摘要:
分析了不同年龄阶段杉木(Cunninghamia lanceolata)人工林林下枯落物储量及其持水特性，以期为杉木人工林的经营策略及发挥其水土保持功能提供科学依据。结果表明:杉木人工林幼龄阶段、中龄阶段、近熟阶段枯落物储量分别为5.37、15.50、23.31 t·hm-2;同一林分不同层次枯落物最大持水量差异明显;枯落物吸水速度随浸泡时间的延长而降低， 30 min内吸水速度最快，枯落物吸水速度与其浸泡时间相关性极高;随着林龄的增加，单位面积枯落物最大持水能力呈增长趋势，幼龄阶段、中龄阶段、近熟阶段分别为76.93、91.76、108.16 t·hm-2，枯落物最大持水能力相当于水深为6.14、8.04、9.39 mm。
Abstract:
 In order to provide a scientific basis for the Chinese fir plantation business strategy and for the promotion of its soil and water conservation function,amounts of litter and their water holding characteristics under three stands with different ages were examined.The results showed that the order of litter amount was near mature stand>middle-aged stand>young stand,and the litter amounts of young,middle-aged,and near mature stands were 5.37 t·hm-2,15.5 t·hm-2,23.31 t·hm-2,respectively.The water absorption rate of the litter decreased with time.The highest rate occurred within 0-30 min.The maximum water-holding capacity increased with the increase of stand ages:76.93 t·hm-2 for young stand，91.76 t·hm-2 in middle-aged stand,and 108.16 t·hm-2 for near-mature stand，with the equivalent water depths of 6.14 mm,8.04 mm,and 9.39 mm,respectively.
