Abstract:

According to the field investigation and literature analyzing,there are 56 alien weeds belonging to 44 genera,21 families are identified and recorded in West-Lake scenic spot. The species composition, source,and the distribution characteristics are discussed in this paper. The results show that:(1)Compositae,Amaranthaceae,Leguminosae are the three main families;(2)most of the alien weeds originated from North America;(3)uncovered habitats such as wasteland trend to be invaded and settled more easily than others;(4)their occurrences have seasonal differences;(5)species and distribution have dynamic alteration. The changes of alien weeds in 20-30 years were also discussed.
