| Abstract: The standing crop and water holding characteristics of Cinnamomun camphora, Castanopsis fissa, Sterculia lanceolata, Mytilaria laosensis and Ficus altissima were studied.The fresh Abstract: The litter standing crop and water holding characteristics of Cinnamomun camphora, Castanopsis fissa, Sterculia lanceolata, Mytilaria laosensis and Ficus altissima were studied. The fresh litter standing crop of C. camphora, C. fissa, S. lanceolata, M. laosensis and F. altissima were 7.63 t/hm2, 6.90 t/hm2, 6.38 t/hm2, 13.95 t/hm2 and 7.55 t/hm2, respectively. The order of dry litter standing crop was M. laosensis > C. camphora > F. altissima > C. fissa > S. lanceolata. The maximum water holding capacity of litter and the most proportional water holding capacity of litter of M. laosensis were largest (23.81 t/hm2 and 338.89 %) among the five tree species, F. altissima were least (11.35 t/hm2 and 167.11 %). The maximum interception amount of litter and the modified interception amount of litter had the same change in different tree species with the order of M. laosensis > C. fissa > S. lanceolata > C. camphora > F. altissima. The order of water holding capacity of litter in the five tree species was M. laosensis > C. fissa > S. lanceolata > C. camphora > F. altissima.The order of water absorption rate of litter in the five tree species within 0.5h was M. laosensis > S. lanceolata > C. fissa > C. camphora > F. altissima. |
