Abstract：In this paper more attentions are paid to the litters in different forest types and precipitation features,thus litters interception have been observed by the simulation method in site in different types of dark coniferous forest communities at four successive stages.And the max absorption intensity of litters in different forest types had been observed by immersion in water.Results show that rainfall of litter interception in different forest types is linearly correlated to rainfall outside of stands.There is typical power function relation between litter interception and throughfall.The water holding ability of litters has relation to amount and composition of litters,while its decomposition degree is positively related to stand age.And the litter interception capability is influenced by original wetness degree of ground cover.
