The water-holding characteristics of litter were analyzed in the paper,including the total storage capacity,water holding capacity,water rate and water absorption rate for Sabina saltuaria forest,Larix griffithiana forest,Picea likiangensis var.linzhiensis forest,Pinus densata forest,Abies georgei var.smithii forest by the field observation and indoor extraction.The results showed that the total storage capacity of litter ranged from 8.48 t/ hm2 to 19.2 t/hm2,and the order was P.densata forest>A.georgei var.smithii forest>P.likiangensis var.linzhiensis forest>S.saltuaria forest>L.griffithiana forest.The maximum water holding capacity of litter presents A.georgei var.smithii forest>P.densata forest>L.griffithiana forest>P.likiangensis var.linzhiensis forest>S.saltuaria forest.The maximum proportional water holding capacity of litter was Larix griffithiana forest>Abies georgei var.smithii forest>P.likiangensis var.linzhiensis forest>P.densata forest>S.saltuaria forest.The water holding capacity and the proportional water holding capacity of litter increased logarithmically with the soaking time.The water absorption rate of litter was L.griffithiana forest>A.georgei var.smithii forest>P.likiangensis var.linzhiensis forest>P.densata forest>S.saltuaria forest.The water absorption rate with soaking time was an obvious power function.The research results provided a theoretical basis for sustainable utilization and resources evaluation of water conservation forest in the Sejila Mount.
