| 摘 要： | 对闽西邱家山长苞铁杉天然林、常绿阔叶林和杉木人工林的林冠层、林下植被层和凋落物层的持水量、土壤的蓄水能力和渗透性能进行研究 ,结果表明 :长苞铁杉天然林地上部分持水量与常绿阔叶林接近 ,分别为 2 5 8 4 2 6t·hm-2 和 2 77 2 4 2t·hm-2 ;林地土壤的稳渗值亦相近 ,分别为 6 6 8mm·min-1和 6 91mm·min-1,分别是杉木人工林土壤的 1 8倍和 1 9倍。说明了长苞铁杉天然林具有良好的水源涵养功能

| Abstract: | The results showed that the water-holding content of above-ground protion of Tsuga longibracteata nature forest was close with that of T.longibracteata evergreen broad-leaved forest,they were 258.426 T/ha and 277.242 T/hm~2,the steady permeation values of forest-land soil were also close,6.68 mm/min and 6.91 mm/min,respectively,which were 1.8 times and 1.9 times as large as that of Cunninghamia lanceolata plantation soil,respectively.It showed that T.longibracteata nature forest owned fine water conservation function. |
