【Abstract】 The present paper aims to introduce the author’s field research on the bio-invasion situation in Jilin province and the corresponding countermeasures to be taken to effectively protect and prevent from the bio-invasion. Bio-invasion is very common in the world, which leads to the intrusion of exoticspecies into human-bodies, products and substances in nature. Through our field research in Tonghua, Jilin, we have collected abundant data and information on the invasion species and their related pernicious characteristics to the local economy and human lives in the province. So far we have collected and analyzed seven exoticspecies (Lissorhoptrus oryzophilus, Matsucoccrs matsumurae, Mallambyx raddei, Acanthoscelides obtectus, Liriomyza sativae, Dorhistroma pimi Hulbary, Ambrosia trifida L.), which are highly detrimental in nature and widespread in the province. They spread quickly in different ways, but mostly invade into human body and substances in an unconscious and invisible way. Our research has also discovered that the most likely places to be invaded are the artificial communities with simple bio-structure. It is also found that these places to be invaded are mostly distributed in the eastern parts of the province, where the climate is mild and the biodiversity is more abundant. The economic loss caused by such exoticspecies has been great not only to the natural environment, but also to the society and economy. Facing the situation, we have prepared the effective countermeasures in hoping to prevent and control the invasion of such exoticspecies. It is also expected to launch cooperative research projects to study effective ways on how to restore the healthy ecological environment system and publish research achievements in this way with the advanced countries so as to reduce the detrimental effect caused by the invasion of such exoticspecies.更多还原
