Abstract:This paper studied on the litter amount,natural water content and water holding characteristics of litter layer under the natural evergreen broadleaved forest and three artificial plantations,Sassafras tzumu,Cryptomeria fortunei and Metasequoia glyptostroboides forests,which formed by natural evergreen broadleaved forest artificial regeneration.The results showed that the amount of litter layer is natural evergreen broadleaved forest(25.68 t/hm~2)>Metasequoia glyptostroboides forest(18.14 t/hm~2)>Sassafras tzumu forest(9.95 t/hm~2)>Cryptomeria fortunei forest(1.13 t/hm~2).The natural water content of whole litter layer in natural evergreen broadleaved forest is 3.18,41.33,1.53 times of that in Sassafras tzumu,Cryptomeria fortunei and Metasequoia glyptostroboides forests,respectively.During the process of water holding of litter layer,the water holding capacity and absorption speed of the first 2 h were superior to the rest of time.The equation between the water holing capacity of the litter layer and the immerse time is Q=alnt b,the equation between the water absorption speed of the litter layer and the immerse time is V=kt~n.The maximum water holding capacity,the maximum interception and the modified interception of litter layer are natural evergreen broadleaved forest>Metasequoia glyptostroboides forest>Sassafras tzumu forest>Cryptomeria fortunei forest.Therefore,protecting natural evergreen broadleaved forest and choose appropriate afforestation tree for artificial regeneration of natural evergreen broadleaved forest were important for enhancing the eco-hydrological benefits of forest litter layer.
