| 摘 要： | 文章对樟树、黧蒴、假苹婆、米老排和高山榕等5种林分改造树种凋落物储量及持水特性进行了研究。结果表明,樟树、黧蒴、假苹婆、米老排和高山榕凋落物鲜重分别为7.63,6.90,6.38,13.95和7.55 t/hm^2。各树种凋落物干重为米老排〉樟树〉高山榕〉黧蒴〉假苹婆。5种树种中米老排凋落物的最大持水量和最大持水率最大,分别达23.81 t/hm^2和338.89%;高山榕最小,分别仅为11.35 t/hm^2和167.11%。各树种凋落物的最大拦蓄量与有效拦蓄量变化规律基本一致,顺序都是米老排〉黧蒴〉假苹婆〉樟树〉高山榕。在不同浸泡时间段,各树种凋落物持水量均呈现米老排〉黧蒴〉假苹婆〉樟树〉高山榕。0.5 h内,凋落物吸水速率为米老排〉假苹婆〉黧蒴〉樟树〉高山榕。

| 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 7.63,6.90,6.38,13.95 and 7.55 t/hm^2,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/hm^2 and 338.89%） among the five tree species,F.altissima were least（11.35 t/hm^2 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 0.5 h was M.laosensis 〉S.lanceolata〉 C.fissa 〉C.camphora F.altissima. |
