松材线虫入侵在生态系统水平上的研究现状与展望

Present Conditions and Prospects of Study on Bursaphelenchus xylophilus Invading Ecosystems

松材线虫是由外来入侵种松材线虫做病原、天牛做媒介,引起的一种林木病害,对我国的松林生态系统造成了严重的破坏,也给我国的经济造成了巨大的损失。对生物入侵种松材线虫国内外的研究现状进行综述,指出了松材线虫病研究集中的几个方面,进一步指出松材线虫入侵在生态系统水平上的研究,提出了在生态系统水平的研究方向。

Bursaphelenchus xylophilus disease is a sort of disease of pine tree caused by the invading Bursaphelenchus xylophilus pathogeny, using Monochamus alternatus as the medium, which does great harm to the ecosystems of pine forest. Through the study on Bursaphelenchus xylophilus, we can propose prevention to defend the ecosystem. This paper summarizes present study situation of Bursaphelenchus xylophilus at home and abroad, and some major aspects of study. The damage of Bursaphelenchus xylophilus on ecosystems is pointed out further. At last, research objective of ecosystems in the future is presented.
