Abstract: 75 exotic weed species belonging to 55 genera, 30 families are identified and recorded in Hangzhou through investigation and related literatures. The composition, origin area, invasive routes and habitat characteristics are discussed in this paper. The results show that: Compositae, Amaranthaceae, Euphorbiaceae, Leguminosae and Convolulaceae are the five main families, comprising about 55 percent of the exotic weeds in Hangzhou; Exotic weeds originating from America are easier to invade and take more harm to Hangzhou; Uncovered habitats such as wasteland trend to be invaded and settled more easily than others. And some effective management strategies are proposed.

Key words: Hangzhou, exotic weeds, biological invasion
