[Objective] Assessing water storage capacity of three types of wetland in Zoige wetland in order to provide the scientific basis for the assessment of the hydrological function value of wetland ecosystem.[Methods] We measured the physical properties and maximum retention capacity, and evaluated soil water storage capacity of three types of the Zoige alpine wetland.[Results] (1) Within a depth of 0-60 cm, the soil bulk density of three types of wetland increased with soil depth increase, but at the depth of 80-100 cm in marshes, 60-80 cm in swamp meadow and floodplain wetland the soil bulk density decreased; (2) Within the range of 0-100 cm, the soil capillary porosity of marsh meadow shows a decreasing trend with depth, but no apparent trend in the other two wetland types; (3) Within the range of 0-100 cm, the mean value of soil bulk density in three types of wetland showed an order as marshes(0.46 g/cm³) < swamp meadow(1.08 g/cm³) < floodplain wetland(1.25 g/cm³); The average of the maximum soil water storage capacity was as marshes(239.40 t/hm²) > swamp meadow(171.18 t/hm²) > floodplain wetlands(148.51 t/hm²).[Conclusion] The water storage capacity of the marsh is the best. So when implementing wetland conservation and restoration in Zoige region, the marsh outside the reserve should also be included in the planning.
