面向2l世纪的森林防灾减灾

Forest Protection Towards the 21^(st) Century

本文回顾了森林防灾减灾的历史,认为我国森林防灾减灾在世纪之交面临的危机是:历史性的重大有害生物没有得到有效控制,一些次要性有害生物正在逐步演化成主要威胁,检疫性病虫害构成威胁,生态环境整体恶化为诱因的生态性病虫害爆发成灾,非生物性灾害加剧,寄主主导性病害是我国西部开发战略转移实施的潜在威胁.提出了面向21世纪我国森林防灾减灾的策略,认为2l世纪初重大研究课题是:森林有害生物生态控制和基因控制的理论及技术,并在基础研究和技术研究两个层次上提出了研究的总体目标和基本内容.

:This paper reviews the history of forest protection. Its progress is a passive procedure in the past half century. Lots of serious disasters will become to be the crisis of forest development at the turn of the centuries. Historical important pests were still not effectively controlled. Some secondary pests are now gradual to be main menace. Quarantining pests are becoming menace. With the deterioration of the ecological environment, ecological diseases break out into disasters. Non-biological disasters aggravated. Host leading diseases will be the potential threat to the development of national west. Strategies to solve these important problems are proposed for forest protection towards the 21st century. The theories and technology of ecological controlling and gene controlling are most important research subjects at the beginning of next century because of the goal of the sustainable forest pest management. The total goal and content of the research of forest protection is advanced including foundamental and technology research.
