了数据库EUROPHYT,各成员国还有各具特色的预警措施。
The research results and measures adopted by the European and American countries in early warning of forest biological disasters are introduced. The United States forest pest warning system is a network of cooperating agencies and subsystems composed of four key steps: identification of potential threats, detection of actual threats, assessment of impact and response. The Canadian Food Inspection Agency has established an Internet-based plant health warning system. BioSIM, a common software package for forest pest prediction, has been approved by the Canadian Forest Service. Europe and the Mediterranean Plant Protection Organization has set up the database EUROPHYT on the invasion of exotic pests through trade routes. Member States also have their own special precautionary measures.
