| 摘 要： | 对广西横县镇龙林场不同年龄尾巨桉（Eucalyptus urophylla×E．grandls）人工林凋落物层和土壤层的水源涵养能力进行比较研究。结果表明：随着尾巨桉林龄增大，地表凋落物总量也逐渐增大，5年生林分地表凋落物量最高；凋落物层最大持水量与凋落物量呈显著正相关（P〈0．05）。表层土壤非毛管孔隙度和非毛管孔隙... |

| Abstract: | The water-conservation capabilities of litter layer and soil layer in Eucalyptus urophylla ×E. grandis plantations at different ages were compared in Zhenlong Forest Farm, Guangxi province. The results showed that litter accumulation and its maximum water-conservation capacity increased with stand age and reached its peak in 5 yrs old plantation. There were positive relationships between litter accumulation and its maximum water-conservation capacity （ P〈0.05） . Noncapillary porosity and the ratios of noncapillary porosity and capillary porosity gradually decreased with stand age. The water-conservation capacity of 0 - 60 cm soil and the integrated water-conservation capacity tended to decrease with the augmentation of stand age. |
