摘要:针对陕西、甘肃、内蒙古、青海、宁夏和新疆西北6省(区)目前的森林现状,分析了两北部地区森林生物灾害的发生特点:主要是(1)森林病虫鼠害严重,尤其是害鼠种类多、分布范围广,危害严重。(2)钻蛀性害虫发生隐蔽,控制困难。(3)干旱和生物多样性贫乏使食叶害虫的暴发周期缩短。预测未来10年森林生物灾害的发展趋势为:(1)总体发生趋势平稳;(2)病虫种类将明显增加;(3)森林鼠害面积明显增加,危害程度在一定时期内会更加严重;(4)杨树蛀干害虫的危害仍然严重。进而提出了可持续控灾的5点策略。
Based on the present forest condition in Shanxi, Gansu, Inner Mongolia, Qinghai, Ningxia and Xinjiang (6 provinces and autonomous regions) , the paper analyzed the occurrence of forest disaster caused by bioagent (bio-disaster) in these regions, the characteristics of which are as follows; (1) Forest diseases of insect and rodent pests are very serious with many species of rodent, which distributed widely and caused very serious damage in these regions; (2) It is difficult to find and control tree borers; (3) The occurrence interval of defoliators is shortened by drought and there is a lack of biodiversity in these regions. The occurrence trend of forest bio-disaster in the next 10 years is predicted; (1) The total occurrence trend will be steady; (2) The number of pest species will obviously increase; (3) The damaged area caused by forest rodents will obviously increase, and the damage will be more serious; (4) Damage caused by tree borers will be still serious. The five sustainable control strategics for forest bio-disaster was put forward in the paper.
