| 摘 要： | 通过对四川沐川县天然林、人工林（水杉林）枯落物蓄积量调查分析和持水特性的研究结果表明：枯落物蓄积量为天然林＞人工林（25.7 t·hm-2＞ 18.1 t·hm-2）,最大持水量为天然林＞人工林（75.0 t·hm-2 ＞47.0 t·hm-2）,最大持水率为天然林＞人工林,各时段吸水量、吸水速率表现为天然林＞人工林,有效拦蓄量表现为天然林＞人工林（28.6 t·hm-2＞ 17.0 t·hm-2）.总体分析可以看出,天然林落物层保水功能相对要比人工林好.

| Abstract: | Investigations and analysis were made of the reserves of litter and its water retention character- istics in natural forest and artificial forest in Muehuan county, Sichuan. The results showed that litter re- serves were natural forest 〉 artificial forest（25.7 t · hm-2 〉 18. 1 t ·hm-2） ;Maximum water retention capacity was natural forest 〉 artificial forest（75.0 t· hm-2 〉 47.0 t· hm-2） ;Maximum water retention ratio, water absorption and water absorption speed were natural forest 〉 artificial forest; Effective retaining content was natural forest 〉 artificial forest（28.6 t · hm-2 〉 17.0 t · hm-2）. In general, water conserving function of natural forest was better than that of artificial pinust abulaeformis forest. |
