Investigation and Study on the Alien Invasive Plants along Nan-You Expressway of Guangxi
摘要
Abstract
Based on the investigation about the present situation of the cultivated plants along Nan-You expressway, the alien invasive plants were investigated and analyzed. The results showed that there were 46 species of alien invasive plants belonging to 36 genera and 18 families along Nan-You expressway, accounting for 40.4 % and 12.1%, respectively in Guangxi province and China. The largest family was Compositae which involved 10 species and most of the plants （23 species ） came from Trop- ical America. There were 30 species of herb amounting for the largest plant traits. Among them , Eu- patorium odoratum caused very serious negative consequences, 6 species （Ageratum conyzoides, Bidens pilosa , Bidens pilosa var. radiata , Parthenium hysterophorus , Wedelia trilobata and Ipomoea cairica ） resulted in significantly negative effects. There were 29 plants which intruded by natural propagation which was the major way to propagate. However, the Parthenium hysterophorus which was intentional cultivated was also bringing serious harm.关键词
