The aim of this paper is to investigate the characteristics of seed banks in six land use types of urban wetland in Hangzhou Xixi. The results show that the seed bank density of abandoned farmland and farmland are more than the others. The seed banks density of the uprightness in abandoned farmland, pond bank I, II and bamboo non-timber forest are downtrend, which is different from the pattern of low-high-low in farmland, and there is no difference among the density of three lays in man-made landscape area. There are 35 families and 102 species totally according to six different land use types of urban wetland in Hangzhou Xixi. A part of its seed bank types obtain the seeds of shrub, which the annual and perennial seeds use the interval of early spring to germinate as the same as farmland type. Farmland type also owns another small part of the seed banks which germinate in Autumn. The seed banks type of bamboo non-timber forest and pond bank are the herbage and shrub type germinating under the condition of drought and interference with the contribution of permanent seed banks.
