[Objective] To provide theoretical basis for ecological environment construction and the work of soil and water conservation, water-holding capacities of litters were measured in different types of ecological landscape forest in Daxing Distrct, Beijing City.[Methods] Litters in 10 types of forest were taken as the study objects, the water-holding capacities were explored by indoor soaking method.[Results] The litter storages of the 10 forests ranged from 2.37 to 5.33 t/hm², ranked as:Populus tomentosa > Pinus tabulaeformis > Ailanthus altissima > Robinia pseucdoacacia > Sophora japonica > Ginkgo biloba > Ulmus pumila > Acer truncatum > Salix matsudana > Prunus cerasiferacv. The maximum water-holding capacities and rates ranged from 5.56 t/hm² to 24.92 t/hm², and from 208.64% to 481.62%; and the maximum interception amount and the effective interception amount ranged from 5.37 to 24.24 t/hm² and from 4.54 to 20.51 t/hm², respectively. Water-holding capacities of all types of litters changed logarithmically with soaking time as independent variable; whereas water absorption rates all followed power function.[Conclusion] The comprehensive analysis of water-holding capacities of the 10 forests indicated that Populus forest has a higher water-holding capacity and is more beneficial for water conversation.
