| 摘 要： | 通过室内浸泡法对川西低山区天然林及其人工更新形成的1～3年生巨桉(Eucalyptus grandis)林林下枯落物持水性进行了研究.结果表明,枯落物蓄积量由高到低为天然林、I3、I2、I 1；枯落物最大持水量、最大拦蓄量、有效拦蓄量由高到低均为天然林、I3、I 2、I 1.天然林转变为巨桉林后林下枯落物持水性随着林分年龄的增加而增强,对维持原有林地枯落物层持水功能具有较好的作用.

| Abstract: | The litter water-holding characteristics of natural forest and different ages of artificial Eucalyptus grandis plantation were determined by indoor immersion method.The result showed that the litter storage,litter max water-holding capacity,max interception and modified interception,all ranked from high to low as natural forest,3-year-old E.grandis,2-year-old E.grandis,1-year-old E.grandis.The litter water-holding capacity was increased with the tree age after natural forest converted to E.grandis plantation,which was important to maintain the litter layer water-holding capacity of original forest. |
