【摘要】 松材线虫(Busaphelenchus xylophilus)从入侵、定居、适应到蔓延、扩散和危害,是一个多点、多次、长期、复杂的生态过程,其随机性、突发性和长期性的发生特点决定了防控松材线虫病是一项复杂性、长期性和艰巨性的任务,目前常规的防控技术显然存在局限性。从森林演替的角度来看,松材线虫病是松林的生态灾害,在森林生态系统范畴内探讨松材线虫等林业有害生物的发生和防控问题,十分必要。本论文在深入分析松材线虫病的发生特点、流行规律,以及监测和防控难点的基础上,阐述了调控树种结构防控松材线虫病等林业有害生物的理论、实践和技术,为持续控制松材线虫病,实现森林避灾、御灾、防灾、减灾目标,促进马尾松林生态系统良性演替提供技术支撑。更多还原

【Abstract】 The occurrence of Bursaphelenchus xylophilus is a multisite, frequent, long-term and complex ecological process, which run through its invasion, settlement, adaptation and spreading. The occurrence characteristics make the control of B. xylophilus a complex, long-term and arduous task. There are obvious limitations in the current control methods. B. xylophilus is an ecological disaster of pine forests on the perspective of forest succession, thus it is very necessary to discuss the occurrence and control of forest pests such as B. xylophilus in the forest ecosystem category. Based on in-depth analysis of occurrence characteristics, epidemic regularity, monitoring and control difficulties of B. xylophilus, the theory, practice and technology of controlling forest pests by regulating tree structure were set out in this article. These would provide technical support for continuous control of B. xylophilus, for accomplishing the goal of disaster avoidance, disaster prevention and disaster reduction, and for promoting the benign succession of Pinus massoniana forest ecosystem.更多还原
