摘要
外来种火炬树引入后所表现出来的优良特性,继而引起现在大面积的栽植,导致火炬树大量的繁殖,这样火炬树可能由一个外来种变为一个生物入侵种,所以我们应当吸取国内外入侵种造成生物灾难的教训,对火炬树大量种植后对生态环境可能产生的不良后果做出生物预警。
With the deepening of our country＇s foreign exchange and cooperation, it is inevitable that we introduce the exotic species because of social needs. But the process could bring some negative influences, for example, biotic invasion. First of all, the paper shows the perfect characteristics of Rhus typhina after it has been introduced. However, in the following years, it has been planted at lots of acres, resulted in the excessive propagation and become a invasive species from a exotic species, So it is time for us to draw a lesson produced by invade species causing the biological disaster both at home and abroad, and we should make biotic warning of bad consequence caused by the Rhus typhina.
