紫茎泽兰Eupatorium adenophorum Spreng.在中国入侵分布预测

Predicting the Potential Invasive Distribution for Eupatorium adenophorum Spreng. in China

原产于墨西哥的紫茎泽兰 Eupatorium adenophorum Spreng.作为一个有害的外来物种在印度、新西兰和澳大利亚生长已有很长时间。在中国 ,尤其是在南方和西南地区其蔓延速度之快 ,带来了不可忽视的经济和社会后果。我们采用了生态位模拟新方法来预测紫茎泽兰可能入侵的范围。据此 ,预测的潜在分布区包括该植物在中国境内已分布的省份及未来华中。

Originating in Mexico, Eupatorium adenophorum Spreng., is a noxious weed long present as a non native species in India, New Zealand, and Australia. In China, it is spreading rapidly, particularly in the southern and southwestern parts of the country, with serious economic and social consequences. A new method, ecological niche modeling, was applied for predicting its potential geographic range of invasion. Predicted potential distributional areas included the Chinese provinces where the plant is known to occur, as well as additional areas in central and eastern China that appear susceptible to further spread of this species.
