Abstract: Exotic invasive species have long been known to bring about serious damages to ecosystem, which has imposed great threats to national eco-safety . Since the late 1990s, ecological impacts caused by Mikania micrantha H . B . K .,
an invasive plant species, have become the focus of different walks of society . No existing literature on M. micrantha , however , relates anything concerning its distribution in Yunnan Province . Based on field investigations and taxonomic
study on the specimen collected in Kunming Institute of Botany, the authers identified two species of Mikania Wild in Yunnan , namely M. cordata and M. micrantha . The present research also depicts the impacts of M. micrantha in Dehong, a pefecture in Southwestern Yunnan . Considering the biological features of the species , the author predicts there are possibilities of spreading of the species in Dehong prefecture , and possibly diffusing over other areas with identical climate patterns as Dehong . In the wake of this , it is highly advised that government departments and relative research institutes
pay great attention to the problem and take effective measures to deal with situation .
