%X With simulation test,this paper studied the effects of water level on the rhizomatic germination and growth of Calamagrostis angustifolia and Carex lasiocarpa,the two typical wetland plants in Sanjiang Plain.The results showed that these two plants had different responses to water level.The population density,mean height,and maximum height of C.angustifolia reached the peak at 0 cm water level;while the mean and maximum height of C.lasiocarpa increased,but its population density decreased with increasing water level.At the early stage of germination,definite duration without inundation promoted the rhizomatic germination of these two plants,while continuous inundation constrained it.During growth period,excess inundation limited the growth of C.angustifolia,but C.lasiocarpa grew better under deeper water.Drought constrained the growth of C.angustifolia and C.lasiocarpa,and possibly,changed their life history.
