Banchengzi catchment was selected as the study area,and Pinus tabulaeformis was selected to investigate the stock volume and water-holding capacity of litter layers.The results showed that:(1) the stock volume of Pinus tabulaeformis litters was 21.86t/hm2,of which the volume of undecomposed litters was 7.04t/hm2 and accounted for 32.20%,the volume of half decomposition was 14.82t/hm2 and accounted for 67.80%,and indicated that the volume of undecomposed litters was larger than undecomposed litters;(2) litters volume was significant with leaf area index(LAI),and increased with larger LAI;(3) the water holding of litters showed a process of “rapid absorption-slow absorption-gradual saturation”,the absorption rate decreased with immersion time,and showed a power function relationship(V=ktn).The research results can provide references for forest management and water holding monitoring process in catchments.
